We look at the division of 81973876 by 797 
We want to divide 81973876 by 797.

Let's proceed to step 1:
If we divide 8 by 797, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 797

Going ahead to step 2:
797 can be fit into 81 0 times, resulting in a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Include the next digit (9) from the dividend after 81, then repeat: 819 / 797

Step 3:
If we divide 819 by 797, we get 1 and a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 797 from 819 leaves us with 22.
Bring next digit (7) of the dividend behind the 22 and repeat the process: 227 / 797

Moving on to step 4:
When dividing 227 by 797, we get 0 with a remainder of 227.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 227 leaves us with 227.
Fetch the next digit (3) from the dividend, attach it to 227 and continue: 2273 / 797

Moving on to step 5:
The number 797 fits into 2273 2 times, leaving a remainder of 679.
Use 2 as the next digit of our solution. 
Result so far: 102.0
The remainder is 679 after subtracting 1594 from 2273.
Bring next digit (8) of the dividend behind the 679 and repeat the process: 6798 / 797

On to step 6:
When dividing 6798 by 797, we get 8 with a remainder of 422.
Use 8 as the next digit of our solution. 
Result so far: 1028.0
If we subtract 6376 from 6798, we get 422.
Fetch the next digit (7) from the dividend, attach it to 422 and continue: 4227 / 797

Moving on to step 7:
If we divide 4227 by 797, we get 5 and a remainder of 242.
Record the quotient 5 as the next digit in the result. 
Result so far: 10285.0
Subtracting 3985 from 4227 leaves us with 242.
Bring next digit (6) of the dividend behind the 242 and repeat the process: 2426 / 797

On to step 8:
When dividing 2426 by 797, we get 3 with a remainder of 35.
Record the quotient 3 as the next digit in the result. 
Result so far: 102853.0
The remainder is 35 after subtracting 2391 from 2426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 9:
When dividing 350 by 797, we get 0 with a remainder of 350.
Write down 0 as next digit of the result. 
Result so far: 102853.0
The remainder is 350 after subtracting 0 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Step 10:
797 goes into 3500 4 times with a remainder of 312.
Put 4 as the next digit of the answer. 
Result so far: 102853.04
If we subtract 3188 from 3500, we get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Step 11:
If we divide 3120 by 797, we get 3 and a remainder of 729.
Use 3 as the next digit of our solution. 
Result so far: 102853.043
If we subtract 2391 from 3120, we get 729.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7290, and continue the process.

Going ahead to step 12:
The number 797 fits into 7290 9 times, leaving a remainder of 117.
Put 9 as the next digit of the answer. 
Result so far: 102853.0439
Deduct 7173 from 7290 and we're left with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Moving on to step 13:
1170 divided by 797 is 1 with a remainder of 373.
Put 1 as the next digit of the answer. 
Result so far: 102853.04391
If we subtract 797 from 1170, we get 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

On to step 14:
If we divide 3730 by 797, we get 4 and a remainder of 542.
Write down 4 as next digit of the result. 
Result so far: 102853.043914
If we subtract 3188 from 3730, we get 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

Step 15:
797 goes into 5420 6 times with a remainder of 638.
The next digit of our result is 6. 
Result so far: 102853.0439146
If we subtract 4782 from 5420, we get 638.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

Going ahead to step 16:
797 goes into 6380 8 times with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 102853.04391468
If we take 6376 away from 6380, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 102853.04391468, with a leftover of 4e-09.
