We're dividing 81987510 by 871 
We want to divide 81987510 by 871.

Advancing to step 1:
871 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 871

Going ahead to step 2:
81 divided by 871 is 0 with a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Bring next digit (9) of the dividend behind the 81 and repeat the process: 819 / 871

Let's proceed to step 3:
When dividing 819 by 871, we get 0 with a remainder of 819.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 819, we get 819.
Bring next digit (8) of the dividend behind the 819 and repeat the process: 8198 / 871

Step 4:
If we divide 8198 by 871, we get 9 and a remainder of 359.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 7839 from 8198 leaves us with 359.
Fetch the next digit (7) from the dividend, attach it to 359 and continue: 3597 / 871

Advancing to step 5:
871 can be fit into 3597 4 times, resulting in a remainder of 113.
Record the quotient 4 as the next digit in the result. 
Result so far: 94.0
If we take 3484 away from 3597, we end up with 113.
Fetch the next digit (5) from the dividend, attach it to 113 and continue: 1135 / 871

Going ahead to step 6:
When dividing 1135 by 871, we get 1 with a remainder of 264.
Put 1 as the next digit of the answer. 
Result so far: 941.0
The remainder is 264 after subtracting 871 from 1135.
Include the next digit (1) from the dividend after 264, then repeat: 2641 / 871

Advancing to step 7:
871 can be fit into 2641 3 times, resulting in a remainder of 28.
The number 3 becomes the next digit in our result. 
Result so far: 9413.0
Subtracting 2613 from 2641 leaves us with 28.
Fetch the next digit (0) from the dividend, attach it to 28 and continue: 280 / 871

Moving on to step 8:
280 divided by 871 is 0 with a remainder of 280.
Write down 0 as next digit of the result. 
Result so far: 94130.0
Subtract 0 from 280 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 9:
871 goes into 2800 3 times with a remainder of 187.
Record the quotient 3 as the next digit in the result. 
Result so far: 94130.3
Subtracting 2613 from 2800 leaves us with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Going ahead to step 10:
When dividing 1870 by 871, we get 2 with a remainder of 128.
The number 2 becomes the next digit in our result. 
Result so far: 94130.32
If we subtract 1742 from 1870, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Step 11:
1280 divided by 871 is 1 with a remainder of 409.
Put 1 as the next digit of the answer. 
Result so far: 94130.321
The remainder is 409 after subtracting 871 from 1280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Step 12:
871 goes into 4090 4 times with a remainder of 606.
The number 4 becomes the next digit in our result. 
Result so far: 94130.3214
Deduct 3484 from 4090 and we're left with 606.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6060, and continue the process.

Advancing to step 13:
871 goes into 6060 6 times with a remainder of 834.
Record the quotient 6 as the next digit in the result. 
Result so far: 94130.32146
If we take 5226 away from 6060, we end up with 834.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8340, and continue the process.

On to step 14:
871 can be fit into 8340 9 times, resulting in a remainder of 501.
Write down 9 as next digit of the result. 
Result so far: 94130.321469
Subtracting 7839 from 8340 leaves us with 501.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5010, and continue the process.

Advancing to step 15:
871 can be fit into 5010 5 times, resulting in a remainder of 655.
Write down 5 as next digit of the result. 
Result so far: 94130.3214695
Subtracting 4355 from 5010 leaves us with 655.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6550, and continue the process.

Moving on to step 16:
6550 divided by 871 is 7 with a remainder of 453.
Write down 7 as next digit of the result. 
Result so far: 94130.32146957
If we subtract 6097 from 6550, we get 453.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4530, and continue the process.

After the division, we end up with 94130.32146957 and a remainder of 4.53e-07.
