We divide 869728 by 15
We're looking to find how many times 15 goes into 869728.

Going ahead to step 1:
If we divide 8 by 15, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 15

Step 2:
When dividing 86 by 15, we get 5 with a remainder of 11.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 75 from 86 leaves us with 11.
Grab the next digit (9) from the dividend, add it to 11, then carry on: 119 / 15

Step 3:
When dividing 119 by 15, we get 7 with a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 57.0
If we subtract 105 from 119, we get 14.
Include the next digit (7) from the dividend after 14, then repeat: 147 / 15

Advancing to step 4:
If we divide 147 by 15, we get 9 and a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 579.0
If we subtract 135 from 147, we get 12.
Bring next digit (2) of the dividend behind the 12 and repeat the process: 122 / 15

On to step 5:
The number 15 fits into 122 8 times, leaving a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 5798.0
Deduct 120 from 122 and we're left with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 15

Step 6:
The number 15 fits into 28 1 times, leaving a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 57981.0
If we take 15 away from 28, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
15 goes into 130 8 times with a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 57981.8
If we subtract 120 from 130, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
The number 15 fits into 100 6 times, leaving a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 57981.86
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
If we divide 100 by 15, we get 6 and a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 57981.866
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 57981.866 and a remainder of 0.001.
