We look at the division of 814543 by 5 
The aim is to understand the frequency of 5 in 814543.

Going ahead to step 1:
If we divide 8 by 5, we get 1 and a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 5 away from 8, we end up with 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 5

Advancing to step 2:
When dividing 31 by 5, we get 6 with a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 16.0
If we take 30 away from 31, we end up with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 5

Going ahead to step 3:
When dividing 14 by 5, we get 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 162.0
The remainder is 4 after subtracting 10 from 14.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 5

Moving on to step 4:
When dividing 45 by 5, we get 9 with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 1629.0
If we subtract 45 from 45, we get 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 5

Step 5:
5 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 16290.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 5

Going ahead to step 6:
When dividing 43 by 5, we get 8 with a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 162908.0
Subtracting 40 from 43 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.

Advancing to step 7:
When dividing 30 by 5, we get 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 162908.6
If we subtract 30 from 30, 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.

On to step 8:
5 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 162908.6
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.

On to step 9:
5 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 162908.6
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 162908.6, with a leftover of 0.0.
