We look at the division of 689980 by 5 
The aim is to understand the frequency of 5 in 689980.

Let's proceed to step 1:
5 can be fit into 6 1 times, resulting in a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 5 from 6 and we're left with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 5

Step 2:
5 can be fit into 18 3 times, resulting in a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we take 15 away from 18, we end up with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 5

Going ahead to step 3:
When dividing 39 by 5, we get 7 with a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 137.0
Subtracting 35 from 39 leaves us with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 5

Advancing to step 4:
5 goes into 49 9 times with a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 1379.0
The remainder is 4 after subtracting 45 from 49.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 5

Advancing to step 5:
When dividing 48 by 5, we get 9 with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 13799.0
If we take 45 away from 48, we end up with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 5

Step 6:
30 divided by 5 is 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 137996.0
Deduct 30 from 30 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.

Going ahead to step 7:
5 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 137996.0
If we take 0 away from 0, 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.

Advancing to step 8:
If we divide 0 by 5, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 137996.0
If we take 0 away from 0, 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.

The final outcome is 137996.0, with a leftover of 0.0.
