How to convert Binary to Octal?

One can achieve this by using the following steps:
Firstly, group the binary numbers in a group of three from right to left. Accordingly, add extra zeros at the beginning if needed.
Then replace each group with the corresponding octal number from the following table.
For example, let us convert a binary number 10 to octal.
Grouping the number in sets of three, and adding additional zeros, we have 010.
From the below table, 010 = 2 in octal
