We're dividing 23835 by 15 
We want to figure out the number of times 23835 can be divided by 15.

On to step 1:
When dividing 2 by 15, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 15

Going ahead to step 2:
15 can be fit into 23 1 times, resulting in a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 15 from 23 to get 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 15

Let's proceed to step 3:
88 divided by 15 is 5 with a remainder of 13.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtracting 75 from 88 leaves us with 13.
Append the next digit (3) from the dividend to 13 and continue with: 133 / 15

Step 4:
15 can be fit into 133 8 times, resulting in a remainder of 13.
The next digit of our result is 8. 
Result so far: 158.0
The remainder is 13 after subtracting 120 from 133.
Append the next digit (5) from the dividend to 13 and continue with: 135 / 15

Moving on to step 5:
15 can be fit into 135 9 times, resulting in a remainder of 0.
The next digit of our result is 9. 
Result so far: 1589.0
Subtracting 135 from 135 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.

Advancing to step 6:
0 divided by 15 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1589.0
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 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: 1589.0
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.

The final outcome is 1589.0, with a leftover of 0.0.
