Let's divide 371307 by 20
The aim is to understand the frequency of 20 in 371307.

On to step 1:
3 divided by 20 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 20

Advancing to step 2:
20 goes into 37 1 times with a remainder of 17.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 17 after subtracting 20 from 37.
Bring next digit (1) of the dividend behind the 17 and repeat the process: 171 / 20

On to step 3:
171 divided by 20 is 8 with a remainder of 11.
The next digit of our result is 8. 
Result so far: 18.0
The remainder is 11 after subtracting 160 from 171.
Grab the next digit (3) from the dividend, add it to 11, then carry on: 113 / 20

Step 4:
When dividing 113 by 20, we get 5 with a remainder of 13.
Record the quotient 5 as the next digit in the result. 
Result so far: 185.0
If we subtract 100 from 113, we get 13.
Append the next digit (0) from the dividend to 13 and continue with: 130 / 20

Going ahead to step 5:
20 can be fit into 130 6 times, resulting in a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 1856.0
Deduct 120 from 130 and we're left with 10.
Grab the next digit (7) from the dividend, add it to 10, then carry on: 107 / 20

Let's proceed to step 6:
20 goes into 107 5 times with a remainder of 7.
The next digit of our result is 5. 
Result so far: 18565.0
Subtracting 100 from 107 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
70 divided by 20 is 3 with a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 18565.3
Deduct 60 from 70 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.

Let's proceed to step 8:
The number 20 fits into 100 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 18565.35
Subtract 100 from 100 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.

Moving on to step 9:
0 divided by 20 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 18565.35
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.

Let's proceed to step 10:
If we divide 0 by 20, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 18565.35
Subtract 0 from 0 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.

The final result is 18565.35 with a remainder of 0.0.
