688587 ÷ 5 
We're looking to find how many times 5 goes into 688587.

On to step 1:
When dividing 6 by 5, we get 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 1 after subtracting 5 from 6.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 5

On to step 2:
5 can be fit into 18 3 times, resulting in a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtracting 15 from 18 leaves us with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 5

Going ahead to step 3:
If we divide 38 by 5, we get 7 and a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 137.0
If we take 35 away from 38, we end up with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 5

Step 4:
35 divided by 5 is 7 with a remainder of 0.
The next digit of our result is 7. 
Result so far: 1377.0
Deduct 35 from 35 and we're left with 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 5

On to step 5:
The number 5 fits into 8 1 times, leaving a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 13771.0
Subtract 5 from 8 to get 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 5

Let's proceed to step 6:
5 goes into 37 7 times with a remainder of 2.
The next digit of our result is 7. 
Result so far: 137717.0
Subtracting 35 from 37 leaves us 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.

Going ahead to step 7:
The number 5 fits into 20 4 times, leaving a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 137717.4
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.

Moving on to step 8:
5 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 137717.4
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.

Step 9:
0 divided by 5 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 137717.4
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.

The final outcome is 137717.4, with a leftover of 0.0.
