How to Convert 20822 to Binary

Here we will show you step-by-step how to convert the decimal number 20822 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 20822 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 20822 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 20822 as a binary.

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

20822 ÷ 2 = 10411 with 0 remainder
10411 ÷ 2 = 5205 with 1 remainder
5205 ÷ 2 = 2602 with 1 remainder
2602 ÷ 2 = 1301 with 0 remainder
1301 ÷ 2 = 650 with 1 remainder
650 ÷ 2 = 325 with 0 remainder
325 ÷ 2 = 162 with 1 remainder
162 ÷ 2 = 81 with 0 remainder
81 ÷ 2 = 40 with 1 remainder
40 ÷ 2 = 20 with 0 remainder
20 ÷ 2 = 10 with 0 remainder
10 ÷ 2 = 5 with 0 remainder
5 ÷ 2 = 2 with 1 remainder
2 ÷ 2 = 1 with 0 remainder
1 ÷ 2 = 0 with 1 remainder

Then, when we put the remainders together in reverse order, we get the answer. The decimal number 20822 converted to binary is therefore:

101000101010110

So what we did on the page was to Convert A₁₀ to B₂, where A is the decimal number 20822 and B is the binary number 101000101010110. Which means that you can display decimal number 20822 to binary in mathematical terms as follows:

20822₁₀ = 101000101010110₂
