Convert 195 from decimal to octal
(base 8) notation:
Raise our base of 8 to a power
Start at 0 and increasing by 1 until it is >= 195
80 = 1
81 = 8
82 = 64
83 = 512 <--- Stop: This is greater than 195
Since 512 is greater than 195, we use 1 power less as our starting point which equals 2
Work backwards from a power of 2
We start with a total sum of 0:
The highest coefficient less than 7 we can multiply this by to stay under 195 is 3
Multiplying this coefficient by our original value, we get: 3 * 64 = 192
Add our new value to our running total, we get:
0 + 192 = 192
This is <= 195, so we assign our outside coefficient of 3 for this digit.
Our new sum becomes 192
Our octal notation is now equal to 3
The highest coefficient less than 7 we can multiply this by to stay under 195 is 1
Multiplying this coefficient by our original value, we get: 1 * 8 = 8
Add our new value to our running total, we get:
192 + 8 = 200
This is > 195, so we assign a 0 for this digit.
Our total sum remains the same at 192
Our octal notation is now equal to 30
The highest coefficient less than 7 we can multiply this by to stay under 195 is 3
Multiplying this coefficient by our original value, we get: 3 * 1 = 3
Add our new value to our running total, we get:
192 + 3 = 195
This = 195, so we assign our outside coefficient of 3 for this digit.
Our new sum becomes 195
Our octal notation is now equal to 303
