We look at the division of 15575235 by 687 
We're looking to find how many times 687 goes into 15575235.

Step 1:
When dividing 1 by 687, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 687

Let's proceed to step 2:
687 goes into 15 0 times with a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Take the next digit (5) from the dividend and append it to 15, then repeat: 155 / 687

Step 3:
When dividing 155 by 687, we get 0 with a remainder of 155.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 155 after subtracting 0 from 155.
Take the next digit (7) from the dividend and append it to 155, then repeat: 1557 / 687

On to step 4:
687 can be fit into 1557 2 times, resulting in a remainder of 183.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 183 after subtracting 1374 from 1557.
Grab the next digit (5) from the dividend, add it to 183, then carry on: 1835 / 687

Going ahead to step 5:
The number 687 fits into 1835 2 times, leaving a remainder of 461.
Write down 2 as next digit of the result. 
Result so far: 22.0
If we subtract 1374 from 1835, we get 461.
Grab the next digit (2) from the dividend, add it to 461, then carry on: 4612 / 687

Advancing to step 6:
The number 687 fits into 4612 6 times, leaving a remainder of 490.
The number 6 becomes the next digit in our result. 
Result so far: 226.0
If we subtract 4122 from 4612, we get 490.
Fetch the next digit (3) from the dividend, attach it to 490 and continue: 4903 / 687

On to step 7:
687 goes into 4903 7 times with a remainder of 94.
Write down 7 as next digit of the result. 
Result so far: 2267.0
Subtracting 4809 from 4903 leaves us with 94.
Bring next digit (5) of the dividend behind the 94 and repeat the process: 945 / 687

Moving on to step 8:
945 divided by 687 is 1 with a remainder of 258.
Write down 1 as next digit of the result. 
Result so far: 22671.0
The remainder is 258 after subtracting 687 from 945.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Moving on to step 9:
2580 divided by 687 is 3 with a remainder of 519.
The number 3 becomes the next digit in our result. 
Result so far: 22671.3
The remainder is 519 after subtracting 2061 from 2580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5190, and continue the process.

Going ahead to step 10:
687 goes into 5190 7 times with a remainder of 381.
The number 7 becomes the next digit in our result. 
Result so far: 22671.37
Deduct 4809 from 5190 and we're left with 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Let's proceed to step 11:
When dividing 3810 by 687, we get 5 with a remainder of 375.
Use 5 as the next digit of our solution. 
Result so far: 22671.375
Deduct 3435 from 3810 and we're left with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Let's proceed to step 12:
3750 divided by 687 is 5 with a remainder of 315.
Use 5 as the next digit of our solution. 
Result so far: 22671.3755
If we subtract 3435 from 3750, we get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

The final result is 22671.3755 with a remainder of 0.00315.
