We're dividing 831504 by 15 
We want to divide 831504 by 15.

Advancing to step 1:
If we divide 8 by 15, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 15

Moving on to step 2:
15 can be fit into 83 5 times, resulting in a remainder of 8.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 75 from 83 leaves us with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 15

Advancing to step 3:
If we divide 81 by 15, we get 5 and a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 55.0
If we subtract 75 from 81, we get 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 15

On to step 4:
The number 15 fits into 65 4 times, leaving a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 554.0
Subtracting 60 from 65 leaves us with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 15

Going ahead to step 5:
The number 15 fits into 50 3 times, leaving a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 5543.0
If we take 45 away from 50, we end up with 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 15

On to step 6:
15 goes into 54 3 times with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 55433.0
If we take 45 away from 54, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
When dividing 90 by 15, we get 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 55433.6
If we subtract 90 from 90, 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.

Let's proceed to step 8:
When dividing 0 by 15, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 55433.6
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 9:
If we divide 0 by 15, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 55433.6
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.

Our division results in 55433.6 with a remaining 0.0.
