The decimal numeral system in which numbers are expressed in scales of 10. Whereas the binary numeral system involves expressing numbers in scales of 2. Procedure: Suppose we want to convert decimal number 59 to binary. The number 59 is divided by 2 until the quotient is 1. The remainder(carry) that is accumulated(either 1 or 0) till the last sequence of operation that gives the quotient 1, is taken in the reverse order of creation so as to obtain 111011. 59/2 = 29 (1 is taken as carry) 29/2 = 14 (1 is taken as carry) 14/2 = 7 (1 is taken as carry) 7/2 = 3 (1 is taken as carry) 3/2 = 1 (1 is taken as carry) So when we reverse the carry, we get 11011. Finally, we place the final quotient at the very beginning of the 11011 to get 111011.
