We look at the division of 78249023 by 871 
Let's see how many times 871 fits into 78249023.

Step 1:
The number 871 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 871

Step 2:
If we divide 78 by 871, we get 0 and a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Include the next digit (2) from the dividend after 78, then repeat: 782 / 871

Let's proceed to step 3:
782 divided by 871 is 0 with a remainder of 782.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 782 to get 782.
Include the next digit (4) from the dividend after 782, then repeat: 7824 / 871

Let's proceed to step 4:
When dividing 7824 by 871, we get 8 with a remainder of 856.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 6968 from 7824 to get 856.
Bring next digit (9) of the dividend behind the 856 and repeat the process: 8569 / 871

Advancing to step 5:
If we divide 8569 by 871, we get 9 and a remainder of 730.
Use 9 as the next digit of our solution. 
Result so far: 89.0
Subtracting 7839 from 8569 leaves us with 730.
Bring next digit (0) of the dividend behind the 730 and repeat the process: 7300 / 871

Going ahead to step 6:
The number 871 fits into 7300 8 times, leaving a remainder of 332.
The next digit of our result is 8. 
Result so far: 898.0
If we take 6968 away from 7300, we end up with 332.
Grab the next digit (2) from the dividend, add it to 332, then carry on: 3322 / 871

Advancing to step 7:
3322 divided by 871 is 3 with a remainder of 709.
Put 3 as the next digit of the answer. 
Result so far: 8983.0
Deduct 2613 from 3322 and we're left with 709.
Append the next digit (3) from the dividend to 709 and continue with: 7093 / 871

Advancing to step 8:
When dividing 7093 by 871, we get 8 with a remainder of 125.
Put 8 as the next digit of the answer. 
Result so far: 89838.0
Deduct 6968 from 7093 and we're left with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

On to step 9:
If we divide 1250 by 871, we get 1 and a remainder of 379.
The number 1 becomes the next digit in our result. 
Result so far: 89838.1
Subtracting 871 from 1250 leaves us with 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

On to step 10:
3790 divided by 871 is 4 with a remainder of 306.
Put 4 as the next digit of the answer. 
Result so far: 89838.14
If we subtract 3484 from 3790, we get 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Step 11:
3060 divided by 871 is 3 with a remainder of 447.
The number 3 becomes the next digit in our result. 
Result so far: 89838.143
Subtract 2613 from 3060 to get 447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

Going ahead to step 12:
871 can be fit into 4470 5 times, resulting in a remainder of 115.
Record the quotient 5 as the next digit in the result. 
Result so far: 89838.1435
The remainder is 115 after subtracting 4355 from 4470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Moving on to step 13:
1150 divided by 871 is 1 with a remainder of 279.
Record the quotient 1 as the next digit in the result. 
Result so far: 89838.14351
If we subtract 871 from 1150, we get 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Moving on to step 14:
When dividing 2790 by 871, we get 3 with a remainder of 177.
Use 3 as the next digit of our solution. 
Result so far: 89838.143513
The remainder is 177 after subtracting 2613 from 2790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Advancing to step 15:
The number 871 fits into 1770 2 times, leaving a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 89838.1435132
Subtracting 1742 from 1770 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 16:
When dividing 280 by 871, we get 0 with a remainder of 280.
Record the quotient 0 as the next digit in the result. 
Result so far: 89838.1435132
Deduct 0 from 280 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

After the division, we end up with 89838.1435132 and a remainder of 2.8e-07.
