The first error appears in Step 1. In that step, the student is trying to determine how many times 12 goes into the first part of the dividend (43).
12 goes into 43 3 times, not 1 or 2. So, the correct answer to 432 / 12 is 36 (since 12 times 3 is 36, and the remainder after subtracting from 43 would lead on to bring down the next digit for another step with 12).
The correct breakdown should be:
- 12 goes into 43 3 times (since 12 x 3 = 36).
- Subtract 36 from 43 to get a remainder of 7, then bring down the next digit (2).
- Now you have 72; 12 goes into 72 6 times (since 12 x 6 = 72).
- Subtract 72 from 72 to reach a remainder of 0.
Thus, the overall answer is that 432 divided by 12 equals 36.
