We look at the division of 86721180 by 997 
We're looking to find how many times 997 goes into 86721180.

Going ahead to step 1:
When dividing 8 by 997, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 997

Moving on to step 2:
997 goes into 86 0 times with a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Include the next digit (7) from the dividend after 86, then repeat: 867 / 997

Let's proceed to step 3:
997 can be fit into 867 0 times, resulting in a remainder of 867.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 867 and we're left with 867.
Append the next digit (2) from the dividend to 867 and continue with: 8672 / 997

On to step 4:
The number 997 fits into 8672 8 times, leaving a remainder of 696.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 7976 from 8672 to get 696.
Fetch the next digit (1) from the dividend, attach it to 696 and continue: 6961 / 997

On to step 5:
If we divide 6961 by 997, we get 6 and a remainder of 979.
The number 6 becomes the next digit in our result. 
Result so far: 86.0
If we take 5982 away from 6961, we end up with 979.
Take the next digit (1) from the dividend and append it to 979, then repeat: 9791 / 997

On to step 6:
When dividing 9791 by 997, we get 9 with a remainder of 818.
Use 9 as the next digit of our solution. 
Result so far: 869.0
If we subtract 8973 from 9791, we get 818.
Take the next digit (8) from the dividend and append it to 818, then repeat: 8188 / 997

Going ahead to step 7:
The number 997 fits into 8188 8 times, leaving a remainder of 212.
Write down 8 as next digit of the result. 
Result so far: 8698.0
If we take 7976 away from 8188, we end up with 212.
Fetch the next digit (0) from the dividend, attach it to 212 and continue: 2120 / 997

Moving on to step 8:
997 goes into 2120 2 times with a remainder of 126.
Write down 2 as next digit of the result. 
Result so far: 86982.0
If we take 1994 away from 2120, we end up with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

On to step 9:
997 goes into 1260 1 times with a remainder of 263.
The number 1 becomes the next digit in our result. 
Result so far: 86982.1
If we subtract 997 from 1260, we get 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Advancing to step 10:
2630 divided by 997 is 2 with a remainder of 636.
Put 2 as the next digit of the answer. 
Result so far: 86982.12
Subtracting 1994 from 2630 leaves us with 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Advancing to step 11:
The number 997 fits into 6360 6 times, leaving a remainder of 378.
The number 6 becomes the next digit in our result. 
Result so far: 86982.126
The remainder is 378 after subtracting 5982 from 6360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

On to step 12:
997 can be fit into 3780 3 times, resulting in a remainder of 789.
Record the quotient 3 as the next digit in the result. 
Result so far: 86982.1263
If we subtract 2991 from 3780, we get 789.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7890, and continue the process.

Advancing to step 13:
997 can be fit into 7890 7 times, resulting in a remainder of 911.
Write down 7 as next digit of the result. 
Result so far: 86982.12637
Subtract 6979 from 7890 to get 911.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9110, and continue the process.

On to step 14:
The number 997 fits into 9110 9 times, leaving a remainder of 137.
The next digit of our result is 9. 
Result so far: 86982.126379
If we subtract 8973 from 9110, we get 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Moving on to step 15:
When dividing 1370 by 997, we get 1 with a remainder of 373.
Write down 1 as next digit of the result. 
Result so far: 86982.1263791
If we take 997 away from 1370, we end up with 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Advancing to step 16:
3730 divided by 997 is 3 with a remainder of 739.
Write down 3 as next digit of the result. 
Result so far: 86982.12637913
If we subtract 2991 from 3730, we get 739.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7390, and continue the process.

The final outcome is 86982.12637913, with a leftover of 7.39e-07.
