Long Division — Step-by-Step Method

Long division is a systematic method for dividing large numbers by breaking the problem into simpler steps: Divide → Multiply → Subtract → Bring Down (remember: Dad, Mom, Sister, Brother or Dirty Monkeys Smell Bad).

Example: 745 ÷ 5
Step 1: 7÷5=1 remainder 2 → Write 1, bring down 4 → 24
Step 2: 24÷5=4 remainder 4 → Write 4, bring down 5 → 45
Step 3: 45÷5=9 remainder 0 → Write 9
Answer: 149 (verify: 149×5=745 ✓)

Dividend	Divisor	Quotient	Remainder
156	7	22	2
845	12	70	5
1000	13	76	12
9999	99	101	0

How do you check long division answers?

Verify using: (Divisor × Quotient) + Remainder = Dividend. Example: 845÷12 = 70 R5. Check: 12×70+5 = 840+5 = 845 ✓.

What does remainder mean in division?

The remainder is what is left over after dividing as many complete times as possible. For 17÷5: 5 goes into 17 three times (5×3=15), leaving 17−15=2. So quotient=3, remainder=2, written as 17÷5=3 R2 or 3²⁄₅.
