Write down 1 as next digit of the result. 
Result so far: 3205.141
The remainder is 41 after subtracting 99 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 10:
If we divide 410 by 99, we get 4 and a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 3205.1414
The remainder is 14 after subtracting 396 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 11:
140 divided by 99 is 1 with a remainder of 41.
Record the quotient 1 as the next digit in the result. 
Result so far: 3205.14141
If we subtract 99 from 140, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 12:
If we divide 410 by 99, we get 4 and a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 3205.141414
Subtract 396 from 410 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 13:
When dividing 140 by 99, we get 1 with a remainder of 41.
The next digit of our result is 1. 
Result so far: 3205.1414141
Subtracting 99 from 140 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 14:
410 divided by 99 is 4 with a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 3205.14141414
Deduct 396 from 410 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.
