Convert 299012 into Base 8.

Solution:

The given number which is
299012 is written in Base 10. 299012 can also be written as 29901210. If you don't see any subscript at the given number, then that number is written in Base 10. Base 10 number is also called decimal system.  The digits of Base 10 number are 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. Base 10 number is a common number that we are using right now in everyday life.

On the other hand, Base 8 number is a number whose digits are 0, 1, 2, 3, 4, 5, 6, and 7. If you see a subscript of 8 at the given number, then that number is written in Base 8. Base 8 number is also called octal system.

Now, let's convert
299012 into Base 8. How? Let's divide 299012 by 8 as follows:

299012 ÷ 8 = 37376 + R(4)

Next, let's divide the quotient, which is 37376, as follows:

299012 ÷ 8 = 37376 + R(4)
37376 ÷ 8 =   4672 + R(0)

Do the same thing with 4672 until the quotient is 0 as follows:

299012 ÷ 8 = 37376 + R(4)
37376 ÷ 8 =   4672 + R(0)

4672 ÷ 8 =     584 + R(0)
584 ÷ 8 =       73 + R(0)
73 ÷ 8 =         9 + R(1)
9 ÷ 8 =         1 + R(1)
1 ÷ 8 =         0 + R(1)

The remainders will be the digits of Base 8 number. Use the digits of the remainders from bottom to top. Therefore,

299012 = 11100048
