Let's divide 815385 by 15
We want to divide 815385 by 15.

Advancing to step 1:
15 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 15

Let's proceed to step 2:
15 can be fit into 81 5 times, resulting in a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 75 from 81 and we're left with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 15

Let's proceed to step 3:
65 divided by 15 is 4 with a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 54.0
The remainder is 5 after subtracting 60 from 65.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 15

On to step 4:
The number 15 fits into 53 3 times, leaving a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 543.0
If we subtract 45 from 53, we get 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 15

Moving on to step 5:
15 goes into 88 5 times with a remainder of 13.
The next digit of our result is 5. 
Result so far: 5435.0
If we subtract 75 from 88, we get 13.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 15

Step 6:
When dividing 135 by 15, we get 9 with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 54359.0
The remainder is 0 after subtracting 135 from 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
When dividing 0 by 15, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 54359.0
Deduct 0 from 0 and we're left 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:
15 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 54359.0
Subtract 0 from 0 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.

The final result is 54359.0 with a remainder of 0.0.
