622770 divided by 20 
The aim is to understand the frequency of 20 in 622770.

Going ahead to step 1:
If we divide 6 by 20, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 20

Step 2:
62 divided by 20 is 3 with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 60 from 62 to get 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 20

Going ahead to step 3:
When dividing 22 by 20, we get 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 31.0
Deduct 20 from 22 and we're left with 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 20

Step 4:
20 can be fit into 27 1 times, resulting in a remainder of 7.
The next digit of our result is 1. 
Result so far: 311.0
If we subtract 20 from 27, we get 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 20

Moving on to step 5:
If we divide 77 by 20, we get 3 and a remainder of 17.
The next digit of our result is 3. 
Result so far: 3113.0
If we subtract 60 from 77, we get 17.
Grab the next digit (0) from the dividend, add it to 17, then carry on: 170 / 20

Moving on to step 6:
20 can be fit into 170 8 times, resulting in a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 31138.0
If we take 160 away from 170, 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.

Let's proceed to step 7:
When dividing 100 by 20, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 31138.5
If we subtract 100 from 100, 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.

Moving on to step 8:
20 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 31138.5
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.

Step 9:
20 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 31138.5
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.

After the division, we end up with 31138.5 and a remainder of 0.0.
