We look at the division of 681687 by 4 
We want to figure out the number of times 681687 can be divided by 4.

On to step 1:
6 divided by 4 is 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 4 away from 6, we end up with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 4

Moving on to step 2:
If we divide 28 by 4, we get 7 and a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Deduct 28 from 28 and we're left with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 4

Moving on to step 3:
If we divide 1 by 4, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 170.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 4

Step 4:
4 can be fit into 16 4 times, resulting in a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 1704.0
Deduct 16 from 16 and we're left with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 4

Going ahead to step 5:
8 divided by 4 is 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 17042.0
The remainder is 0 after subtracting 8 from 8.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 4

Let's proceed to step 6:
7 divided by 4 is 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 170421.0
Subtracting 4 from 7 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
4 goes into 30 7 times with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 170421.7
Deduct 28 from 30 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
4 can be fit into 20 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 170421.75
Subtract 20 from 20 to 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.

Going ahead to step 9:
When dividing 0 by 4, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 170421.75
If we subtract 0 from 0, 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.

Advancing to step 10:
0 divided by 4 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 170421.75
Subtract 0 from 0 to 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.

The final outcome is 170421.75, with a leftover of 0.0.
