How to Convert Decimal to Octal Values

The best method used in decial to octal conversion is the process of successive division. Divide the decimal number by 8; the remainder is the LSB of the octal number. If the quotation is zero, the conversion is complete. Otherwise repeat step (a) using the quotation as the decimal number. The new remainder is the next most significant bit of the octal number.

Example : Convert the decimal number 9410 into its octal equivalent.

First divide 94 by 8; the result is 11 as quotation with 6 as remainder.

Now make last quotation 11 as the new decimal number and divide 11 by 8; the result is 1 as quotation with 3 as remainder.

Now make last quotation 1 as the new decimal number and divide 1 by 8; the result is 0 as quotation with 1 as remainder.

Starting from the last remainder whose quotation is zero, treat it as the MSB and write all remainders in reverse sequence after that we get the answer; 136

So, 9410 = 1368
