We divide 971423 by 20
The aim is to understand the frequency of 20 in 971423.

Going ahead to step 1:
20 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 20

Step 2:
20 can be fit into 97 4 times, resulting in a remainder of 17.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 17 after subtracting 80 from 97.
Bring next digit (1) of the dividend behind the 17 and repeat the process: 171 / 20

Moving on to step 3:
The number 20 fits into 171 8 times, leaving a remainder of 11.
The next digit of our result is 8. 
Result so far: 48.0
The remainder is 11 after subtracting 160 from 171.
Include the next digit (4) from the dividend after 11, then repeat: 114 / 20

On to step 4:
The number 20 fits into 114 5 times, leaving a remainder of 14.
Record the quotient 5 as the next digit in the result. 
Result so far: 485.0
Deduct 100 from 114 and we're left with 14.
Fetch the next digit (2) from the dividend, attach it to 14 and continue: 142 / 20

Moving on to step 5:
20 can be fit into 142 7 times, resulting in a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 4857.0
Subtracting 140 from 142 leaves us with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 20

Moving on to step 6:
When dividing 23 by 20, we get 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 48571.0
Subtracting 20 from 23 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
When dividing 30 by 20, we get 1 with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 48571.1
Subtract 20 from 30 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:
20 goes into 100 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 48571.15
If we take 100 away from 100, 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.

Advancing to step 9:
20 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 48571.15
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.
Record the quotient 0 as the next digit in the result. 
Result so far: 48571.15
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.

After the division, we end up with 48571.15 and a remainder of 0.0.
