Learn How to Manually Convert Decimal to Octal?

Decimal numbers can be converted to octal numbers in two simple ways.

1. Dividing a decimal number by eight is an easy way to change it to an octal number. Divide by 8 to start, then record the remaining. Repeat the procedure until the remaining amount is less than 8. Reverse the order of the leftovers (bottom to top). Your response is here.

Now let's explain with an example. We'll change (572) 10 to (?) 8.

Decimal to octal

2. Using the previous image as a guide, we divided the number 572 by 8 to get 71, leaving a leftover of 4. After that, we divided 71 by 8 to obtain 8 and the residual was 7. We then divided 8 by 8 to get 0 and the result was 1. After arranging the leftovers from bottom to top, we will arrive at 1074. It is the solution.


The second approach takes longer but is easier. The process entails first converting a decimal number to a binary number, and then a binary number to an octal number.

The technique is the same to convert a decimal number to a binary number and vice versa. Here, we must divide by two instead of eight.

Here, we'll convert (572)10 into binary to get (1000111100)2.

We've already spoken about how to convert binary to octal, so let's now convert 1000111100 into octal. Visit find out, go to this page.
