687040 divided by 5 
The aim is to understand the frequency of 5 in 687040.

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
If we subtract 5 from 6, we get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 5

Going ahead to step 2:
When dividing 18 by 5, we get 3 with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtracting 15 from 18 leaves us with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 5

Going ahead to step 3:
5 can be fit into 37 7 times, resulting in a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 137.0
If we subtract 35 from 37, we get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 5

Let's proceed to step 4:
5 goes into 20 4 times with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 1374.0
The remainder is 0 after subtracting 20 from 20.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 5

On to step 5:
The number 5 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 13740.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 5

Moving on to step 6:
40 divided by 5 is 8 with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 137408.0
If we take 40 away from 40, we end up 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.

Moving on to step 7:
0 divided by 5 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 137408.0
The remainder is 0 after subtracting 0 from 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 8:
When dividing 0 by 5, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 137408.0
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.

In conclusion, the division gives 137408.0 with a balance of 0.0.
