This is my fourth article on octal arithmetic. In this article I am going to solve some examples on octal division. This is very easy task and principles and rules of division remain same. Here are articles on octal number systems. These articles provide tutorials on mathematical operations on octal number systems which includes octal numbers addition,octal numbers subtraction and octal numbers multiplication.
Key Questions:
- How to perform division in octal numbers system?
- How to perform fractional octal numbers division
Division In Octal Number System (Solved Examples):
To solve division examples you must know how to perform multiplication on octal numbers. I will solve examples on each case. First case in which dividend and divisor both are integers. Second case in which dividend has an octal point and divisor is an integer. Third case in which both dividend and divisor both have floating point numbers. You can check your results by using this online converter.

Answer:53.27)8
Example#03:737.72)8÷1.2)8
Shifting octal point makes the problem easy. According to mathematical rule shifting octal point of numerator upto one place then you have to shift octal point of denominator upto one place as well.
7377.2)8÷12)8
After shifting octal point divisor/denominator is free from octal point.
Let's make table for 12 and it's multiples.
