We look at the division of 71871521 by 842 
We want to divide 71871521 by 842.

Advancing to step 1:
If we divide 7 by 842, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 842

Going ahead to step 2:
When dividing 71 by 842, we get 0 with a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 71 after subtracting 0 from 71.
Include the next digit (8) from the dividend after 71, then repeat: 718 / 842

Moving on to step 3:
842 can be fit into 718 0 times, resulting in a remainder of 718.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 718, we get 718.
Append the next digit (7) from the dividend to 718 and continue with: 7187 / 842

Step 4:
When dividing 7187 by 842, we get 8 with a remainder of 451.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 6736 away from 7187, we end up with 451.
Bring next digit (1) of the dividend behind the 451 and repeat the process: 4511 / 842

Going ahead to step 5:
The number 842 fits into 4511 5 times, leaving a remainder of 301.
Put 5 as the next digit of the answer. 
Result so far: 85.0
Subtract 4210 from 4511 to get 301.
Take the next digit (5) from the dividend and append it to 301, then repeat: 3015 / 842

Step 6:
842 goes into 3015 3 times with a remainder of 489.
The next digit of our result is 3. 
Result so far: 853.0
The remainder is 489 after subtracting 2526 from 3015.
Grab the next digit (2) from the dividend, add it to 489, then carry on: 4892 / 842

Going ahead to step 7:
If we divide 4892 by 842, we get 5 and a remainder of 682.
Use 5 as the next digit of our solution. 
Result so far: 8535.0
Subtracting 4210 from 4892 leaves us with 682.
Append the next digit (1) from the dividend to 682 and continue with: 6821 / 842

On to step 8:
When dividing 6821 by 842, we get 8 with a remainder of 85.
The number 8 becomes the next digit in our result. 
Result so far: 85358.0
Subtract 6736 from 6821 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 9:
842 can be fit into 850 1 times, resulting in a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 85358.1
Subtracting 842 from 850 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
842 goes into 80 0 times with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 85358.1
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 11:
842 can be fit into 800 0 times, resulting in a remainder of 800.
The number 0 becomes the next digit in our result. 
Result so far: 85358.1
Subtracting 0 from 800 leaves us with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Our division results in 85358.1 with a remaining 0.08.
