HOW TO CONVERT 1000 TO BINARY
Method: divide by 2, collect remainders
1000 ÷ 2 = 500 remainder 0
500 ÷ 2 = 250 remainder 0
250 ÷ 2 = 125 remainder 0
125 ÷ 2 = 62 remainder 1
62 ÷ 2 = 31 remainder 0
31 ÷ 2 = 15 remainder 1
15 ÷ 2 = 7 remainder 1
7 ÷ 2 = 3 remainder 1
3 ÷ 2 = 1 remainder 1
1 ÷ 2 = 0 remainder 1
