386480 divided by 20 
The aim is to understand the frequency of 20 in 386480.

Moving on to step 1:
3 divided by 20 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 20

Let's proceed to step 2:
The number 20 fits into 38 1 times, leaving a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 20 from 38 and we're left with 18.
Take the next digit (6) from the dividend and append it to 18, then repeat: 186 / 20

Moving on to step 3:
If we divide 186 by 20, we get 9 and a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 19.0
If we subtract 180 from 186, we get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 20

Advancing to step 4:
If we divide 64 by 20, we get 3 and a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 193.0
Subtract 60 from 64 to get 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 20

Let's proceed to step 5:
20 goes into 48 2 times with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 1932.0
The remainder is 8 after subtracting 40 from 48.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 20

Advancing to step 6:
20 can be fit into 80 4 times, resulting in a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 19324.0
Subtract 80 from 80 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 7:
0 divided by 20 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 19324.0
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.

Moving on to step 8:
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: 19324.0
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.

The final outcome is 19324.0, with a leftover of 0.0.
