Division in Google Sheets sits quietly behind almost every business decision you make. Revenue per lead, cost per click, hours per client, units per shipment – they’re all just quotients. When you know how to divide confidently, you stop guessing and start seeing patterns: which campaigns are overpaying for results, which products really drive margin, where your team’s time is being burned.But once your sheet grows beyond a few rows, manual division turns into a slog: dragging fill handles, fixing `#DIV/0!` errors, reformatting percentages. That’s where delegating the work to an AI computer agent changes the game. Instead of touching every formula yourself, you describe the outcome: “Divide column B by C for all new rows, format as percent, ignore blanks.” The agent opens Google Sheets like a human, applies the right formulas, handles errors, and repeats the workflow every time your data updates – freeing you to make decisions instead of babysitting cells.
If you run a business, agency, or sales team, Google Sheets is probably your quiet operating system. And hidden inside most of your dashboards is one tiny move that decides whether your numbers make sense: division.
From ROAS and CAC to utilization and profit per client, you are constantly dividing. The workflow is simple when it’s one row. It becomes painful when it’s thousands – and that’s exactly where an AI computer agent like Simular steps in.
Before you automate anything, you need to be fluent in the manual moves.
= to start a formula./.Your formula looks like =A2/B2. Google Sheets returns the quotient. Use this for quick, one-off calculations.
The DIVIDE function is the explicit version of the slash.
=DIVIDE(.,, then click the divisor cell (B2).) and press Enter.You now have =DIVIDE(A2,B2). This is easier to read for non-spreadsheet people on your team.
If you only care about whole units (for example, full boxes shipped, not partial):
=QUOTIENT(.).=QUOTIENT(10,3) returns 3 and drops the remainder.
This is where most teams start burning time.
Imagine column A holds revenue per client and C1 holds total clients. You want revenue per client for hundreds of rows.
=A2/$C$1.The dollar signs turn C1 into an absolute reference, so every row divides by the same cell.
If you receive new data frequently, dragging formulas is fragile.
=ARRAYFORMULA(A2:A/B2:B).Google Sheets will divide each value in column A by the value in the same row of column B and spill the results down automatically.
#DIV/0! With IFERRORDivision by zero or blank cells can wreck a client-facing report.
Wrap your formulas like this:
=IFERROR(A2/B2, "") to return an empty cell on error.=IFERROR(DIVIDE(A2,B2), "Check data") to show a custom warning.After dividing, your numbers often represent ratios or conversion rates.
Now your sheet reads like a story, not a raw data dump.
All of this works beautifully for a single report. But in a real business you likely:
You become the human macro: download, paste, drag formulas, fix errors, reformat. That’s the exact kind of routine computer work an AI computer agent is built to absorb.
Simular’s agents can operate your browser and desktop like a focused teammate. Instead of wiring APIs, you describe the workflow in plain language and let the agent handle the clicks.
Here’s a typical delegation:
/, DIVIDE, or ARRAYFORMULA.IFERROR to avoid ugly messages.Because Simular Pro is a production-grade computer-use agent, every step is transparent: you can inspect each action, tweak the logic, and rerun the workflow confidently.

The smart play is to combine both worlds.
/, DIVIDE, QUOTIENT, ARRAYFORMULA, and IFERROR to design the perfect division workflow for one sheet.You stay in the loop as the strategist, not the person dragging fill handles. That’s the real promise of agents: the math still happens in Google Sheets, but the busywork stops happening in your brain.
To divide two cells, use the slash operator. Click the result cell, type `=`, then select the first cell, type `/`, and select the second cell. For example, `=A2/B2` divides A2 by B2. Press Enter to confirm. This is the fastest method for simple, cell-by-cell division and works perfectly for most day-to-day calculations in Google Sheets.
Use `ARRAYFORMULA` to divide full columns. In a blank column, enter `=ARRAYFORMULA(A2:A/B2:B)` and press Enter. Google Sheets will automatically apply row-by-row division for every pair of values in columns A and B, spilling results downward. This is ideal for large datasets where you frequently add new rows and don’t want to manually drag formulas.
Wrap your division in `IFERROR`. Instead of `=A2/B2`, use `=IFERROR(A2/B2, "")` to show a blank when division fails, or `=IFERROR(A2/B2, "Check data")` to display a custom message. This keeps dashboards clean and readable, especially when some divisors are zero or cells are empty during early data loads.
Place the divisor in a single cell, for example C1. In the first result cell, enter `=A2/$C$1` and press Enter. Then drag the fill handle down the column. The dollar signs make C1 an absolute reference, so every row divides by the same value. This is perfect for normalizing metrics, such as revenue per fixed budget or cost per standard unit.
First perform the division using `=A2/B2` or `=DIVIDE(A2,B2)`. Then select the result cells and click the Percent format button in the toolbar. Adjust decimal places with the increase/decrease decimal icons. Google Sheets will multiply the underlying ratio by 100 and show it as a percentage, ideal for conversion rates, engagement ratios, or utilization metrics.
