## To calculate 23 divided by 12, you can use long division. Here's how you can do it:

1. Start by dividing the first digit of the dividend (23) by the divisor (12). In this case, 2 divided by 1 equals 2.

- Write down the quotient, which is 2, above the division bar.

2. Multiply the quotient (2) by the divisor (12). In this case, 2 times 12 equals 24.

- Write down the product (24) below the first digit of the dividend (23).

3. Subtract the product (24) from the first part of the dividend (23). In this case, 23 minus 24 equals -1.

- Write down the result (-1) below the line, next to the product.

4. Bring down the next digit of the dividend, which is 3, next to the difference (-1). You have -13 now.

5. Repeat steps 1 to 4 with the new number (-13).

6. Divide -13 by 12. This time, the quotient is -1, as -1 divided by 1 equals -1. Write -1 above the division bar.

7. Multiply the new quotient (-1) by the divisor (12). In this case, -1 times 12 equals -12. Write down -12 below the number -13.

8. Subtract the new product (-12) from the difference (-13). In this case, -13 minus -12 equals -1.

- Write down the result (-1) below the line, next to the -12.

9. Since there are no more digits in the dividend to bring down, you've reached the end of the long division.

The final quotient is 1 with a remainder of -1, so the answer is 1 remainder -1.

Another way to express this is as a mixed number: 1 - 1/12. This means the answer is 1 whole unit and 1/12 of another unit.
