How to Convert 27021 to Binary

Here we will show you step-by-step how to convert the decimal number 27021 to binary.

First, note that decimal numbers use 10 digits (0, 1, 2, 3, 4, 5, 6, 7, 8, and 9) and binary numbers use only 2 digits (0 and 1).

As we explain the steps to converting 27021 to binary, it is important to know the name of the parts of a division problem. In a problem like A divided by B equals C, A is the Dividend, B is the Divisor and C is the Quotient.

The Quotient has two parts. The Whole part and the Fractional part. The Fractional part is also known as the Remainder.

Step 1) Divide 27021 by 2 to get the Quotient. Keep the Whole part for the next step and set the Remainder aside.

Step 2) Divide the Whole part of the Quotient from Step 1 by 2. Again, keep the Whole part and set the Remainder aside.

Step 3) Repeat Step 2 above until the Whole part is 0.

Step 4) Write down the Remainders in reverse order to get the answer to 27021 as a binary.

Here we will show our work so you can follow along:

27021 ÷ 2 = 13510 with 1 remainder
13510 ÷ 2 = 6755 with 0 remainder
6755 ÷ 2 = 3377 with 1 remainder
3377 ÷ 2 = 1688 with 1 remainder
1688 ÷ 2 = 844 with 0 remainder
844 ÷ 2 = 422 with 0 remainder
422 ÷ 2 = 211 with 0 remainder
211 ÷ 2 = 105 with 1 remainder
105 ÷ 2 = 52 with 1 remainder
52 ÷ 2 = 26 with 0 remainder
26 ÷ 2 = 13 with 0 remainder
13 ÷ 2 = 6 with 1 remainder
6 ÷ 2 = 3 with 0 remainder
3 ÷ 2 = 1 with 1 remainder
1 ÷ 2 = 0 with 1 remainder

Then, when we put the remainders together in reverse order, we get the answer. The decimal number 27021 converted to binary is therefore:

110100110001101

So what we did on the page was to Convert A₁₀ to B₂, where A is the decimal number 27021 and B is the binary number 110100110001101. Which means that you can display decimal number 27021 to binary in mathematical terms as follows:

27021₁₀ = 110100110001101₂
