How Decimal to Octal Conversion Works
Decimal numbers use the base-10 number system, while octal numbers use base-8 with digits from 0 to 7. To convert a decimal number into octal, the number is repeatedly divided by 8 and the remainders are collected from bottom to top.
Example: Convert 64 from decimal to octal:
| Division | Quotient | Remainder |
|---|---|---|
| 64 ÷ 8 | 8 | 0 |
| 8 ÷ 8 | 1 | 0 |
| 1 ÷ 8 | 0 | 1 |
Reading the remainders from bottom to top gives 100. Therefore, decimal 64 equals octal 100.
