Let's divide 50500 by 18
The aim is to understand the frequency of 18 in 50500.

Step 1:
When dividing 5 by 18, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 18

Let's proceed to step 2:
The number 18 fits into 50 2 times, leaving a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 14 after subtracting 36 from 50.
Bring next digit (5) of the dividend behind the 14 and repeat the process: 145 / 18

Let's proceed to step 3:
The number 18 fits into 145 8 times, leaving a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 28.0
Subtracting 144 from 145 leaves us with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 18

Step 4:
18 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 280.0
The remainder is 10 after subtracting 0 from 10.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 18

Step 5:
If we divide 100 by 18, we get 5 and a remainder of 10.
The next digit of our result is 5. 
Result so far: 2805.0
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 6:
100 divided by 18 is 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 2805.5
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
18 can be fit into 100 5 times, resulting in a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 2805.55
If we subtract 90 from 100, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 2805.55 with a balance of 0.01.
