Let's divide 1221 by 5
The aim is to understand the frequency of 5 in 1221.

Let's proceed to step 1:
When dividing 1 by 5, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in 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

Step 2:
12 divided by 5 is 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 10 from 12 leaves us with 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 5

Going ahead to step 3:
22 divided by 5 is 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 24.0
Deduct 20 from 22 and we're left with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 5

Let's proceed to step 4:
5 can be fit into 21 4 times, resulting in a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 244.0
If we subtract 20 from 21, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 5:
10 divided by 5 is 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 244.2
The remainder is 0 after subtracting 10 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 6:
If we divide 0 by 5, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 244.2
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.

Let's proceed to step 7:
The number 5 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 244.2
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 244.2 with a balance of 0.0.
