We're dividing 81957818 by 993 
We're looking to find how many times 993 goes into 81957818.

Step 1:
When dividing 8 by 993, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 993

Step 2:
If we divide 81 by 993, we get 0 and a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Append the next digit (9) from the dividend to 81 and continue with: 819 / 993

Moving on to step 3:
819 divided by 993 is 0 with a remainder of 819.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 819 after subtracting 0 from 819.
Take the next digit (5) from the dividend and append it to 819, then repeat: 8195 / 993

Advancing to step 4:
The number 993 fits into 8195 8 times, leaving a remainder of 251.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 7944 away from 8195, we end up with 251.
Bring next digit (7) of the dividend behind the 251 and repeat the process: 2517 / 993

Step 5:
The number 993 fits into 2517 2 times, leaving a remainder of 531.
Put 2 as the next digit of the answer. 
Result so far: 82.0
The remainder is 531 after subtracting 1986 from 2517.
Bring next digit (8) of the dividend behind the 531 and repeat the process: 5318 / 993

Moving on to step 6:
5318 divided by 993 is 5 with a remainder of 353.
The next digit of our result is 5. 
Result so far: 825.0
If we subtract 4965 from 5318, we get 353.
Append the next digit (1) from the dividend to 353 and continue with: 3531 / 993

Moving on to step 7:
If we divide 3531 by 993, we get 3 and a remainder of 552.
Use 3 as the next digit of our solution. 
Result so far: 8253.0
If we take 2979 away from 3531, we end up with 552.
Bring next digit (8) of the dividend behind the 552 and repeat the process: 5528 / 993

Going ahead to step 8:
If we divide 5528 by 993, we get 5 and a remainder of 563.
Write down 5 as next digit of the result. 
Result so far: 82535.0
If we take 4965 away from 5528, we end up with 563.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5630, and continue the process.

Let's proceed to step 9:
If we divide 5630 by 993, we get 5 and a remainder of 665.
Use 5 as the next digit of our solution. 
Result so far: 82535.5
If we subtract 4965 from 5630, we get 665.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6650, and continue the process.

Let's proceed to step 10:
6650 divided by 993 is 6 with a remainder of 692.
The number 6 becomes the next digit in our result. 
Result so far: 82535.56
Subtracting 5958 from 6650 leaves us with 692.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6920, and continue the process.

Going ahead to step 11:
993 can be fit into 6920 6 times, resulting in a remainder of 962.
The next digit of our result is 6. 
Result so far: 82535.566
If we subtract 5958 from 6920, we get 962.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9620, and continue the process.

After the division, we end up with 82535.566 and a remainder of 0.0962.
