298978 ÷ 20 
The aim is to understand the frequency of 20 in 298978.

Advancing to step 1:
2 divided by 20 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 20

Let's proceed to step 2:
If we divide 29 by 20, we get 1 and a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 20 from 29 and we're left with 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 20

Let's proceed to step 3:
If we divide 98 by 20, we get 4 and a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 14.0
The remainder is 18 after subtracting 80 from 98.
Append the next digit (9) from the dividend to 18 and continue with: 189 / 20

Going ahead to step 4:
When dividing 189 by 20, we get 9 with a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 149.0
Deduct 180 from 189 and we're left with 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 20

Moving on to step 5:
97 divided by 20 is 4 with a remainder of 17.
Write down 4 as next digit of the result. 
Result so far: 1494.0
The remainder is 17 after subtracting 80 from 97.
Bring next digit (8) of the dividend behind the 17 and repeat the process: 178 / 20

Going ahead to step 6:
20 can be fit into 178 8 times, resulting in a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 14948.0
Subtracting 160 from 178 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
20 goes into 180 9 times with a remainder of 0.
The next digit of our result is 9. 
Result so far: 14948.9
The remainder is 0 after subtracting 180 from 180.
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 8:
20 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 14948.9
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.

Step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 14948.9
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.

After the division, we end up with 14948.9 and a remainder of 0.0.
