Use 9 as the next digit of our solution. 
Result so far: 7289.809
The remainder is 44 after subtracting 756 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 10:
84 can be fit into 440 5 times, resulting in a remainder of 20.
The next digit of our result is 5. 
Result so far: 7289.8095
Deduct 420 from 440 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
84 goes into 200 2 times with a remainder of 32.
The next digit of our result is 2. 
Result so far: 7289.80952
If we take 168 away from 200, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 12:
The number 84 fits into 320 3 times, leaving a remainder of 68.
The next digit of our result is 3. 
Result so far: 7289.809523
Deduct 252 from 320 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 13:

The number 8 becomes the next digit in our result. 
Result so far: 7289.8095238
The remainder is 8 after subtracting 672 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 14:
80 divided by 84 is 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 7289.8095238
Deduct 0 from 80 and we're left with 80.
