149896 divided by 20 
The aim is to understand the frequency of 20 in 149896.

Advancing to step 1:
When dividing 1 by 20, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 20

Moving on to step 2:
The number 20 fits into 14 0 times, leaving a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 14 leaves us with 14.
Append the next digit (9) from the dividend to 14 and continue with: 149 / 20

Step 3:
When dividing 149 by 20, we get 7 with a remainder of 9.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 9 after subtracting 140 from 149.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 20

On to step 4:
98 divided by 20 is 4 with a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 74.0
Subtracting 80 from 98 leaves us with 18.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 20

Let's proceed to step 5:
20 goes into 189 9 times with a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 749.0
The remainder is 9 after subtracting 180 from 189.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 20

Advancing to step 6:
96 divided by 20 is 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 7494.0
If we take 80 away from 96, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 7:
The number 20 fits into 160 8 times, leaving a remainder of 0.
The next digit of our result is 8. 
Result so far: 7494.8
Subtract 160 from 160 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.

Let's proceed to step 8:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 7494.8
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 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: 7494.8
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.

The final result is 7494.8 with a remainder of 0.0.
