Convert 8 from decimal to octal

(base 8) notation:

##### Power Test

Raise our base of 8 to a power

Start at 0 and increasing by 1 until it is >= 8

80 = 1

81 = 8 <--- Stop: This is equal to 8

Since 8 is equal to 8, we use our current power as our starting point which equals 1

##### Build octal notation

Work backwards from a power of 1

##### 81 = 8

The highest coefficient less than 7 we can multiply this by to stay under 8 is 1

Multiplying this coefficient by our original value, we get: 1 * 8 = 8

Add our new value to our running total, we get:
0 + 8 = 8

This = 8, so we assign our outside coefficient of 1 for this digit.

Our new sum becomes 8

Our octal notation is now equal to 1

##### 80 = 1

The highest coefficient less than 7 we can multiply this by to stay under 8 is 1

Multiplying this coefficient by our original value, we get: 1 * 1 = 1

Add our new value to our running total, we get:
8 + 1 = 9

This is > 8, so we assign a 0 for this digit.

Our total sum remains the same at 8

Our octal notation is now equal to 10
