We look at the division of 71512910 by 811 
We want to figure out the number of times 71512910 can be divided by 811.

Advancing to step 1:
When dividing 7 by 811, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 811

Going ahead to step 2:
If we divide 71 by 811, we get 0 and a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Bring next digit (5) of the dividend behind the 71 and repeat the process: 715 / 811

Advancing to step 3:
The number 811 fits into 715 0 times, leaving a remainder of 715.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 715, we end up with 715.
Take the next digit (1) from the dividend and append it to 715, then repeat: 7151 / 811

On to step 4:
If we divide 7151 by 811, we get 8 and a remainder of 663.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 6488 from 7151 to get 663.
Include the next digit (2) from the dividend after 663, then repeat: 6632 / 811

Step 5:
The number 811 fits into 6632 8 times, leaving a remainder of 144.
Use 8 as the next digit of our solution. 
Result so far: 88.0
The remainder is 144 after subtracting 6488 from 6632.
Grab the next digit (9) from the dividend, add it to 144, then carry on: 1449 / 811

Moving on to step 6:
When dividing 1449 by 811, we get 1 with a remainder of 638.
The next digit of our result is 1. 
Result so far: 881.0
If we take 811 away from 1449, we end up with 638.
Bring next digit (1) of the dividend behind the 638 and repeat the process: 6381 / 811

Moving on to step 7:
6381 divided by 811 is 7 with a remainder of 704.
The number 7 becomes the next digit in our result. 
Result so far: 8817.0
Deduct 5677 from 6381 and we're left with 704.
Bring next digit (0) of the dividend behind the 704 and repeat the process: 7040 / 811

Let's proceed to step 8:
811 goes into 7040 8 times with a remainder of 552.
Use 8 as the next digit of our solution. 
Result so far: 88178.0
Subtracting 6488 from 7040 leaves us with 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Advancing to step 9:
When dividing 5520 by 811, we get 6 with a remainder of 654.
Record the quotient 6 as the next digit in the result. 
Result so far: 88178.6
The remainder is 654 after subtracting 4866 from 5520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6540, and continue the process.

Going ahead to step 10:
811 can be fit into 6540 8 times, resulting in a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 88178.68
If we subtract 6488 from 6540, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 11:
520 divided by 811 is 0 with a remainder of 520.
The next digit of our result is 0. 
Result so far: 88178.68
Deduct 0 from 520 and we're left with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 12:
If we divide 5200 by 811, we get 6 and a remainder of 334.
The next digit of our result is 6. 
Result so far: 88178.6806
The remainder is 334 after subtracting 4866 from 5200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Let's proceed to step 13:
811 can be fit into 3340 4 times, resulting in a remainder of 96.
The next digit of our result is 4. 
Result so far: 88178.68064
Subtracting 3244 from 3340 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 14:
The number 811 fits into 960 1 times, leaving a remainder of 149.
Use 1 as the next digit of our solution. 
Result so far: 88178.680641
Subtract 811 from 960 to get 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

Advancing to step 15:
811 goes into 1490 1 times with a remainder of 679.
The next digit of our result is 1. 
Result so far: 88178.6806411
Subtract 811 from 1490 to get 679.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6790, and continue the process.

The final outcome is 88178.6806411, with a leftover of 6.79e-06.
