Let's divide 375419 by 20
The aim is to understand the frequency of 20 in 375419.

Going ahead to step 1:
The number 20 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 20

Step 2:
The number 20 fits into 37 1 times, leaving a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 20 from 37 and we're left with 17.
Include the next digit (5) from the dividend after 17, then repeat: 175 / 20

Moving on to step 3:
When dividing 175 by 20, we get 8 with a remainder of 15.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
The remainder is 15 after subtracting 160 from 175.
Fetch the next digit (4) from the dividend, attach it to 15 and continue: 154 / 20

Moving on to step 4:
154 divided by 20 is 7 with a remainder of 14.
The next digit of our result is 7. 
Result so far: 187.0
Subtract 140 from 154 to get 14.
Fetch the next digit (1) from the dividend, attach it to 14 and continue: 141 / 20

On to step 5:
The number 20 fits into 141 7 times, leaving a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 1877.0
If we subtract 140 from 141, we get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 20

Advancing to step 6:
When dividing 19 by 20, we get 0 with a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 18770.0
Deduct 0 from 19 and we're left 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: 18770.9
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.

Let's proceed to step 8:
When dividing 100 by 20, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 18770.95
Subtracting 100 from 100 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 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: 18770.95
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.

Step 10:
20 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 18770.95
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 18770.95 and a remainder of 0.0.
