Learn how to divide binary numbers with easy explanations, examples, and practice activities
What is Binary Division?
Binary division is a way to divide numbers using only two digits: 0 and 1. Computers use this method because they only understand these two numbers.
Just like regular division, binary division helps us split numbers into equal parts. The main difference is that instead of using ten digits (0-9) like in decimal, we only use two digits (0 and 1).
In binary division:
- The number being divided is called the dividend
- The number we divide by is called the divisor
- The answer is called the quotient
- Any left-over part is called the remainder
Key Concept
Binary division uses only 0 and 1. It follows the same rules as decimal division but with only two possible digits.
How to Divide Binary Numbers
Dividing binary numbers is similar to regular long division. Follow these steps:
Binary Division Rules
0 ÷ 0 = undefined
0 ÷ 1 = 0
1 ÷ 0 = undefined
1 ÷ 1 = 1
Remember
Just like with decimal division, you cannot divide by zero in binary division. The rules are similar but with only two possible digits.
Binary Division Examples
Let's practice with some examples:
Example 1: 110 (6) ÷ 10 (2)
Step-by-step:
1. 10 goes into 11 once (1)
2. Multiply 10 × 1 = 10
3. Subtract: 11 - 10 = 01
4. Bring down the next digit (0) to make 10
5. 10 goes into 10 once (1)
6. Multiply 10 × 1 = 10
7. Subtract: 10 - 10 = 00
Answer: 11 (3)
Example 2: 1010 (10) ÷ 10 (2)
Step-by-step:
1. 10 goes into 10 once (1)
2. Multiply 10 × 1 = 10
3. Subtract: 10 - 10 = 00
4. Bring down next digit (1) to make 001
5. 10 is larger than 1, so write 0 in quotient
6. Bring down next digit (0) to make 10
7. 10 goes into 10 once (1)
8. Multiply 10 × 1 = 10
9. Subtract: 10 - 10 = 00
Answer: 101 (5)
Practice Tip
Try converting the binary numbers to decimal to check your answers. For example: 1010 binary is 10 in decimal, 10 binary is 2, and 10 ÷ 2 = 5, which is 101 in binary.

Frequently Asked Questions
Here are answers to common questions about binary division:
Binary Number Trivia
Discover interesting facts about binary numbers:
Binary Origins
The binary number system was first described by Gottfried Leibniz in the 17th century, though similar concepts appeared in ancient Egypt and India.
Computer Language
All data in computers - text, images, videos - is ultimately stored and processed as binary numbers (sequences of 0s and 1s).
Space Communication
NASA uses binary codes to communicate with spacecraft. The Voyager Golden Record includes binary instructions for playback.
Binary in Nature
Binary systems appear in nature too! The genetic code in DNA uses a quaternary system (four bases) that can be represented with binary pairs.
