381103 ÷ 20 
The aim is to understand the frequency of 20 in 381103.

Moving on to step 1:
20 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 20

Advancing to step 2:
20 can be fit into 38 1 times, resulting in a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 20 from 38, we get 18.
Bring next digit (1) of the dividend behind the 18 and repeat the process: 181 / 20

Advancing to step 3:
The number 20 fits into 181 9 times, leaving a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Subtracting 180 from 181 leaves us with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 20

Advancing to step 4:
When dividing 11 by 20, we get 0 with a remainder of 11.
The next digit of our result is 0. 
Result so far: 190.0
If we take 0 away from 11, we end up with 11.
Take the next digit (0) from the dividend and append it to 11, then repeat: 110 / 20

Advancing to step 5:
20 can be fit into 110 5 times, resulting in a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 1905.0
If we take 100 away from 110, we end up with 10.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 20

On to step 6:
20 goes into 103 5 times with a remainder of 3.
The next digit of our result is 5. 
Result so far: 19055.0
The remainder is 3 after subtracting 100 from 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
When dividing 30 by 20, we get 1 with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 19055.1
Deduct 20 from 30 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.

Moving on to step 8:
20 can be fit into 100 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 19055.15
The remainder is 0 after subtracting 100 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
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: 19055.15
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 10:
When dividing 0 by 20, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 19055.15
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 result is 19055.15 with a remainder of 0.0.
