We look at the division of 69972791 by 871 
Let's see how many times 871 fits into 69972791.

Advancing to step 1:
6 divided by 871 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 871

Let's proceed to step 2:
When dividing 69 by 871, we get 0 with a remainder of 69.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 69, we get 69.
Include the next digit (9) from the dividend after 69, then repeat: 699 / 871

Advancing to step 3:
When dividing 699 by 871, we get 0 with a remainder of 699.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 699 and we're left with 699.
Fetch the next digit (7) from the dividend, attach it to 699 and continue: 6997 / 871

Advancing to step 4:
871 goes into 6997 8 times with a remainder of 29.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 29 after subtracting 6968 from 6997.
Append the next digit (2) from the dividend to 29 and continue with: 292 / 871

Advancing to step 5:
The number 871 fits into 292 0 times, leaving a remainder of 292.
The number 0 becomes the next digit in our result. 
Result so far: 80.0
Subtract 0 from 292 to get 292.
Bring next digit (7) of the dividend behind the 292 and repeat the process: 2927 / 871

Moving on to step 6:
871 can be fit into 2927 3 times, resulting in a remainder of 314.
Use 3 as the next digit of our solution. 
Result so far: 803.0
The remainder is 314 after subtracting 2613 from 2927.
Take the next digit (9) from the dividend and append it to 314, then repeat: 3149 / 871

On to step 7:
The number 871 fits into 3149 3 times, leaving a remainder of 536.
The next digit of our result is 3. 
Result so far: 8033.0
If we take 2613 away from 3149, we end up with 536.
Fetch the next digit (1) from the dividend, attach it to 536 and continue: 5361 / 871

Step 8:
5361 divided by 871 is 6 with a remainder of 135.
Use 6 as the next digit of our solution. 
Result so far: 80336.0
If we take 5226 away from 5361, we end up with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Let's proceed to step 9:
871 can be fit into 1350 1 times, resulting in a remainder of 479.
Put 1 as the next digit of the answer. 
Result so far: 80336.1
If we take 871 away from 1350, we end up with 479.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

On to step 10:
871 can be fit into 4790 5 times, resulting in a remainder of 435.
Record the quotient 5 as the next digit in the result. 
Result so far: 80336.15
If we subtract 4355 from 4790, we get 435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Going ahead to step 11:
4350 divided by 871 is 4 with a remainder of 866.
The number 4 becomes the next digit in our result. 
Result so far: 80336.154
Subtract 3484 from 4350 to get 866.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8660, and continue the process.

Advancing to step 12:
871 goes into 8660 9 times with a remainder of 821.
Use 9 as the next digit of our solution. 
Result so far: 80336.1549
Subtract 7839 from 8660 to get 821.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8210, and continue the process.

Moving on to step 13:
The number 871 fits into 8210 9 times, leaving a remainder of 371.
Put 9 as the next digit of the answer. 
Result so far: 80336.15499
The remainder is 371 after subtracting 7839 from 8210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

The final result is 80336.15499 with a remainder of 0.000371.
