How Decimal to Octal Conversion Works
Octal numbers use base-8, meaning they only use digits from 0 to 7. The conversion process involves:
- Dividing the decimal number by 8 repeatedly
- Recording the remainder at each step
- Reading the remainders in reverse order
For example, to convert 25 (decimal) to octal:
25 ÷ 8 = 3 remainder 1
3 ÷ 8 = 0 remainder 3
Result: 31 (octal)
