We're dividing 864837 by 15 
We want to figure out the number of times 864837 can be divided by 15.

On to step 1:
The number 15 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 15

Moving on to step 2:
15 can be fit into 86 5 times, resulting in a remainder of 11.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 11 after subtracting 75 from 86.
Bring next digit (4) of the dividend behind the 11 and repeat the process: 114 / 15

Let's proceed to step 3:
114 divided by 15 is 7 with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 57.0
If we take 105 away from 114, we end up with 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 15

Step 4:
If we divide 98 by 15, we get 6 and a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 576.0
Deduct 90 from 98 and we're left with 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 15

On to step 5:
When dividing 83 by 15, we get 5 with a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 5765.0
Subtract 75 from 83 to get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 15

Advancing to step 6:
If we divide 87 by 15, we get 5 and a remainder of 12.
The next digit of our result is 5. 
Result so far: 57655.0
Subtracting 75 from 87 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 7:
If we divide 120 by 15, we get 8 and a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 57655.8
Subtract 120 from 120 to 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.

Step 8:
The number 15 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 57655.8
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.

Let's proceed to step 9:
15 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 57655.8
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.

In conclusion, the division gives 57655.8 with a balance of 0.0.
