Let's divide 15287999 by 240
We want to divide 15287999 by 240.

Let's proceed to step 1:
1 divided by 240 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 240

Advancing to step 2:
If we divide 15 by 240, we get 0 and a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Grab the next digit (2) from the dividend, add it to 15, then carry on: 152 / 240

On to step 3:
240 can be fit into 152 0 times, resulting in a remainder of 152.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 152 to get 152.
Bring next digit (8) of the dividend behind the 152 and repeat the process: 1528 / 240

On to step 4:
When dividing 1528 by 240, we get 6 with a remainder of 88.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 1440 from 1528 and we're left with 88.
Grab the next digit (7) from the dividend, add it to 88, then carry on: 887 / 240

Let's proceed to step 5:
887 divided by 240 is 3 with a remainder of 167.
Use 3 as the next digit of our solution. 
Result so far: 63.0
Deduct 720 from 887 and we're left with 167.
Take the next digit (9) from the dividend and append it to 167, then repeat: 1679 / 240

Step 6:
240 can be fit into 1679 6 times, resulting in a remainder of 239.
The number 6 becomes the next digit in our result. 
Result so far: 636.0
If we subtract 1440 from 1679, we get 239.
Take the next digit (9) from the dividend and append it to 239, then repeat: 2399 / 240

Moving on to step 7:
240 can be fit into 2399 9 times, resulting in a remainder of 239.
Write down 9 as next digit of the result. 
Result so far: 6369.0
The remainder is 239 after subtracting 2160 from 2399.
Include the next digit (9) from the dividend after 239, then repeat: 2399 / 240

Going ahead to step 8:
2399 divided by 240 is 9 with a remainder of 239.
The number 9 becomes the next digit in our result. 
Result so far: 63699.0
If we subtract 2160 from 2399, we get 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Step 9:
When dividing 2390 by 240, we get 9 with a remainder of 230.
Use 9 as the next digit of our solution. 
Result so far: 63699.9
The remainder is 230 after subtracting 2160 from 2390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Moving on to step 10:
240 goes into 2300 9 times with a remainder of 140.
Write down 9 as next digit of the result. 
Result so far: 63699.99
The remainder is 140 after subtracting 2160 from 2300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Our division results in 63699.99 with a remaining 0.14.
