Python Decimal to Octal Conversion – This tutorial explains the logic of decimal number to octal number conversion process. It also explains the Python code to convert a dcimal nuber into octal number.

How to Convert a decimal Number to Octal Number

- We divide the decimal number by base 8 and get the quiotient and remainder. Example: divide 119 by 8, quotient1 is 17 and remainder1 is 7.
- Then we divide the quotient by base 8 and get the quotient and remainder. The Example continues from step 1: divide quotient1 by 8, quotient2 is 1 and remainder2 is 6.
- This process continues until the quotient bcomes zero. The example continues from step 2: divide quotient2 by 8, now quotient3 is 0 (zero), so we stop, and remainder3 is 1.
- Now we write all remainders in reverse order to get the required binary number. The example continus from step 3. We will write remainder3 = 1,remainder2=6,remainder1=7 (in reverse order) so that we will get the required binary number 167.

## The Source code of python Program Decimal to Octal Number Conversion
