Conversion Method

How Decimal to Binary Conversion Works

To convert decimal to binary:

  1. Divide the decimal number by 2
  2. Record the remainder (0 or 1)
  3. Divide the quotient by 2 again
  4. Repeat until quotient becomes 0
  5. Read remainders in reverse order for binary result

Example: Convert 10 (DEC) to binary:

10 ÷ 2 = 5 remainder 0

5 ÷ 2 = 2 remainder 1

2 ÷ 2 = 1 remainder 0

1 ÷ 2 = 0 remainder 1

Read remainders backwards: 1010 (BIN)
