How to convert Decimal to Octal?

To convert Decimal to Octal, we need to divide the Decimal value by 8 until the quotient is 0. Then, we need to combine all the remainders together to get the final Octal value.

Example

Let's convert the Decimal value 10 to Octal.

First, we need to divide the Decimal value by 8 until the quotient is 0.

Decimal Value	Quotient	Remainder
10	1	2
1	0	1

Now, we need to combine all the remainders together to get the final Octal value. In this case, the final Octal value is 12. This is the Octal representation of the Decimal value 10.
