How to Convert Decimal Numbers to Binary?
There are multiple methods for decimal to binary conversion, including repeated division and using remainders. It also covers shortcuts for whole numbers and delves into the conversion of decimal fractions. You will get to know real-life applications, such as the importance of binary in computer science. Also, explore the best decimal-to-binary converter in this blog.
All apps and software development companies require an understanding of binary numbers. It is the base of all programming languages and digital technology, and it forms the basis for data storage, binary code, and the inner workings of computer processors. So, before you partner with a software development company understand the significance of binary conversions.
Understanding the Binary Systems
A binary system is a fundamental numbering system. It is a base-2 system, which means it only uses two digits: 0 and 1. Unlike the decimal system (base-10) that we commonly use which has 10 digits (0-9). The binary system operates with two values.
In a binary system, each digit in the decimal system represents an increasing power of 2, similar to how each digit in the decimal system represents a power of 10. In the binary number, select the far right digit, that holds the least value (2^0). And each subsequent digit to the left represents a value that is double that of the previous one.
For example: The binary number “1010” can be interpreted as
(0 * 2^0) + (1 * 2^1) + (0 * 2^2) + (1 * 2^3) = 0 + 2 + 0 + 8 = 10 in decimal.

Steps to Convert Decimal Numbers to Binary
Explore the steps below and easily convert decimal numbers to binary.
Step1: Start with the decimal number:
- Begin with the decimal number you want to convert. For this example, let’s use 53.
Step2: Divide by 2:
- Divide the decimal number by 2 or (53/2).
Step3: Note the quotient and remainder:
- Write down the quotient and remainder. In this case, 53 is divided by 2. It is equal to 26 with 1 remainder.
Step4: Repeat the process:
- Take the quotient from the previous step and divide it by 2
- Note down the new quotient and remainder
- For example, 26 divided by 2 equals 13 with the remainder of 0
Step5: Continue the division:
- Keep dividing the quotient by 2 and noting the quotient and remainder until the quotient becomes 0
Step6: Read all the remainder:
- Now read all remainders from bottom to top. In our example, all remainders are 110101.
Step7: This is the binary representation:
- The sequence of remainders (110101) is the binary representation of the number 53.
So, the decimal number 53 in binary is 110101. This process works for converting any decimal number to its binary equivalent.

Convert Binary Numbers to Decimal
Converting binary numbers to decimal is a simple process. Here are the steps to convert a binary number to its decimal equivalent.
Step1- Start with the binary number:
- Begin with the binary number you want to convert. For this, we can use 10101.
Step2- Assign power of 2:
- Start from the right and assign a power of 2 to each bit. The rightmost bit has the power of 2^0, the next one to the left has 2^1, the next 2^2, and so on; increasing by 1 for each bit to the left.
Step3- Multiply and sum:
- To find the decimal value of a binary number, you need to multiply each digit by its corresponding power of 2 and then add the results together.
Step4- This is the decimal representation:
- The sum from the previous step is the decimal representation of the binary number.
Let’s understand it with the help of the below representation:
Binary number= 10101
- Starting from the right:
- 1 * 2^0 = 1
- 0 * 2^1 = 0
- 1 * 2^2 = 4
- 0 * 2^3 = 0
- 1 * 2^4 = 16
- Sum the results:
So, the binary number 10101 is equal to the decimal number 21.
