We're dividing 427697 by 20 
The aim is to understand the frequency of 20 in 427697.

Advancing to step 1:
20 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 20

Moving on to step 2:
If we divide 42 by 20, we get 2 and a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 40 from 42, we get 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 20

On to step 3:
20 goes into 27 1 times with a remainder of 7.
The next digit of our result is 1. 
Result so far: 21.0
If we subtract 20 from 27, we get 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 20

Going ahead to step 4:
The number 20 fits into 76 3 times, leaving a remainder of 16.
The next digit of our result is 3. 
Result so far: 213.0
Subtract 60 from 76 to get 16.
Fetch the next digit (9) from the dividend, attach it to 16 and continue: 169 / 20

Moving on to step 5:
169 divided by 20 is 8 with a remainder of 9.
Record the quotient 8 as the next digit in the result. 
Result so far: 2138.0
Subtract 160 from 169 to get 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 20

On to step 6:
If we divide 97 by 20, we get 4 and a remainder of 17.
Put 4 as the next digit of the answer. 
Result so far: 21384.0
The remainder is 17 after subtracting 80 from 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 7:
If we divide 170 by 20, we get 8 and a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 21384.8
Deduct 160 from 170 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.

Going ahead to step 8:
100 divided by 20 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 21384.85
Deduct 100 from 100 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.

Step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 21384.85
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.

On to step 10:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 21384.85
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 21384.85, with a leftover of 0.0.
