We look at the division of 687818 by 4 
We want to divide 687818 by 4.

Step 1:
4 can be fit into 6 1 times, resulting in a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 4 from 6 leaves us with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 4

On to step 2:
The number 4 fits into 28 7 times, leaving a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we subtract 28 from 28, we get 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 4

Moving on to step 3:
The number 4 fits into 7 1 times, leaving a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 171.0
The remainder is 3 after subtracting 4 from 7.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 4

Going ahead to step 4:
The number 4 fits into 38 9 times, leaving a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 1719.0
Subtracting 36 from 38 leaves us with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 4

Step 5:
21 divided by 4 is 5 with a remainder of 1.
The next digit of our result is 5. 
Result so far: 17195.0
Subtract 20 from 21 to get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 4

Moving on to step 6:
If we divide 18 by 4, we get 4 and a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 171954.0
If we subtract 16 from 18, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
The number 4 fits into 20 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 171954.5
If we subtract 20 from 20, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
The number 4 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 171954.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
If we divide 0 by 4, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 171954.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 171954.5 with a balance of 0.0.
