I would have expected my students to do this mentally

To divide 1056 by 40, you simply need to perform the following steps:

1. Write down the number 1056, which is the dividend (the number being divided).
2. Write down the number 40, which is the divisor (the number dividing the dividend).
3. Start dividing the dividend by the divisor, starting from the leftmost digit. In this case, divide 10 by 40. Since 10 is smaller than 40, we move to the next digit.
4. Bring down the next digit, which is 5, to the right of the remainder obtained from the previous step. Now we have a new dividend, which is 105.
5. Divide the new dividend (105) by the divisor (40). In this case, 105 divided by 40 is 2, with a remainder of 25.
6. Again, bring down the next digit, which is 6, to the right of the remainder obtained from the previous step. Now we have a new dividend, which is 256.
7. Divide the new dividend (256) by the divisor (40). In this case, 256 divided by 40 is 6, with a remainder of 16.
8. Finally, bring down the last digit, which is 0, to the right of the remainder obtained from the previous step. Now we have a new dividend, which is 160.

In summary, 1056 divided by 40 is equal to 26 with a remainder of 16.
