We look at the division of 622621 by 97 
The aim is to understand the frequency of 97 in 622621.

Advancing to step 1:
If we divide 6 by 97, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 97

Step 2:
97 can be fit into 62 0 times, resulting in a remainder of 62.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 62 to get 62.
Fetch the next digit (2) from the dividend, attach it to 62 and continue: 622 / 97

Going ahead to step 3:
97 can be fit into 622 6 times, resulting in a remainder of 40.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 582 from 622 to get 40.
Take the next digit (6) from the dividend and append it to 40, then repeat: 406 / 97

Going ahead to step 4:
The number 97 fits into 406 4 times, leaving a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 64.0
Subtracting 388 from 406 leaves us with 18.
Append the next digit (2) from the dividend to 18 and continue with: 182 / 97

Step 5:
If we divide 182 by 97, we get 1 and a remainder of 85.
Record the quotient 1 as the next digit in the result. 
Result so far: 641.0
The remainder is 85 after subtracting 97 from 182.
Include the next digit (1) from the dividend after 85, then repeat: 851 / 97

Moving on to step 6:
If we divide 851 by 97, we get 8 and a remainder of 75.
The number 8 becomes the next digit in our result. 
Result so far: 6418.0
If we subtract 776 from 851, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 7:
If we divide 750 by 97, we get 7 and a remainder of 71.
Use 7 as the next digit of our solution. 
Result so far: 6418.7
The remainder is 71 after subtracting 679 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 8:
When dividing 710 by 97, we get 7 with a remainder of 31.
Record the quotient 7 as the next digit in the result. 
Result so far: 6418.77
If we subtract 679 from 710, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

The final outcome is 6418.77, with a leftover of 0.031.
