2020 Decimal in Binary

Let's convert the decimal number 2020 to binary without using a calculator:

Start by dividing 2020 by 2:

2020 ÷ 2 = 1010 (Quotient) with a remainder of 0

Now, divide the quotient (1010) by 2:

1010 ÷ 2 = 505 (Quotient) with a remainder of 0

Now, divide the quotient (505) by 2:

505 ÷ 2 = 252 (Quotient) with a remainder of 1

Now, divide the quotient (252) by 2:

252 ÷ 2 = 126 (Quotient) with a remainder of 0

Now, divide the quotient (126) by 2:

126 ÷ 2 = 63 (Quotient) with a remainder of 0

Now, divide the quotient (63) by 2:

63 ÷ 2 = 31 (Quotient) with a remainder of 1

Now, divide the quotient (31) by 2:

31 ÷ 2 = 15 (Quotient) with a remainder of 1

Now, divide the quotient (15) by 2:

15 ÷ 2 = 7 (Quotient) with a remainder of 1

Now, divide the quotient (7) by 2:

7 ÷ 2 = 3 (Quotient) with a remainder of 1

Now, divide the quotient (3) by 2:

3 ÷ 2 = 1 (Quotient) with a remainder of 1

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:
