373496 divided by 20 
The aim is to understand the frequency of 20 in 373496.

Advancing to step 1:
When dividing 3 by 20, we get 0 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.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 20

Let's proceed to step 2:
37 divided by 20 is 1 with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 20 away from 37, we end up with 17.
Include the next digit (3) from the dividend after 17, then repeat: 173 / 20

Step 3:
If we divide 173 by 20, we get 8 and a remainder of 13.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
If we take 160 away from 173, we end up with 13.
Bring next digit (4) of the dividend behind the 13 and repeat the process: 134 / 20

Going ahead to step 4:
134 divided by 20 is 6 with a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 186.0
The remainder is 14 after subtracting 120 from 134.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 20

On to step 5:
20 can be fit into 149 7 times, resulting in a remainder of 9.
The next digit of our result is 7. 
Result so far: 1867.0
If we take 140 away from 149, we end up with 9.
Take the next digit (6) from the dividend and append it to 9, then repeat: 96 / 20

Step 6:
96 divided by 20 is 4 with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 18674.0
Subtract 80 from 96 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 7:
20 goes into 160 8 times with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 18674.8
The remainder is 0 after subtracting 160 from 160.
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.
Use 0 as the next digit of our solution. 
Result so far: 18674.8
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.

On to step 9:
20 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 18674.8
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 outcome is 18674.8, with a leftover of 0.0.
