To convert from binary to octal: take the first three entries immediately to the right and include the
20 term in the binary expansion; this may be considered as a three-digit binary number; convert this
number into octal; the resulting octal number is the 80 term of the octal expansion. Now do the same
with the next three digits of the binary expansion to get the 81 term of the octal expansion, and so on.

1012 = 58, 1002 = 48, 0112 = 38, and 12 = 18 so

The rule works in this case as well: 1002 = 48, 1102 = 68, 0112 = 38 and 0012 = 18.
