We're dividing 862841 by 20 
The aim is to understand the frequency of 20 in 862841.

Let's proceed to step 1:
The number 20 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 20

Moving on to step 2:
86 divided by 20 is 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 80 from 86 to get 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 20

On to step 3:
The number 20 fits into 62 3 times, leaving a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
Subtracting 60 from 62 leaves us with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 20

Step 4:
28 divided by 20 is 1 with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 431.0
If we subtract 20 from 28, we get 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 20

Let's proceed to step 5:
If we divide 84 by 20, we get 4 and a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 4314.0
Deduct 80 from 84 and we're left with 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 20

Let's proceed to step 6:
20 goes into 41 2 times with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 43142.0
If we take 40 away from 41, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
20 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 43142.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
If we divide 100 by 20, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 43142.05
The remainder is 0 after subtracting 100 from 100.
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 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 43142.05
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.
Write down 0 as next digit of the result. 
Result so far: 43142.05
If we take 0 away from 0, 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.

Our division results in 43142.05 with a remaining 0.0.
