We're dividing 81636015 by 997 
We're looking to find how many times 997 goes into 81636015.

Step 1:
8 divided by 997 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 997

On to step 2:
If we divide 81 by 997, we get 0 and a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Bring next digit (6) of the dividend behind the 81 and repeat the process: 816 / 997

Going ahead to step 3:
997 goes into 816 0 times with a remainder of 816.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 816 to get 816.
Bring next digit (3) of the dividend behind the 816 and repeat the process: 8163 / 997

Step 4:
997 goes into 8163 8 times with a remainder of 187.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 7976 from 8163 leaves us with 187.
Bring next digit (6) of the dividend behind the 187 and repeat the process: 1876 / 997

On to step 5:
When dividing 1876 by 997, we get 1 with a remainder of 879.
The next digit of our result is 1. 
Result so far: 81.0
Deduct 997 from 1876 and we're left with 879.
Bring next digit (0) of the dividend behind the 879 and repeat the process: 8790 / 997

Advancing to step 6:
When dividing 8790 by 997, we get 8 with a remainder of 814.
Put 8 as the next digit of the answer. 
Result so far: 818.0
The remainder is 814 after subtracting 7976 from 8790.
Fetch the next digit (1) from the dividend, attach it to 814 and continue: 8141 / 997

Let's proceed to step 7:
997 goes into 8141 8 times with a remainder of 165.
Use 8 as the next digit of our solution. 
Result so far: 8188.0
Deduct 7976 from 8141 and we're left with 165.
Take the next digit (5) from the dividend and append it to 165, then repeat: 1655 / 997

Moving on to step 8:
1655 divided by 997 is 1 with a remainder of 658.
The next digit of our result is 1. 
Result so far: 81881.0
Subtracting 997 from 1655 leaves us with 658.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6580, and continue the process.

Step 9:
997 goes into 6580 6 times with a remainder of 598.
The number 6 becomes the next digit in our result. 
Result so far: 81881.6
If we subtract 5982 from 6580, we get 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

Going ahead to step 10:
When dividing 5980 by 997, we get 5 with a remainder of 995.
Write down 5 as next digit of the result. 
Result so far: 81881.65
If we subtract 4985 from 5980, we get 995.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9950, and continue the process.

Going ahead to step 11:
997 goes into 9950 9 times with a remainder of 977.
Write down 9 as next digit of the result. 
Result so far: 81881.659
Deduct 8973 from 9950 and we're left with 977.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9770, and continue the process.

Advancing to step 12:
If we divide 9770 by 997, we get 9 and a remainder of 797.
The next digit of our result is 9. 
Result so far: 81881.6599
Subtract 8973 from 9770 to get 797.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7970, and continue the process.

The final result is 81881.6599 with a remainder of 0.00797.
