Worked examples
Two examples
Example 1
263 ÷ 7 =
- How many times does 7 go into 263? 37 times: 7 × 37 = 259.
- 263 − 259 = 4 left over. The remainder must be less than 7.
- Check: 7 × 37 + 4 = 263.
Answer: 37 R 4
Example 2
1,935 ÷ 5 =
- 5 goes into 19 three times (15), 4 left; bring down the 3: 43.
- 5 goes into 43 eight times (40), 3 left; bring down the 5: 35. 5 goes into 35 seven times, nothing left.
- Check: 5 × 387 = 1,935.
Answer: 387
