Let's convert the decimal number 65 to binary without using a calculator:

Start by dividing 65 by 2:

65 ÷ 2 = 32 (Quotient) with a remainder of 1

Now, divide the quotient (32) by 2:

32 ÷ 2 = 16 (Quotient) with a remainder of 0

Now, divide the quotient (16) by 2:

16 ÷ 2 = 8 (Quotient) with a remainder of 0

Now, divide the quotient (8) by 2:

8 ÷ 2 = 4 (Quotient) with a remainder of 0

Now, divide the quotient (4) by 2:

4 ÷ 2 = 2 (Quotient) with a remainder of 0

Now, divide the quotient (2) by 2:

2 ÷ 2 = 1 (Quotient) with a remainder of 0

The Quotient is less than 2 (1), so we will transfer it to the beginning of the number as a reminder.

Now, write down the remainders obtained in reverse order:
