383040 ÷ 20 
The aim is to understand the frequency of 20 in 383040.

Step 1:
20 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 20

Step 2:
When dividing 38 by 20, we get 1 with a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 20 from 38 leaves us with 18.
Include the next digit (3) from the dividend after 18, then repeat: 183 / 20

Advancing to step 3:
20 can be fit into 183 9 times, resulting in a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 19.0
The remainder is 3 after subtracting 180 from 183.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 20

Moving on to step 4:
30 divided by 20 is 1 with a remainder of 10.
The next digit of our result is 1. 
Result so far: 191.0
The remainder is 10 after subtracting 20 from 30.
Include the next digit (4) from the dividend after 10, then repeat: 104 / 20

On to step 5:
104 divided by 20 is 5 with a remainder of 4.
The next digit of our result is 5. 
Result so far: 1915.0
If we take 100 away from 104, we end up with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 20

Going ahead to step 6:
40 divided by 20 is 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 19152.0
The remainder is 0 after subtracting 40 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
0 divided by 20 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 19152.0
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.

On to step 8:
20 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 19152.0
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.

After the division, we end up with 19152.0 and a remainder of 0.0.
