We divide 7815 by 24
We want to figure out the number of times 7815 can be divided by 24.

Let's proceed to step 1:
When dividing 7 by 24, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 24

Let's proceed to step 2:
The number 24 fits into 78 3 times, leaving a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 72 from 78 to get 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 24

On to step 3:
24 can be fit into 61 2 times, resulting in a remainder of 13.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
Subtracting 48 from 61 leaves us with 13.
Fetch the next digit (5) from the dividend, attach it to 13 and continue: 135 / 24

Going ahead to step 4:
24 can be fit into 135 5 times, resulting in a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 325.0
If we subtract 120 from 135, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 5:
If we divide 150 by 24, we get 6 and a remainder of 6.
The next digit of our result is 6. 
Result so far: 325.6
If we subtract 144 from 150, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 6:
24 goes into 60 2 times with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 325.62
If we subtract 48 from 60, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 7:
120 divided by 24 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 325.625
The remainder is 0 after subtracting 120 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
24 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 325.625
If we subtract 0 from 0, 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.

Step 9:
The number 24 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 325.625
If we subtract 0 from 0, 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.

Our division results in 325.625 with a remaining 0.0.
