We're dividing 422582 by 20 
The aim is to understand the frequency of 20 in 422582.

Step 1:
20 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 20

Advancing to step 2:
The number 20 fits into 42 2 times, leaving a remainder of 2.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 2 after subtracting 40 from 42.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 20

Step 3:
When dividing 22 by 20, we get 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
If we subtract 20 from 22, we get 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 20

Going ahead to step 4:
25 divided by 20 is 1 with a remainder of 5.
The next digit of our result is 1. 
Result so far: 211.0
Deduct 20 from 25 and we're left with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 20

Going ahead to step 5:
20 goes into 58 2 times with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 2112.0
Subtracting 40 from 58 leaves us with 18.
Bring next digit (2) of the dividend behind the 18 and repeat the process: 182 / 20

Let's proceed to step 6:
20 can be fit into 182 9 times, resulting in a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 21129.0
If we take 180 away from 182, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
20 goes into 20 1 times with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 21129.1
Subtract 20 from 20 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.

On to step 8:
When dividing 0 by 20, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 21129.1
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 21129.1
Subtracting 0 from 0 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.

Our division results in 21129.1 with a remaining 0.0.
