Let's divide 43515 by 9
We're looking to find how many times 9 goes into 43515.

Advancing to step 1:
4 divided by 9 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 9

Going ahead to step 2:
43 divided by 9 is 4 with a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 36 from 43 leaves us with 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 9

Advancing to step 3:
When dividing 75 by 9, we get 8 with a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 48.0
Deduct 72 from 75 and we're left with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 9

On to step 4:
If we divide 31 by 9, we get 3 and a remainder of 4.
The next digit of our result is 3. 
Result so far: 483.0
If we subtract 27 from 31, we get 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 9

Moving on to step 5:
If we divide 45 by 9, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 4835.0
If we take 45 away from 45, 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 6:
If we divide 0 by 9, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 4835.0
Subtracting 0 from 0 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.

Step 7:
The number 9 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4835.0
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.

The final outcome is 4835.0, with a leftover of 0.0.
