Start by dividing 1101 by 2:

1101 ÷ 2 = 550 (Quotient) with a remainder of 1

Now, divide the quotient (550) by 2:

550 ÷ 2 = 275 (Quotient) with a remainder of 0

Now, divide the quotient (275) by 2:

275 ÷ 2 = 137 (Quotient) with a remainder of 1

Now, divide the quotient (137) by 2:

137 ÷ 2 = 68 (Quotient) with a remainder of 1

Now, divide the quotient (68) by 2:

68 ÷ 2 = 34 (Quotient) with a remainder of 0

Now, divide the quotient (34) by 2:

34 ÷ 2 = 17 (Quotient) with a remainder of 0

Now, divide the quotient (17) by 2:

17 ÷ 2 = 8 (Quotient) with a remainder of 1

Now, divide the quotient (8) by 2:
