Let's divide 79815959 by 871
We're looking to find how many times 871 goes into 79815959.

On to step 1:
871 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 871

Advancing to step 2:
871 goes into 79 0 times with a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 79 after subtracting 0 from 79.
Append the next digit (8) from the dividend to 79 and continue with: 798 / 871

On to step 3:
798 divided by 871 is 0 with a remainder of 798.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 798, we get 798.
Take the next digit (1) from the dividend and append it to 798, then repeat: 7981 / 871

Step 4:
The number 871 fits into 7981 9 times, leaving a remainder of 142.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 7839 from 7981 and we're left with 142.
Include the next digit (5) from the dividend after 142, then repeat: 1425 / 871

Going ahead to step 5:
871 can be fit into 1425 1 times, resulting in a remainder of 554.
Put 1 as the next digit of the answer. 
Result so far: 91.0
Deduct 871 from 1425 and we're left with 554.
Include the next digit (9) from the dividend after 554, then repeat: 5549 / 871

Moving on to step 6:
871 goes into 5549 6 times with a remainder of 323.
Use 6 as the next digit of our solution. 
Result so far: 916.0
The remainder is 323 after subtracting 5226 from 5549.
Fetch the next digit (5) from the dividend, attach it to 323 and continue: 3235 / 871

Advancing to step 7:
871 goes into 3235 3 times with a remainder of 622.
The number 3 becomes the next digit in our result. 
Result so far: 9163.0
Subtract 2613 from 3235 to get 622.
Take the next digit (9) from the dividend and append it to 622, then repeat: 6229 / 871

Step 8:
871 can be fit into 6229 7 times, resulting in a remainder of 132.
Record the quotient 7 as the next digit in the result. 
Result so far: 91637.0
Deduct 6097 from 6229 and we're left with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Let's proceed to step 9:
1320 divided by 871 is 1 with a remainder of 449.
The number 1 becomes the next digit in our result. 
Result so far: 91637.1
If we subtract 871 from 1320, we get 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

Let's proceed to step 10:
4490 divided by 871 is 5 with a remainder of 135.
Write down 5 as next digit of the result. 
Result so far: 91637.15
If we subtract 4355 from 4490, we get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Moving on to step 11:
When dividing 1350 by 871, we get 1 with a remainder of 479.
The next digit of our result is 1. 
Result so far: 91637.151
The remainder is 479 after subtracting 871 from 1350.
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 12:
871 goes into 4790 5 times with a remainder of 435.
Use 5 as the next digit of our solution. 
Result so far: 91637.1515
The remainder is 435 after subtracting 4355 from 4790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4350, and continue the process.

Advancing to step 13:
871 goes into 4350 4 times with a remainder of 866.
Use 4 as the next digit of our solution. 
Result so far: 91637.15154
If we subtract 3484 from 4350, we 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 14:
871 goes into 8660 9 times with a remainder of 821.
The next digit of our result is 9. 
Result so far: 91637.151549
If we take 7839 away from 8660, we end up with 821.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8210, and continue the process.

Advancing to step 15:
8210 divided by 871 is 9 with a remainder of 371.
Put 9 as the next digit of the answer. 
Result so far: 91637.1515499
Subtracting 7839 from 8210 leaves us with 371.
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 91637.1515499 with a remainder of 3.71e-06.
