Lesson 4: Divide Multi-Digit Numbers6.NOS.2

I can…

I can divide multi-digit whole numbers and explain the meaning of the quotient and remainder.

Key words

• Dividend — The number you are splitting up in a division problem.
• Divisor — The number you split by in a division problem.
• Quotient — The answer when you divide.
• Remainder — What is left over when a number does not divide evenly.
• Partial quotients — A way to divide by breaking the problem into smaller, easier steps.

Steps

1. I want 1,344 ÷ 12. The dividend is 1,344 and the divisor is 12.
2. First I take a big easy chunk: 12 × 100 = 1,200. I subtract: 1,344 − 1,200 = 144.
3. Now I divide 144: 12 × 12 = 144. I subtract: 144 − 144 = 0, so nothing is left.
4. I add my chunks: 100 + 12 = 112. So 1,344 ÷ 12 = 112.
5. I check by multiplying: 12 × 112 = 1,344. Correct, and the remainder is 0.

Try it

What is 2,352 ÷ 16?

Check your answer

147

16 × 147 = 2,352. Check: 16 × 100 = 1,600, 16 × 40 = 640, 16 × 7 = 112. 1,600 + 640 + 112 = 2,352.
