1. Divide the decimal number by 8.

2. Write down the remainder.

3. Divide the quotient by 8.

4. Write down the remainder.

5. Repeat steps 3 and 4 until the quotient is zero.

6. Write the remainders in reverse order.

For example, let's convert decimal number 10 to octal number:

1. 10 / 8 = 1 remainder 2
