Let's divide 820741 by 20
The aim is to understand the frequency of 20 in 820741.

Step 1:
If we divide 8 by 20, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 20

Let's proceed to step 2:
When dividing 82 by 20, we get 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 80 from 82 and we're left with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 20

Step 3:
The number 20 fits into 20 1 times, leaving a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
If we take 20 away from 20, we end up with 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 20

Let's proceed to step 4:
20 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 410.0
Subtract 0 from 7 to get 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 20

Going ahead to step 5:
74 divided by 20 is 3 with a remainder of 14.
The number 3 becomes the next digit in our result. 
Result so far: 4103.0
If we take 60 away from 74, we end up with 14.
Take the next digit (1) from the dividend and append it to 14, then repeat: 141 / 20

Step 6:
If we divide 141 by 20, we get 7 and a remainder of 1.
The next digit of our result is 7. 
Result so far: 41037.0
The remainder is 1 after subtracting 140 from 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
20 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 41037.0
Subtract 0 from 10 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.

Going ahead to step 8:
The number 20 fits into 100 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 41037.05
Subtract 100 from 100 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:
20 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 41037.05
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.

Advancing to step 10:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 41037.05
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.

The quotient of the division is 41037.05, and the remainder is 0.0.
