584190 divided by 20 
The aim is to understand the frequency of 20 in 584190.

Let's proceed to step 1:
20 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 20

Advancing to step 2:
20 can be fit into 58 2 times, resulting in a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 40 from 58 to get 18.
Take the next digit (4) from the dividend and append it to 18, then repeat: 184 / 20

On to step 3:
When dividing 184 by 20, we get 9 with a remainder of 4.
The next digit of our result is 9. 
Result so far: 29.0
Subtract 180 from 184 to get 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 20

Let's proceed to step 4:
If we divide 41 by 20, we get 2 and a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 292.0
Deduct 40 from 41 and we're left with 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 20

Going ahead to step 5:
20 can be fit into 19 0 times, resulting in a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 2920.0
Subtracting 0 from 19 leaves us with 19.
Fetch the next digit (0) from the dividend, attach it to 19 and continue: 190 / 20

Moving on to step 6:
If we divide 190 by 20, we get 9 and a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 29209.0
Subtract 180 from 190 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
20 goes into 100 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 29209.5
Deduct 100 from 100 and we're left 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.

Advancing to step 8:
0 divided by 20 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 29209.5
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.

Advancing to step 9:
20 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 29209.5
Deduct 0 from 0 and we're left 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 result is 29209.5 with a remainder of 0.0.
