Decimal to Binary conversion is the process of translating numbers from base-10 (decimal system) into base-2 (binary system). The decimal system uses digits from 0–9, while binary uses only two digits: 0 and 1. Computers process data in binary, which makes this conversion essential for programming, networkingand digital electronics.

Binary numbers are the language of computers. By converting decimal numbers into binary, you can:

• Understand how data is processed in computing systems.
• Work with networking protocols, IP addressesand subnets.
• Learn number system concepts for academic purposes.
• Debug or test algorithms that depend on binary operations.

To convert a decimal number to binary manually, divide the number by 2 and record the remainders. Continue dividing until the quotient is 0. The binary number is the remainders read in reverse order.

Example: Convert 428.4 to binary.

428 ÷ 2 = 214 remainder 0
214 ÷ 2 = 107 remainder 0
107 ÷ 2 = 53 remainder 1
53 ÷ 2 = 26 remainder 1
26 ÷ 2 = 13 remainder 0
13 ÷ 2 = 6 remainder 1
6 ÷ 2 = 3 remainder 0
3 ÷ 2 = 1 remainder 1
1 ÷ 2 = 0 remainder 1

Integer Part: 428 → 110101100

Fractional Part: 0.4 → .011001 (approx.)

Result: 428.4 → 110101100.011001₂
