We're dividing 73686251 by 687 
We want to figure out the number of times 73686251 can be divided by 687.

On to step 1:
687 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 687

Going ahead to step 2:
The number 687 fits into 73 0 times, leaving a remainder of 73.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 73 leaves us with 73.
Append the next digit (6) from the dividend to 73 and continue with: 736 / 687

Going ahead to step 3:
687 goes into 736 1 times with a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 49 after subtracting 687 from 736.
Bring next digit (8) of the dividend behind the 49 and repeat the process: 498 / 687

Going ahead to step 4:
687 goes into 498 0 times with a remainder of 498.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 498 and we're left with 498.
Append the next digit (6) from the dividend to 498 and continue with: 4986 / 687

Moving on to step 5:
The number 687 fits into 4986 7 times, leaving a remainder of 177.
Record the quotient 7 as the next digit in the result. 
Result so far: 107.0
Subtracting 4809 from 4986 leaves us with 177.
Fetch the next digit (2) from the dividend, attach it to 177 and continue: 1772 / 687

Let's proceed to step 6:
When dividing 1772 by 687, we get 2 with a remainder of 398.
Use 2 as the next digit of our solution. 
Result so far: 1072.0
If we subtract 1374 from 1772, we get 398.
Fetch the next digit (5) from the dividend, attach it to 398 and continue: 3985 / 687

Step 7:
687 can be fit into 3985 5 times, resulting in a remainder of 550.
The next digit of our result is 5. 
Result so far: 10725.0
Deduct 3435 from 3985 and we're left with 550.
Include the next digit (1) from the dividend after 550, then repeat: 5501 / 687

Let's proceed to step 8:
687 can be fit into 5501 8 times, resulting in a remainder of 5.
Write down 8 as next digit of the result. 
Result so far: 107258.0
Deduct 5496 from 5501 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
687 goes into 50 0 times with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 107258.0
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 10:
687 goes into 500 0 times with a remainder of 500.
Write down 0 as next digit of the result. 
Result so far: 107258.0
Subtracting 0 from 500 leaves us with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

In conclusion, the division gives 107258.0 with a balance of 0.5.
