How to Convert 3915 to Binary

Here we will show you step-by-step how to convert the decimal number 3915 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 3915 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 3915 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 3915 as a binary.

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

3915 ÷ 2 = 1957 with 1 remainder
1957 ÷ 2 = 978 with 1 remainder
978 ÷ 2 = 489 with 0 remainder
489 ÷ 2 = 244 with 1 remainder
244 ÷ 2 = 122 with 0 remainder
122 ÷ 2 = 61 with 0 remainder
61 ÷ 2 = 30 with 1 remainder
30 ÷ 2 = 15 with 0 remainder
15 ÷ 2 = 7 with 1 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 3915 converted to binary is therefore:

111101001011

So what we did on the page was to Convert A₁₀ to B₂, where A is the decimal number 3915 and B is the binary number 111101001011. Which means that you can display decimal number 3915 to binary in mathematical terms as follows:

3915₁₀ = 111101001011₂
