24540210 ÷ 15 
We want to figure out the number of times 24540210 can be divided by 15.

Step 1:
If we divide 2 by 15, we get 0 and 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 (4) from the dividend after 2, then repeat: 24 / 15

Advancing to step 2:
24 divided by 15 is 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 9 after subtracting 15 from 24.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 15

Let's proceed to step 3:
15 goes into 95 6 times with a remainder of 5.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Deduct 90 from 95 and we're left with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 15

Going ahead to step 4:
When dividing 54 by 15, we get 3 with a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 163.0
The remainder is 9 after subtracting 45 from 54.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 15

Step 5:
15 goes into 90 6 times with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 1636.0
Subtract 90 from 90 to get 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 15

On to step 6:
If we divide 2 by 15, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 16360.0
If we take 0 away from 2, we end up with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 15

Going ahead to step 7:
If we divide 21 by 15, we get 1 and a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 163601.0
Subtracting 15 from 21 leaves us with 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 15

Going ahead to step 8:
The number 15 fits into 60 4 times, leaving a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 1636014.0
If we subtract 60 from 60, 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:
When dividing 0 by 15, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 1636014.0
Subtract 0 from 0 to 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 10:
The number 15 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1636014.0
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.

The quotient of the division is 1636014.0, and the remainder is 0.0.
