9001 Decimal in Binary

Let's convert the decimal number 9001 to binary without using a calculator:

Start by dividing 9001 by 2:

9001 ÷ 2 = 4500 (Quotient) with a remainder of 1

Now, divide the quotient (4500) by 2:

4500 ÷ 2 = 2250 (Quotient) with a remainder of 0

Now, divide the quotient (2250) by 2:

2250 ÷ 2 = 1125 (Quotient) with a remainder of 0

Now, divide the quotient (1125) by 2:

1125 ÷ 2 = 562 (Quotient) with a remainder of 1

Now, divide the quotient (562) by 2:

562 ÷ 2 = 281 (Quotient) with a remainder of 0

Now, divide the quotient (281) by 2:

281 ÷ 2 = 140 (Quotient) with a remainder of 1

Now, divide the quotient (140) by 2:

140 ÷ 2 = 70 (Quotient) with a remainder of 0

Now, divide the quotient (70) by 2:

70 ÷ 2 = 35 (Quotient) with a remainder of 0

Now, divide the quotient (35) by 2:

35 ÷ 2 = 17 (Quotient) with a remainder of 1

Now, divide the quotient (17) by 2:

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

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:
