How to Convert 10003 to Binary

Here we will show you step-by-step how to convert the decimal number 10003 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 10003 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 10003 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 10003 as a binary.

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

10003 ÷ 2 = 5001 with 1 remainder
5001 ÷ 2 = 2500 with 1 remainder
2500 ÷ 2 = 1250 with 0 remainder
1250 ÷ 2 = 625 with 0 remainder
625 ÷ 2 = 312 with 1 remainder
312 ÷ 2 = 156 with 0 remainder
156 ÷ 2 = 78 with 0 remainder
78 ÷ 2 = 39 with 0 remainder
39 ÷ 2 = 19 with 1 remainder
19 ÷ 2 = 9 with 1 remainder
9 ÷ 2 = 4 with 1 remainder
4 ÷ 2 = 2 with 0 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 10003 converted to binary is therefore:

10011100010011

So what we did on the page was to Convert A₁₀ to B₂, where A is the decimal number 10003 and B is the binary number 10011100010011. Which means that you can display decimal number 10003 to binary in mathematical terms as follows:

10003₁₀ = 10011100010011₂
