We look at the division of 15087909 by 240 
We're looking to find how many times 240 goes into 15087909.

Moving on to step 1:
240 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 240

Let's proceed to step 2:
15 divided by 240 is 0 with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Include the next digit (0) from the dividend after 15, then repeat: 150 / 240

On to step 3:
When dividing 150 by 240, we get 0 with a remainder of 150.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 150, we get 150.
Grab the next digit (8) from the dividend, add it to 150, then carry on: 1508 / 240

Going ahead to step 4:
The number 240 fits into 1508 6 times, leaving a remainder of 68.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 1440 away from 1508, we end up with 68.
Append the next digit (7) from the dividend to 68 and continue with: 687 / 240

Step 5:
When dividing 687 by 240, we get 2 with a remainder of 207.
Put 2 as the next digit of the answer. 
Result so far: 62.0
The remainder is 207 after subtracting 480 from 687.
Bring next digit (9) of the dividend behind the 207 and repeat the process: 2079 / 240

Going ahead to step 6:
When dividing 2079 by 240, we get 8 with a remainder of 159.
The number 8 becomes the next digit in our result. 
Result so far: 628.0
Deduct 1920 from 2079 and we're left with 159.
Grab the next digit (0) from the dividend, add it to 159, then carry on: 1590 / 240

Step 7:
When dividing 1590 by 240, we get 6 with a remainder of 150.
The next digit of our result is 6. 
Result so far: 6286.0
Subtract 1440 from 1590 to get 150.
Take the next digit (9) from the dividend and append it to 150, then repeat: 1509 / 240

Advancing to step 8:
The number 240 fits into 1509 6 times, leaving a remainder of 69.
Write down 6 as next digit of the result. 
Result so far: 62866.0
If we take 1440 away from 1509, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 9:
690 divided by 240 is 2 with a remainder of 210.
Put 2 as the next digit of the answer. 
Result so far: 62866.2
Subtracting 480 from 690 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

On to step 10:
2100 divided by 240 is 8 with a remainder of 180.
The next digit of our result is 8. 
Result so far: 62866.28
The remainder is 180 after subtracting 1920 from 2100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 11:
1800 divided by 240 is 7 with a remainder of 120.
The next digit of our result is 7. 
Result so far: 62866.287
If we subtract 1680 from 1800, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 12:
If we divide 1200 by 240, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 62866.2875
If we take 1200 away from 1200, 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.

Step 13:
When dividing 0 by 240, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 62866.2875
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.

Step 14:
When dividing 0 by 240, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 62866.2875
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 62866.2875, and the remainder is 0.0.
