Enter a decimal number: Step 1: 56/2, Remainder = 0, Quotient = 28
Step 2: 28/2, Remainder = 0, Quotient = 14
Step 3: 14/2, Remainder = 0, Quotient = 7
Step 4: 7/2, Remainder = 1, Quotient = 3
Step 5: 3/2, Remainder = 1, Quotient = 1
Step 6: 1/2, Remainder = 1, Quotient = 0
56 in decimal = 111000 in binary
