We're dividing 871187 by 10 
We want to figure out the number of times 871187 can be divided by 10.

Let's proceed to step 1:
If we divide 8 by 10, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 10

Step 2:
10 goes into 87 8 times with a remainder of 7.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 7 after subtracting 80 from 87.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 10

Step 3:
10 goes into 71 7 times with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 87.0
The remainder is 1 after subtracting 70 from 71.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 10

Advancing to step 4:
11 divided by 10 is 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 871.0
If we subtract 10 from 11, we get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 10

Moving on to step 5:
18 divided by 10 is 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 8711.0
The remainder is 8 after subtracting 10 from 18.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 10

Advancing to step 6:
87 divided by 10 is 8 with a remainder of 7.
Record the quotient 8 as the next digit in the result. 
Result so far: 87118.0
Subtract 80 from 87 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 7:
If we divide 70 by 10, we get 7 and a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 87118.7
If we take 70 away from 70, we end up 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.

Advancing to step 8:
10 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 87118.7
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
10 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 87118.7
If we take 0 away from 0, we end up 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.

Our division results in 87118.7 with a remaining 0.0.
