19113 ÷ 20 
The aim is to understand the frequency of 20 in 19113.

Step 1:
The number 20 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 20

On to step 2:
20 can be fit into 19 0 times, resulting in a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 19, we get 19.
Append the next digit (1) from the dividend to 19 and continue with: 191 / 20

Let's proceed to step 3:
If we divide 191 by 20, we get 9 and a remainder of 11.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 180 from 191 and we're left with 11.
Append the next digit (1) from the dividend to 11 and continue with: 111 / 20

Step 4:
20 goes into 111 5 times with a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 95.0
If we subtract 100 from 111, we get 11.
Include the next digit (3) from the dividend after 11, then repeat: 113 / 20

On to step 5:
20 can be fit into 113 5 times, resulting in a remainder of 13.
Put 5 as the next digit of the answer. 
Result so far: 955.0
The remainder is 13 after subtracting 100 from 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 6:
The number 20 fits into 130 6 times, leaving a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 955.6
Deduct 120 from 130 and we're left with 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.
Use 5 as the next digit of our solution. 
Result so far: 955.65
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.

Moving on to step 8:
If we divide 0 by 20, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 955.65
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.

Moving on 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: 955.65
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.

Our division results in 955.65 with a remaining 0.0.
