The next digit of our result is 8. 
Result so far: 13323.378
Subtract 528 from 580 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 10:
The number 66 fits into 520 7 times, leaving a remainder of 58.
Put 7 as the next digit of the answer. 
Result so far: 13323.3787
Subtracting 462 from 520 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 11:
If we divide 580 by 66, we get 8 and a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 13323.37878
Subtracting 528 from 580 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 12:
520 divided by 66 is 7 with a remainder of 58.
Use 7 as the next digit of our solution. 
Result so far: 13323.378787
The remainder is 58 after subtracting 462 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 13:
The number 66 fits into 580 8 times, leaving a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 13323.3787878
