We look at the division of 303009 by 5 
The aim is to understand the frequency of 5 in 303009.

Going ahead to step 1:
3 divided by 5 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 5

On to step 2:
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: 6.0
Subtract 30 from 30 to get 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 5

On to step 3:
When dividing 3 by 5, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 60.0
If we subtract 0 from 3, we get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 5

Going ahead to step 4:
5 goes into 30 6 times with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 606.0
Subtract 30 from 30 to get 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 5

Step 5:
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: 6060.0
The remainder is 0 after subtracting 0 from 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 5

Let's proceed to step 6:
5 goes into 9 1 times with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 60601.0
Subtracting 5 from 9 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
If we divide 40 by 5, we get 8 and a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 60601.8
If we subtract 40 from 40, 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.

Advancing to step 8:
The number 5 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 60601.8
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.

Advancing to step 9:
The number 5 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 60601.8
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.

In conclusion, the division gives 60601.8 with a balance of 0.0.
