Long division by two digits

You learn long division by a two-digit number, using a list to help you.

How to work it out

  1. Write out the multiples: 1, 2, 3, 5 and 10 times the number you divide by.
  2. From the left, take the smallest piece it goes into.
  3. Look in your list how many times it goes, take that away and bring down the next digit.
  4. Keep going until all the digits are used.

336 ÷ 12

  1. Make a list: 12, 24, 60, 120.
  2. Take 33: 12 goes in 2 times, 2 × 12 = 24, and 9 is left over.
  3. Bring down the 6: 96.
  4. 12 goes in 8 times, because 5 × 12 = 60 and 3 × 12 = 36, which makes 96.
  5. The answer is 28.

468 ÷ 18

  1. Make a list: 18, 36, 90, 180.
  2. Take 46: 18 goes in 2 times, 2 × 18 = 36, and 10 is left over.
  3. Bring down the 8: 108.
  4. 18 goes in 6 times, because 5 × 18 = 90 and 1 × 18 = 18, which makes 108.
  5. The answer is 26.

255 ÷ 15

  1. Make a list: 15, 30, 75, 150.
  2. Take 25: 15 goes in once, and 10 is left over.
  3. Bring down the 5: 105.
  4. 15 goes in 7 times, because 5 × 15 = 75 and 2 × 15 = 30, which makes 105.
  5. The answer is 17.

336 ÷ 12

  1. Make a list: 12, 24, 60, 120.
  2. Take away 10 × 12 = 120: 336 − 120 = 216.
  3. Take away another 10 × 12 = 120: 216 − 120 = 96.
  4. Take away 5 × 12 = 60: 96 − 60 = 36.
  5. Take away 2 × 12 = 24: 36 − 24 = 12.
  6. Take away 1 × 12 = 12: 12 − 12 = 0.
  7. Add up the chunks: 10 + 10 + 5 + 2 + 1 = 28.
  8. The answer is 28.
