Let's divide 503230 by 20
The aim is to understand the frequency of 20 in 503230.

Going ahead to step 1:
If we divide 5 by 20, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 20

Advancing to step 2:
If we divide 50 by 20, we get 2 and a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 10 after subtracting 40 from 50.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 20

Moving on to step 3:
20 can be fit into 103 5 times, resulting in a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 25.0
If we subtract 100 from 103, we get 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 20

Let's proceed to step 4:
20 can be fit into 32 1 times, resulting in a remainder of 12.
The next digit of our result is 1. 
Result so far: 251.0
If we subtract 20 from 32, we get 12.
Grab the next digit (3) from the dividend, add it to 12, then carry on: 123 / 20

On to step 5:
123 divided by 20 is 6 with a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 2516.0
Subtracting 120 from 123 leaves us with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 20

Going ahead to step 6:
The number 20 fits into 30 1 times, leaving a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 25161.0
Deduct 20 from 30 and we're left 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.

Let's proceed to step 7:
If we divide 100 by 20, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 25161.5
If we take 100 away from 100, we end up 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.

Moving on to step 8:
0 divided by 20 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 25161.5
Subtract 0 from 0 to 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 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 25161.5
Subtract 0 from 0 to 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 25161.5 with a balance of 0.0.
