80 divided by 99 is 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 4351.08
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 10:
800 divided by 99 is 8 with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 4351.0808
Deduct 792 from 800 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
99 can be fit into 80 0 times, resulting in a remainder of 80.
The next digit of our result is 0. 
Result so far: 4351.0808
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 12:
If we divide 800 by 99, we get 8 and a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 4351.080808
The remainder is 8 after subtracting 792 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 13:
99 goes into 80 0 times with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 4351.080808
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 14:
When dividing 800 by 99, we get 8 with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 4351.08080808
Subtracting 792 from 800 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.
