The answer to that question is 256. When you divide 256 by 40, you'll get a quotient of 6. When you multiply 40 by its quotient which is 6, you'll have 240 as an answer. Therefore, when you subtract 256 to 240, you'll get a remainder of 16. To put it simply, here is a computation.
40/256= 6
6x40=240
256-240=16
Therefore, the answer is 256.
