The binary system count 0 and before shifting left. Therefore repeated divisions of 500 by 2 will yield the bits as reminders.
500/2 = 250 R 0 250/2 = 125 R 0 125/2 = 62 R 1 62/2 = 31 R 0 31/2 = 15 R 1 15/2 = 7 R 1 7/2 = 3 R 1 3/2 = 1 R 1 1/2 = 0 R 1
Collect the remainders to defne the bnary digits. 500 = 1 1 1 1 1 0 1 0 0 We need 9 bits, defined by the bnary number that will show on a binary odometer.
