We're dividing 86104847 by 15 
We want to divide 86104847 by 15.

Advancing to step 1:
The number 15 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 15

Advancing to step 2:
The number 15 fits into 86 5 times, leaving a remainder of 11.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 75 from 86, we get 11.
Include the next digit (1) from the dividend after 11, then repeat: 111 / 15

On to step 3:
15 can be fit into 111 7 times, resulting in a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 57.0
Deduct 105 from 111 and we're left with 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 15

On to step 4:
15 can be fit into 60 4 times, resulting in a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 574.0
If we take 60 away from 60, we end up with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 15

Advancing to step 5:
4 divided by 15 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 5740.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 15

Let's proceed to step 6:
When dividing 48 by 15, we get 3 with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 57403.0
Subtracting 45 from 48 leaves us with 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 15

Moving on to step 7:
34 divided by 15 is 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 574032.0
Subtracting 30 from 34 leaves us with 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 15

Advancing to step 8:
If we divide 47 by 15, we get 3 and a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 5740323.0
If we subtract 45 from 47, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 9:
The number 15 fits into 20 1 times, leaving a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 5740323.1
Deduct 15 from 20 and we're left 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 10:
50 divided by 15 is 3 with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 5740323.13
Deduct 45 from 50 and we're left 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 11:
The number 15 fits into 50 3 times, leaving a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 5740323.133
Subtract 45 from 50 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.

In conclusion, the division gives 5740323.133 with a balance of 0.0005.
