Answer
The check was done incorrectly.
Work Step by Step
The answer was correct, but the student performed the check incorrectly. To check division, it was correct to multiply the 6 by 497 to get 2982. However, the student forgot to add the 5, which is the remainder found. Doing this, the student would have gotten 2987, which was the original number, meaning that the division was performed correctly.
