Remove Decimal part from number

i have a series of 100 arrays which contain about 4-5 digits number. for example, x=9588

i want x/256=37.453, i want to remove the .453 leaving only 37. then 37 * 256 = 9472, then 9588-9472=116,

i want the final answer to be like 116.

i have tried, floor, round and fix.but still not getting the answer i want. is it anything to do with the integer class? because all the number of array in int32. please help me. thank you
