Let's divide 978425 by 20
The aim is to understand the frequency of 20 in 978425.

Moving on to step 1:
When dividing 9 by 20, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 20

Going ahead to step 2:
The number 20 fits into 97 4 times, leaving a remainder of 17.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 17 after subtracting 80 from 97.
Grab the next digit (8) from the dividend, add it to 17, then carry on: 178 / 20

On to step 3:
The number 20 fits into 178 8 times, leaving a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 48.0
Subtracting 160 from 178 leaves us with 18.
Fetch the next digit (4) from the dividend, attach it to 18 and continue: 184 / 20

Let's proceed to step 4:
If we divide 184 by 20, we get 9 and a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 489.0
If we subtract 180 from 184, we get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 20

Advancing to step 5:
42 divided by 20 is 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 4892.0
If we subtract 40 from 42, we get 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 20

Step 6:
25 divided by 20 is 1 with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 48921.0
Deduct 20 from 25 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.

Let's proceed to step 7:
50 divided by 20 is 2 with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 48921.2
The remainder is 10 after subtracting 40 from 50.
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:
When dividing 100 by 20, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 48921.25
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 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: 48921.25
Subtracting 0 from 0 leaves us 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:
When dividing 0 by 20, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 48921.25
Subtracting 0 from 0 leaves us 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.

The final result is 48921.25 with a remainder of 0.0.
