We look at the division of 948805 by 20 
The aim is to understand the frequency of 20 in 948805.

Advancing to step 1:
If we divide 9 by 20, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (4) from the dividend, attach it to 9 and continue: 94 / 20

Going ahead to step 2:
The number 20 fits into 94 4 times, leaving a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 80 from 94, we get 14.
Fetch the next digit (8) from the dividend, attach it to 14 and continue: 148 / 20

Moving on to step 3:
148 divided by 20 is 7 with a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
If we take 140 away from 148, we end up with 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 20

Moving on to step 4:
20 can be fit into 88 4 times, resulting in a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 474.0
If we subtract 80 from 88, we get 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 20

Moving on to step 5:
20 can be fit into 80 4 times, resulting in a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 4744.0
Subtracting 80 from 80 leaves us with 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 20

Moving on to step 6:
20 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 47440.0
Deduct 0 from 5 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
20 can be fit into 50 2 times, resulting in a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 47440.2
Deduct 40 from 50 and we're left 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 8:
20 can be fit into 100 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 47440.25
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:
20 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 47440.25
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.

Going ahead to step 10:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 47440.25
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.

The quotient of the division is 47440.25, and the remainder is 0.0.
