Let's divide 309012 by 5
The aim is to understand the frequency of 5 in 309012.

Advancing to step 1:
5 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 5

Going ahead to step 2:
The number 5 fits into 30 6 times, leaving a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 30 from 30 and we're left with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 5

Going ahead to step 3:
The number 5 fits into 9 1 times, leaving a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 61.0
Subtracting 5 from 9 leaves us with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 5

Let's proceed to step 4:
When dividing 40 by 5, we get 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 618.0
Subtract 40 from 40 to get 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 5

Let's proceed to step 5:
5 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 6180.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 5

Going ahead to step 6:
When dividing 12 by 5, we get 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 61802.0
Deduct 10 from 12 and we're left 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.

On to step 7:
The number 5 fits into 20 4 times, leaving a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 61802.4
If we subtract 20 from 20, 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 8:
0 divided by 5 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 61802.4
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.

Going ahead to step 9:
The number 5 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 61802.4
Deduct 0 from 0 and we're left 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.

In conclusion, the division gives 61802.4 with a balance of 0.0.
