We're dividing 31155066 by 687 
We're looking to find how many times 687 goes into 31155066.

Advancing to step 1:
If we divide 3 by 687, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 687

Step 2:
687 can be fit into 31 0 times, resulting in a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Include the next digit (1) from the dividend after 31, then repeat: 311 / 687

Let's proceed to step 3:
687 goes into 311 0 times with a remainder of 311.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 311, we get 311.
Append the next digit (5) from the dividend to 311 and continue with: 3115 / 687

Let's proceed to step 4:
687 goes into 3115 4 times with a remainder of 367.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 2748 from 3115, we get 367.
Bring next digit (5) of the dividend behind the 367 and repeat the process: 3675 / 687

On to step 5:
3675 divided by 687 is 5 with a remainder of 240.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
Deduct 3435 from 3675 and we're left with 240.
Append the next digit (0) from the dividend to 240 and continue with: 2400 / 687

Advancing to step 6:
687 goes into 2400 3 times with a remainder of 339.
Use 3 as the next digit of our solution. 
Result so far: 453.0
If we subtract 2061 from 2400, we get 339.
Fetch the next digit (6) from the dividend, attach it to 339 and continue: 3396 / 687

Step 7:
3396 divided by 687 is 4 with a remainder of 648.
Write down 4 as next digit of the result. 
Result so far: 4534.0
The remainder is 648 after subtracting 2748 from 3396.
Bring next digit (6) of the dividend behind the 648 and repeat the process: 6486 / 687

Let's proceed to step 8:
The number 687 fits into 6486 9 times, leaving a remainder of 303.
Put 9 as the next digit of the answer. 
Result so far: 45349.0
If we subtract 6183 from 6486, we get 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

Going ahead to step 9:
If we divide 3030 by 687, we get 4 and a remainder of 282.
Use 4 as the next digit of our solution. 
Result so far: 45349.4
Deduct 2748 from 3030 and we're left with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

On to step 10:
When dividing 2820 by 687, we get 4 with a remainder of 72.
Record the quotient 4 as the next digit in the result. 
Result so far: 45349.44
Subtract 2748 from 2820 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

In conclusion, the division gives 45349.44 with a balance of 0.072.
