We're dividing 865569 by 15 
Our goal is to divide 865569 by 15.

On to step 1:
8 divided by 15 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 15

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
Subtract 75 from 86 to get 11.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 15

Moving on to step 3:
115 divided by 15 is 7 with a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 57.0
The remainder is 10 after subtracting 105 from 115.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 15

Let's proceed to step 4:
15 goes into 105 7 times with a remainder of 0.
The next digit of our result is 7. 
Result so far: 577.0
If we take 105 away from 105, we end up with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 15

Let's proceed to step 5:
15 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 5770.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 15

Moving on to step 6:
The number 15 fits into 69 4 times, leaving a remainder of 9.
Use 4 as the next digit of our solution. 
Result so far: 57704.0
Subtract 60 from 69 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
15 goes into 90 6 times with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 57704.6
Subtracting 90 from 90 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.

Moving on to step 8:
If we divide 0 by 15, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 57704.6
If we subtract 0 from 0, we 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.

Going ahead to step 9:
The number 15 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 57704.6
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.

Our division results in 57704.6 with a remaining 0.0.
