We look at the division of 12425213 by 5 
The aim is to understand the frequency of 5 in 12425213.

Moving on to step 1:
5 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 5

Moving on to step 2:
The number 5 fits into 12 2 times, leaving a remainder of 2.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 10 from 12, we get 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 5

Advancing to step 3:
24 divided by 5 is 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
Deduct 20 from 24 and we're left with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 5

Advancing to step 4:
42 divided by 5 is 8 with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 248.0
The remainder is 2 after subtracting 40 from 42.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 5

Let's proceed to step 5:
5 goes into 25 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 2485.0
The remainder is 0 after subtracting 25 from 25.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 5

Moving on to step 6:
The number 5 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 24850.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 5

Going ahead to step 7:
When dividing 21 by 5, we get 4 with a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 248504.0
If we take 20 away from 21, we end up with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 5

On to step 8:
The number 5 fits into 13 2 times, leaving a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 2485042.0
If we subtract 10 from 13, we get 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 9:
5 goes into 30 6 times with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 2485042.6
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.

Advancing to step 10:
0 divided by 5 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 2485042.6
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 11:
5 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2485042.6
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 2485042.6 with a remainder of 0.0.
