697976 ÷ 20 
The aim is to understand the frequency of 20 in 697976.

Advancing to step 1:
The number 20 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 20

Moving on to step 2:
The number 20 fits into 69 3 times, leaving a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 60 from 69 leaves us with 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 20

Moving on to step 3:
20 goes into 97 4 times with a remainder of 17.
Use 4 as the next digit of our solution. 
Result so far: 34.0
Subtract 80 from 97 to get 17.
Fetch the next digit (9) from the dividend, attach it to 17 and continue: 179 / 20

On to step 4:
20 goes into 179 8 times with a remainder of 19.
Put 8 as the next digit of the answer. 
Result so far: 348.0
Subtract 160 from 179 to get 19.
Include the next digit (7) from the dividend after 19, then repeat: 197 / 20

On to step 5:
20 can be fit into 197 9 times, resulting in a remainder of 17.
The next digit of our result is 9. 
Result so far: 3489.0
If we subtract 180 from 197, we get 17.
Bring next digit (6) of the dividend behind the 17 and repeat the process: 176 / 20

Step 6:
The number 20 fits into 176 8 times, leaving a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 34898.0
If we subtract 160 from 176, we 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.

Let's proceed to step 7:
160 divided by 20 is 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 34898.8
Subtracting 160 from 160 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.

Moving on to step 8:
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: 34898.8
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.

On to step 9:
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: 34898.8
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.

After the division, we end up with 34898.8 and a remainder of 0.0.
