How to Convert 25485 to Binary

Here we will show you step-by-step how to convert the decimal number 25485 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 25485 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 25485 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 25485 as a binary.

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

25485 ÷ 2 = 12742 with 1 remainder
12742 ÷ 2 = 6371 with 0 remainder
6371 ÷ 2 = 3185 with 1 remainder
3185 ÷ 2 = 1592 with 1 remainder
1592 ÷ 2 = 796 with 0 remainder
796 ÷ 2 = 398 with 0 remainder
398 ÷ 2 = 199 with 0 remainder
199 ÷ 2 = 99 with 1 remainder
99 ÷ 2 = 49 with 1 remainder
49 ÷ 2 = 24 with 1 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 25485 converted to binary is therefore:

110001110001101

So what we did on the page was to Convert A₁₀ to B₂, where A is the decimal number 25485 and B is the binary number 110001110001101. Which means that you can display decimal number 25485 to binary in mathematical terms as follows:

25485₁₀ = 110001110001101₂
