How to Convert 12521 to Binary

Here we will show you step-by-step how to convert the decimal number 12521 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 12521 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 12521 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 12521 as a binary.

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

12521 ÷ 2 = 6260 with 1 remainder
6260 ÷ 2 = 3130 with 0 remainder
3130 ÷ 2 = 1565 with 0 remainder
1565 ÷ 2 = 782 with 1 remainder
782 ÷ 2 = 391 with 0 remainder
391 ÷ 2 = 195 with 1 remainder
195 ÷ 2 = 97 with 1 remainder
97 ÷ 2 = 48 with 1 remainder
48 ÷ 2 = 24 with 0 remainder
24 ÷ 2 = 12 with 0 remainder
12 ÷ 2 = 6 with 0 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 12521 converted to binary is therefore:

11000011101001

So what we did on the page was to Convert A₁₀ to B₂, where A is the decimal number 12521 and B is the binary number 11000011101001. Which means that you can display decimal number 12521 to binary in mathematical terms as follows:

12521₁₀ = 11000011101001₂
