We look at the division of 284761 by 20 
The aim is to understand the frequency of 20 in 284761.

Moving on to step 1:
2 divided by 20 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 20

On to step 2:
28 divided by 20 is 1 with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 20 from 28 to get 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 20

Let's proceed to step 3:
20 can be fit into 84 4 times, resulting in a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtracting 80 from 84 leaves us with 4.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 20

On to step 4:
The number 20 fits into 47 2 times, leaving a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 142.0
If we take 40 away from 47, we end up with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 20

Moving on to step 5:
20 can be fit into 76 3 times, resulting in a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 1423.0
Subtract 60 from 76 to get 16.
Append the next digit (1) from the dividend to 16 and continue with: 161 / 20

Going ahead to step 6:
20 goes into 161 8 times with a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 14238.0
Subtract 160 from 161 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
The number 20 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 14238.0
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:
100 divided by 20 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 14238.05
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.

Let's proceed to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 14238.05
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.
The next digit of our result is 0. 
Result so far: 14238.05
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.

After the division, we end up with 14238.05 and a remainder of 0.0.
