Continue until you get to 2 to the 0th power (or 1) which gives us our last bit. So 140 is divisible by 128 (2^7) and the remainder is 12. 12 is divisible by 8 (2^3) and leaves 4 which is divisible by 2^2. So we have one's bits in the 7, 3, and 2 places and zero's elsewhere. 140 decimal = 1000110 binary. imdb crimson peak
