Use the modulo key if your calculator has one: enter the dividend, the modulo symbol, then the divisor
If there is no modulo key, divide the numbers and note the decimal result
Multiply the whole-number quotient by the divisor
Subtract that product from the dividend
The result is the remainder
For example, 17 ÷ 5 = 3.4, so 17 − (3 × 5) = 2
On some scientific calculators, use the integer part of the quotient to find the remainder
If your calculator supports functions like INT, FLOOR, or MOD, use MOD directly when available
