Therefore 758 - 111101 which is the same pattern of 1's & 0's as we
got from converting from base 10 to base 2. What this really says that it is
easier to convert any base 10 number to base 8 by continuous division, and
then convert each digit of the base 8 number to base 2.
Let's look at another example. Convert 18310 to base 8 & to base 2.

2678 = 7x8
0 + 6x81 + 2x82
= 7x1 + 6x8 + 2x64
= 7 + 48 + 128
= 183
to convert 2678 directly to base 2, we convert each base 8 digit
separately.
