Denary to Octal : Sum of Place Values

[B]   Sum of PVs   Chain
Example: Convert the denary number 13351 to octal.

4096 512 64 8 1

For each column from left to right:				13351
Find how many times the weighting		3x4096 =		-12288
is included in the denary number.				1063
That number is the octal digit		2x512 =		-1024
1, 2, ..., 7 for that column.				39
Subtract that number of weightings		0x64 =		-0
from the denary number.				39
		4x8 =		-32
				7
		7x1 =		-7
The complete octal number is:		32047		0
