Put 9 as the next digit of the answer. 
Result so far: 50439.0
Subtract 8937 from 9756 to get 819.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8190, and continue the process.

Advancing to step 9:
The number 993 fits into 8190 8 times, leaving a remainder of 246.
Put 8 as the next digit of the answer. 
Result so far: 50439.8
Subtracting 7944 from 8190 leaves us with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Step 10:
2460 divided by 993 is 2 with a remainder of 474.
Write down 2 as next digit of the result. 
Result so far: 50439.82
Deduct 1986 from 2460 and we're left with 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Step 11:
If we divide 4740 by 993, we get 4 and a remainder of 768.
The next digit of our result is 4. 
Result so far: 50439.824
Deduct 3972 from 4740 and we're left with 768.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7680, and continue the process.

Advancing to step 12:
If we divide 7680 by 993, we get 7 and a remainder of 729.
Record the quotient 7 as the next digit in the result. 
Result so far: 50439.8247
Subtracting 6951 from 7680 leaves us with 729.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7290, and continue the process.

Advancing to step 13:
When dividing 7290 by 993, we get 7 with a remainder of 339.
Write down 7 as next digit of the result. 
Result so far: 50439.82477
Deduct 6951 from 7290 and we're left with 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

The final result is 50439.82477 with a remainder of 0.000339.
