A Binary Number consists of 0 s & 1 s only (Two Digits) whereas a Decimal Number Consists of 0,1,2,3,4,5,6,7,8,9 (ten digits) . For Example ( 111 )2 is binary number equivalent to decimal number ( 7 )10. A bit is a single Binary Digit. The binary number above has three bits. Algorithm Divide the dividend(number) by divisor 2 and get the remainder & the quotient. If the quotient is not zero, then quotient becomes dividend and follow above step. As quotient has now become zero, the binary number is all the remainders from bottom or from right side which consists of 0 & 1.
