We look at the division of 10815082 by 687 
We want to figure out the number of times 10815082 can be divided by 687.

Advancing to step 1:
The number 687 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 687

Advancing to step 2:
The number 687 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 10 after subtracting 0 from 10.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 687

Advancing to step 3:
If we divide 108 by 687, we get 0 and a remainder of 108.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 108, we get 108.
Fetch the next digit (1) from the dividend, attach it to 108 and continue: 1081 / 687

Step 4:
When dividing 1081 by 687, we get 1 with a remainder of 394.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 687 from 1081 and we're left with 394.
Include the next digit (5) from the dividend after 394, then repeat: 3945 / 687

Advancing to step 5:
If we divide 3945 by 687, we get 5 and a remainder of 510.
The next digit of our result is 5. 
Result so far: 15.0
The remainder is 510 after subtracting 3435 from 3945.
Bring next digit (0) of the dividend behind the 510 and repeat the process: 5100 / 687

On to step 6:
The number 687 fits into 5100 7 times, leaving a remainder of 291.
Use 7 as the next digit of our solution. 
Result so far: 157.0
The remainder is 291 after subtracting 4809 from 5100.
Include the next digit (8) from the dividend after 291, then repeat: 2918 / 687

On to step 7:
687 can be fit into 2918 4 times, resulting in a remainder of 170.
Put 4 as the next digit of the answer. 
Result so far: 1574.0
Subtract 2748 from 2918 to get 170.
Bring next digit (2) of the dividend behind the 170 and repeat the process: 1702 / 687

On to step 8:
687 can be fit into 1702 2 times, resulting in a remainder of 328.
The next digit of our result is 2. 
Result so far: 15742.0
Subtracting 1374 from 1702 leaves us with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Advancing to step 9:
3280 divided by 687 is 4 with a remainder of 532.
The number 4 becomes the next digit in our result. 
Result so far: 15742.4
Subtracting 2748 from 3280 leaves us with 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Let's proceed to step 10:
687 goes into 5320 7 times with a remainder of 511.
The next digit of our result is 7. 
Result so far: 15742.47
If we take 4809 away from 5320, we end up with 511.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5110, and continue the process.

On to step 11:
When dividing 5110 by 687, we get 7 with a remainder of 301.
Record the quotient 7 as the next digit in the result. 
Result so far: 15742.477
If we take 4809 away from 5110, we end up with 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

The final result is 15742.477 with a remainder of 0.0301.
