Here, we want to use long division to find the result
We have this as follows;
We start by dividing 99 by 12
This gives 8 remainder 3
Now, as we all know, 3 cannot divide 12
So, what we do now is add zero at the back of 3 while we put a decimal point at the back of 8
Then we divide 30 by 12
This gives 2 remainder 6
Then finally, we add zero to the back of the 60 to leave us with 5
Thus, our answer is 8.25
