How to Convert 3721 to Binary

Here we will show you step-by-step how to convert the decimal number 3721 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 3721 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 3721 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 3721 as a binary.

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

3721 ÷ 2 = 1860 with 1 remainder
1860 ÷ 2 = 930 with 0 remainder
930 ÷ 2 = 465 with 0 remainder
465 ÷ 2 = 232 with 1 remainder
232 ÷ 2 = 116 with 0 remainder
116 ÷ 2 = 58 with 0 remainder
58 ÷ 2 = 29 with 0 remainder
29 ÷ 2 = 14 with 1 remainder
14 ÷ 2 = 7 with 0 remainder
7 ÷ 2 = 3 with 1 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 3721 converted to binary is therefore:

111010001001

So what we did on the page was to Convert A₁₀ to B₂, where A is the decimal number 3721 and B is the binary number 111010001001. Which means that you can display decimal number 3721 to binary in mathematical terms as follows:

3721₁₀ = 111010001001₂
