Dividing a multi-digit number by a one-digit number is written in long division: the divisor goes outside to the right; the quotient goes above the dividend. Look at the leading digits of the dividend: how many times the divisor “fits” there gives a digit of the quotient. Multiply that digit by the divisor, subtract from the current part of the dividend, bring down the next digit, and repeat until all places are used.
If after the last subtraction something smaller than the divisor but not zero is left, that is the remainder: you write the quotient and the remainder (for example, 17÷5=3 R 2). If it divides evenly, the remainder is zero.
Below — step-by-step work for 8724÷6 and 8725÷6; each step reveals the next action, and "Reset" reloads the same fixed example.
Write the quotient above the dividend, divisor to the right
Each step: “how many times?” → multiply → subtract → bring down
The times table for the divisor digit supports each estimate
The remainder is always less than the divisor
Divides evenly
