380339 ÷ 20 
The aim is to understand the frequency of 20 in 380339.

Moving on to step 1:
20 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 20

Let's proceed to step 2:
When dividing 38 by 20, we get 1 with a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 20 away from 38, we end up with 18.
Bring next digit (0) of the dividend behind the 18 and repeat the process: 180 / 20

On to step 3:
The number 20 fits into 180 9 times, leaving a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 19.0
If we take 180 away from 180, we end up with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 20

Advancing to step 4:
When dividing 3 by 20, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 190.0
If we take 0 away from 3, we end up with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 20

Going ahead to step 5:
If we divide 33 by 20, we get 1 and a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 1901.0
The remainder is 13 after subtracting 20 from 33.
Grab the next digit (9) from the dividend, add it to 13, then carry on: 139 / 20

Moving on to step 6:
139 divided by 20 is 6 with a remainder of 19.
The number 6 becomes the next digit in our result. 
Result so far: 19016.0
If we take 120 away from 139, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 7:
190 divided by 20 is 9 with a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 19016.9
The remainder is 10 after subtracting 180 from 190.
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:
The number 20 fits into 100 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 19016.95
If we subtract 100 from 100, 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.

Let's proceed to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 19016.95
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.

Let's proceed to step 10:
0 divided by 20 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 19016.95
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 19016.95 and a remainder of 0.0.
