5th grade math · Unit 4: Dividing whole numbers

Long division, two-digit divisors

What this lesson shows

1,176 ÷ 24: 117 tens ÷ 24 is about 4 tens, each step said in place value.

The worked example

The lesson works this one step by step: 1,176 ÷ 24. Then your kid tries one like it on paper.

The steps

  1. Start with digits big enough
  2. Try multiples to divide
  3. Multiply, subtract, bring down
  4. Check by multiplying back

Helping at home

Start with the first digits big enough to hold the divisor. For each digit, try multiples of the divisor: one that fits and the next, too big. Say what place the new digit holds. A remainder is written as a fraction of the divisor, as Florida asks.

If your kid gets stuck

Try multiples of the divisor. Write any remainder as a fraction.
