We look at the division of 124719 by 5 
The aim is to understand the frequency of 5 in 124719.

Going ahead to step 1:
1 divided by 5 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 5

Moving on to step 2:
If we divide 12 by 5, we get 2 and a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 10 from 12, we get 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 5

On to step 3:
5 can be fit into 24 4 times, resulting in a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
Deduct 20 from 24 and we're left with 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 5

Step 4:
5 can be fit into 47 9 times, resulting in a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 249.0
If we take 45 away from 47, we end up with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 5

Advancing to step 5:
5 goes into 21 4 times with a remainder of 1.
The next digit of our result is 4. 
Result so far: 2494.0
If we subtract 20 from 21, we get 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 5

Advancing to step 6:
The number 5 fits into 19 3 times, leaving a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 24943.0
If we subtract 15 from 19, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
5 goes into 40 8 times with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 24943.8
Subtract 40 from 40 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.

Advancing to step 8:
When dividing 0 by 5, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 24943.8
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.

Step 9:
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: 24943.8
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.

The final result is 24943.8 with a remainder of 0.0.
