We look at the division of 68662797 by 20 
The aim is to understand the frequency of 20 in 68662797.

Going ahead to step 1:
The number 20 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 20

Moving on to step 2:
If we divide 68 by 20, we get 3 and a remainder of 8.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 60 from 68 and we're left with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 20

On to step 3:
20 can be fit into 86 4 times, resulting in a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 34.0
Deduct 80 from 86 and we're left with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 20

Step 4:
When dividing 66 by 20, we get 3 with a remainder of 6.
The next digit of our result is 3. 
Result so far: 343.0
Subtract 60 from 66 to get 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 20

Going ahead to step 5:
The number 20 fits into 62 3 times, leaving a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 3433.0
Subtract 60 from 62 to get 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 20

Moving on to step 6:
If we divide 27 by 20, we get 1 and a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 34331.0
If we subtract 20 from 27, we get 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 20

Let's proceed to step 7:
79 divided by 20 is 3 with a remainder of 19.
Put 3 as the next digit of the answer. 
Result so far: 343313.0
Subtracting 60 from 79 leaves us with 19.
Fetch the next digit (7) from the dividend, attach it to 19 and continue: 197 / 20

Going ahead to step 8:
The number 20 fits into 197 9 times, leaving a remainder of 17.
Use 9 as the next digit of our solution. 
Result so far: 3433139.0
If we take 180 away from 197, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 9:
The number 20 fits into 170 8 times, leaving a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 3433139.8
If we subtract 160 from 170, we 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.

Moving on to step 10:
20 goes into 100 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 3433139.85
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.

On to step 11:
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: 3433139.85
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.

Step 12:
If we divide 0 by 20, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3433139.85
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.

The quotient of the division is 3433139.85, and the remainder is 0.0.
