8 bitwise is 00001000. >> means shift the bits to the right once, so the result is 00000100, which in decimal is 4

Shifting bit to right or left result to divide or multiply by two, due to the base 2 on wich binary numbers operate, as shifting a digit in decimal ( base 10 ) will result to divide or multiply by ten... So, there's no need to convert explicitly a number to binary representation to be able to get the result of a bit shifting ^^
