## Decimal to Binary Conversion

Before learning how to convert decimal to binary in a number system, let’s first understand what a decimal number system is and what is a binary number system.

### Decimal Number System

The number system that has a base value of 10 is called Decimal Number System. Decimal Numbers are consist of the following digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.

### Binary Number System

A binary Number System is a base-2 number system that uses two states 0 and 1 to represent a number. For example: 01, 111, etc.

All the decimal numbers have their corresponding binary numbers. These binary numbers are used in computer applications and used for programming or coding purposes. This is because binary digits, 0 and 1 are only understood by computers.

### Steps for Decimal to Binary Conversion

For converting Decimal numbers into binary numbers, use different methods such as formula, division methods, and so on. Here, use the remainder formula. Steps to convert decimal number to binary number using decimal to the binary formula are as follow,

Step 1: Divide the given decimal number by 2, and find the remainder (Ri).

Step 2: Now divide the quotient (Qi) that is obtained in the above step by 2, and find the remainder.

Step 3: Repeat the above steps 1 and 2, until 0 is obtained as a quotient.

Step 4: Write down the remainder in the following manner: the last remainder is written first, followed by the rest in the reverse order (Rn, R(n – 1) …. R1). thus binary conversion of the given decimal number will be obtained.

Let’s understand the above steps with the help of an example

Example: Convert 17 to Binary Form

Solution:

Following the above steps we will divide 17 by 2 successively. The division process is shown the image added below:

Hence the Binary Equivalent of 17 is 10001.
