50259 divided by 20 
The aim is to understand the frequency of 20 in 50259.

Step 1:
20 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 20

Moving on to step 2:
20 goes into 50 2 times with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 40 from 50 and we're left with 10.
Include the next digit (2) from the dividend after 10, then repeat: 102 / 20

Going ahead to step 3:
20 can be fit into 102 5 times, resulting in a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Subtracting 100 from 102 leaves us with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 20

Step 4:
25 divided by 20 is 1 with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 251.0
If we subtract 20 from 25, we get 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 20

Going ahead to step 5:
59 divided by 20 is 2 with a remainder of 19.
Use 2 as the next digit of our solution. 
Result so far: 2512.0
Subtracting 40 from 59 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 6:
If we divide 190 by 20, we get 9 and a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 2512.9
If we subtract 180 from 190, 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.

On to step 7:
The number 20 fits into 100 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 2512.95
Subtracting 100 from 100 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 8:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2512.95
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.

Moving on to step 9:
0 divided by 20 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 2512.95
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.

Our division results in 2512.95 with a remaining 0.0.
