We look at the division of 871787 by 15 
Our goal is to divide 871787 by 15.

Going ahead to step 1:
15 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 15

Going ahead to step 2:
15 can be fit into 87 5 times, resulting in a remainder of 12.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 75 from 87 leaves us with 12.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 15

On to step 3:
121 divided by 15 is 8 with a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 58.0
Deduct 120 from 121 and we're left with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 15

Going ahead to step 4:
If we divide 17 by 15, we get 1 and a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 581.0
Subtracting 15 from 17 leaves us with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 15

Step 5:
15 can be fit into 28 1 times, resulting in a remainder of 13.
The next digit of our result is 1. 
Result so far: 5811.0
Deduct 15 from 28 and we're left with 13.
Bring next digit (7) of the dividend behind the 13 and repeat the process: 137 / 15

Let's proceed to step 6:
137 divided by 15 is 9 with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 58119.0
The remainder is 2 after subtracting 135 from 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
15 goes into 20 1 times with a remainder of 5.
The next digit of our result is 1. 
Result so far: 58119.1
Subtract 15 from 20 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
15 goes into 50 3 times with a remainder of 5.
The next digit of our result is 3. 
Result so far: 58119.13
If we take 45 away from 50, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 9:
50 divided by 15 is 3 with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 58119.133
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

In conclusion, the division gives 58119.133 with a balance of 0.0005.
