993 can be fit into 6604 6 times, resulting in a remainder of 646.
The next digit of our result is 6. 
Result so far: 16.0
The remainder is 646 after subtracting 5958 from 6604.
Bring next digit (4) of the dividend behind the 646 and repeat the process: 6464 / 993

Moving on to step 6:
6464 divided by 993 is 6 with a remainder of 506.
Use 6 as the next digit of our solution. 
Result so far: 166.0
If we take 5958 away from 6464, we end up with 506.
Fetch the next digit (1) from the dividend, attach it to 506 and continue: 5061 / 993

Step 7:
5061 divided by 993 is 5 with a remainder of 96.
Put 5 as the next digit of the answer. 
Result so far: 1665.0
The remainder is 96 after subtracting 4965 from 5061.
Bring next digit (9) of the dividend behind the 96 and repeat the process: 969 / 993

Advancing to step 8:
993 goes into 969 0 times with a remainder of 969.
Use 0 as the next digit of our solution. 
Result so far: 16650.0
If we subtract 0 from 969, we get 969.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9690, and continue the process.

Moving on to step 9:
993 can be fit into 9690 9 times, resulting in a remainder of 753.
The next digit of our result is 9. 
Result so far: 16650.9
Subtract 8937 from 9690 to get 753.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7530, and continue the process.

Let's proceed to step 10:
When dividing 7530 by 993, we get 7 with a remainder of 579.
Write down 7 as next digit of the result. 
Result so far: 16650.97
Deduct 6951 from 7530 and we're left with 579.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5790, and continue the process.

Going ahead to step 11:
993 can be fit into 5790 5 times, resulting in a remainder of 825.
The next digit of our result is 5. 
Result so far: 16650.975
If we take 4965 away from 5790, we end up with 825.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8250, and continue the process.

Let's proceed to step 12:
993 can be fit into 8250 8 times, resulting in a remainder of 306.
The number 8 becomes the next digit in our result. 
Result so far: 16650.9758
Subtract 7944 from 8250 to get 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Going ahead to step 13:
When dividing 3060 by 993, we get 3 with a remainder of 81.
The next digit of our result is 3. 
Result so far: 16650.97583
Subtract 2979 from 3060 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 14:
993 can be fit into 810 0 times, resulting in a remainder of 810.
The number 0 becomes the next digit in our result. 
Result so far: 16650.97583
If we subtract 0 from 810, we get 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

Moving on to step 15:
The number 993 fits into 8100 8 times, leaving a remainder of 156.
The number 8 becomes the next digit in our result. 
Result so far: 16650.9758308
The remainder is 156 after subtracting 7944 from 8100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Advancing to step 16:
993 goes into 1560 1 times with a remainder of 567.
The next digit of our result is 1. 
Result so far: 16650.97583081
If we take 993 away from 1560, we end up with 567.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5670, and continue the process.

The final result is 16650.97583081 with a remainder of 5.67e-07.
