We divide 23815 by 15
Let's see how many times 15 fits into 23815.

On to step 1:
When dividing 2 by 15, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 15

Moving on to step 2:
15 goes into 23 1 times with 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.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 15

Moving on to step 3:
The number 15 fits into 88 5 times, leaving a remainder of 13.
Use 5 as the next digit of our solution. 
Result so far: 15.0
The remainder is 13 after subtracting 75 from 88.
Fetch the next digit (1) from the dividend, attach it to 13 and continue: 131 / 15

Step 4:
15 can be fit into 131 8 times, resulting in a remainder of 11.
Record the quotient 8 as the next digit in the result. 
Result so far: 158.0
Subtract 120 from 131 to get 11.
Append the next digit (5) from the dividend to 11 and continue with: 115 / 15

Let's proceed to step 5:
The number 15 fits into 115 7 times, leaving a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 1587.0
Subtract 105 from 115 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 6:
100 divided by 15 is 6 with a remainder of 10.
The next digit of our result is 6. 
Result so far: 1587.6
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
100 divided by 15 is 6 with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 1587.66
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 1587.66, and the remainder is 0.01.
