PLEASE HELP What number should be placed in the box to help complete the division calculation?

Explanation:
Note the 2 in the 32 up top. This 2 will multiply with the 13 on the far left side to get 2*13 = 26 which goes in the box under the 331. Specifically, the 26 goes under the 33 and the 1 is carried down after the subtraction.
Answer: 325 6/13 or 325 R 6
