We look at the division of 778492 by 5 
The aim is to understand the frequency of 5 in 778492.

Advancing to step 1:
The number 5 fits into 7 1 times, leaving a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 2 after subtracting 5 from 7.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 5

Let's proceed to step 2:
5 can be fit into 27 5 times, resulting in a remainder of 2.
The next digit of our result is 5. 
Result so far: 15.0
Subtracting 25 from 27 leaves us with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 5

Advancing to step 3:
The number 5 fits into 28 5 times, leaving a remainder of 3.
The next digit of our result is 5. 
Result so far: 155.0
If we subtract 25 from 28, we get 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 5

On to step 4:
The number 5 fits into 34 6 times, leaving a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 1556.0
If we take 30 away from 34, we end up with 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 5

Step 5:
5 can be fit into 49 9 times, resulting in a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 15569.0
The remainder is 4 after subtracting 45 from 49.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 5

On to step 6:
If we divide 42 by 5, we get 8 and a remainder of 2.
The next digit of our result is 8. 
Result so far: 155698.0
If we take 40 away from 42, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
The number 5 fits into 20 4 times, leaving a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 155698.4
The remainder is 0 after subtracting 20 from 20.
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.
Put 0 as the next digit of the answer. 
Result so far: 155698.4
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.

Step 9:
When dividing 0 by 5, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 155698.4
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 155698.4, with a leftover of 0.0.
