We look at the division of 575378 by 5 
The aim is to understand the frequency of 5 in 575378.

Advancing to step 1:
5 can be fit into 5 1 times, resulting in a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 5 away from 5, we end up with 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 5

Let's proceed to step 2:
The number 5 fits into 7 1 times, leaving a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we take 5 away from 7, we end up with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 5

Step 3:
5 goes into 25 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 115.0
Subtract 25 from 25 to get 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 5

Going ahead to step 4:
If we divide 3 by 5, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 1150.0
If we subtract 0 from 3, we get 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 5

On to step 5:
The number 5 fits into 37 7 times, leaving a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 11507.0
If we subtract 35 from 37, we get 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 5

Moving on to step 6:
The number 5 fits into 28 5 times, leaving a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 115075.0
The remainder is 3 after subtracting 25 from 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
If we divide 30 by 5, we get 6 and a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 115075.6
Subtracting 30 from 30 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.

Moving on to step 8:
If we divide 0 by 5, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 115075.6
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.

Going ahead to step 9:
5 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 115075.6
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.

The final result is 115075.6 with a remainder of 0.0.
