WebFeb 19, 2014 · 1. First of all, this is XOR not subtraction. Similar bits being XOR'ed always equal 0, different bits (no matter the order) in an XOR always equal 1. 0 XOR 0 = 0, 1 XOR 1 = 0, 1 XOR 0 = 1, 0 XOR 1 = 1. Once you have grasped this firmly, it makes the math easier and behaves very similarly to traditional long division as far as having leading ...
