16384/256 = 64 but how? Do it on a calculator!!. Haven't you learned in school how to divede by long hand? You take 1638/256=6 plus a remainder 102. Then put the last 4 in front of this number like this:
1024/256=4. So, you take the first result which was a 6 and this last one which is a 4 as:64. And that's how it's done.Good luck.
