Let's divide 809565 by 15
We want to figure out the number of times 809565 can be divided by 15.

Moving on to step 1:
8 divided by 15 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 15

Moving on to step 2:
If we divide 80 by 15, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we subtract 75 from 80, we get 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 15

On to step 3:
15 goes into 59 3 times with a remainder of 14.
The number 3 becomes the next digit in our result. 
Result so far: 53.0
Subtract 45 from 59 to get 14.
Append the next digit (5) from the dividend to 14 and continue with: 145 / 15

Let's proceed to step 4:
15 can be fit into 145 9 times, resulting in a remainder of 10.
Put 9 as the next digit of the answer. 
Result so far: 539.0
Subtract 135 from 145 to get 10.
Take the next digit (6) from the dividend and append it to 10, then repeat: 106 / 15

Let's proceed to step 5:
15 goes into 106 7 times with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 5397.0
If we subtract 105 from 106, we get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 15

Going ahead to step 6:
When dividing 15 by 15, we get 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 53971.0
If we take 15 away from 15, we end up 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 7:
15 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 53971.0
If we take 0 away from 0, we end up 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 8:
The number 15 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 53971.0
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.

In conclusion, the division gives 53971.0 with a balance of 0.0.
