170938 divided by 20 
The aim is to understand the frequency of 20 in 170938.

Let's proceed to step 1:
1 divided by 20 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 20

Going ahead to step 2:
When dividing 17 by 20, we get 0 with a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Bring next digit (0) of the dividend behind the 17 and repeat the process: 170 / 20

Moving on to step 3:
20 goes into 170 8 times with a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 160 from 170 leaves us with 10.
Grab the next digit (9) from the dividend, add it to 10, then carry on: 109 / 20

Moving on to step 4:
109 divided by 20 is 5 with a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 85.0
Deduct 100 from 109 and we're left with 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 20

Going ahead to step 5:
93 divided by 20 is 4 with a remainder of 13.
Write down 4 as next digit of the result. 
Result so far: 854.0
Deduct 80 from 93 and we're left with 13.
Bring next digit (8) of the dividend behind the 13 and repeat the process: 138 / 20

Step 6:
20 goes into 138 6 times with a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 8546.0
Deduct 120 from 138 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 7:
180 divided by 20 is 9 with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 8546.9
If we subtract 180 from 180, 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.

Advancing to step 8:
0 divided by 20 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 8546.9
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.

Going ahead 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: 8546.9
Subtracting 0 from 0 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.

In conclusion, the division gives 8546.9 with a balance of 0.0.
