3-Digit / 1-Digit — Multiply & Divide Pathway
Dividing a 3-digit number by 1 digit
- Use the bus stop method — work from left to right.
- Divide each digit in turn.
- If a digit is too small, combine it with the next one.
- Write the answer on top.
Example: 432 / 4
- Step 1: 4 into 4 = 1. Write 1.
- Step 2: 4 into 3 = 0, remainder 3. Write 0, carry 3.
- Step 3: 4 into 32 = 8. Write 8.
- Answer: 108.
Your turn
- Try: 246 / 3.
- 3 into 2 does not go. Combine: 3 into 24 = 8.
- 3 into 6 = 2.
- Answer: 82.
Common Mistakes to Avoid
- Forgetting to write 0 when the divisor does not fit. If 4 does not go into 3, write 0 and carry the 3.
- Losing track of carries across three digits. Write each carry clearly.
Real-Life Example
A school packs 432 exercise books into boxes of 4. 432 / 4: 4 into 4 = 1, 4 into 3 = 0 remainder 3 (write 0, carry 3), 4 into 32 = 8. Answer: 108 boxes.
Extra Support Hints
- Work left to right, one digit at a time.
- If a digit is too small, combine it with the next digit before dividing.
