99871 ÷ 10 
We're looking to find how many times 10 goes into 99871.

Moving on to step 1:
10 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 10

Moving on to step 2:
99 divided by 10 is 9 with a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 90 from 99 leaves us with 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 10

Going ahead to step 3:
If we divide 98 by 10, we get 9 and a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 99.0
Deduct 90 from 98 and we're left with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 10

Going ahead to step 4:
87 divided by 10 is 8 with a remainder of 7.
Use 8 as the next digit of our solution. 
Result so far: 998.0
Subtract 80 from 87 to get 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 10

Let's proceed to step 5:
71 divided by 10 is 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 9987.0
If we take 70 away from 71, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 6:
When dividing 10 by 10, we get 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 9987.1
If we subtract 10 from 10, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
0 divided by 10 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 9987.1
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
If we divide 0 by 10, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 9987.1
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 9987.1, and the remainder is 0.0.
