Select the cell where you want the result.
Type `=`.
Enter the dividend (the number you want to divide).
Type `/`.
Enter the divisor (the number you want to divide by).
Press `Enter`.
To divide two cells: `=A1/B1`
To divide a cell by a constant: `=A1/10`
To divide a range by a constant (fill down/right): enter `=A1/10`, then drag the fill handle
To divide a range by a single cell: `=A1/$B$1` (use `$` to lock the divisor cell)
To divide multiple columns by the same divisor: `=A1/$B$1`, then fill across/down
To divide using percentages: `=A1/0.25` (or convert a percent like `=A1/(B1/100)`)
To avoid division by zero: `=IF(B1=0,””,A1/B1)`
To divide using whole-number division (quotient): `=QUOTIENT(A1,B1)`
To get remainder: `=MOD(A1,B1)`
