We look at the division of 209533 by 5 
The aim is to understand the frequency of 5 in 209533.

On to step 1:
When dividing 2 by 5, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 5

Advancing to step 2:
5 can be fit into 20 4 times, resulting in a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 20 from 20, we get 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 5

Moving on to step 3:
If we divide 9 by 5, we get 1 and a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 41.0
If we subtract 5 from 9, we get 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 5

Step 4:
5 goes into 45 9 times with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 419.0
If we subtract 45 from 45, we get 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 5

Going ahead to step 5:
The number 5 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 4190.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 5

On to step 6:
5 goes into 33 6 times with a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 41906.0
If we take 30 away from 33, we end up 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.

On to step 7:
If we divide 30 by 5, we get 6 and a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 41906.6
The remainder is 0 after subtracting 30 from 30.
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: 41906.6
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.

Advancing to step 9:
5 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 41906.6
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 41906.6, with a leftover of 0.0.
