Answer: 1. Write down the division problem: 9240 ÷ 7.

2. Start by dividing the first digit of the dividend (9) by the divisor (7). In this case, 9 ÷ 7 equals 1 with a remainder of 2.

3. Bring down the next digit of the dividend (2) next to the remainder from the previous step. This gives us 22.

4. Divide 22 by 7. The result is 3 with a remainder of 1.

5. Bring down the next digit of the dividend (4) next to the remainder from the previous step. This gives us 14.

6. Divide 14 by 7. The result is 2 with no remainder.

7. Finally, bring down the last digit of the dividend (0) next to the previous quotient. This gives us 20.

8. Divide 20 by 7. The result is 2 with a remainder of 6.

Therefore, when we divide 9240 by 7, the quotient is 1320 with a remainder of 6.

In summary, 9240 divided by 7 equals 1320, with a remainder of 6.
