We look at the division of 990251 by 97 
The aim is to understand the frequency of 97 in 990251.

Moving on to step 1:
When dividing 9 by 97, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 97

Moving on to step 2:
99 divided by 97 is 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 97 from 99 to get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 97

Going ahead to step 3:
97 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 20 after subtracting 0 from 20.
Append the next digit (2) from the dividend to 20 and continue with: 202 / 97

Going ahead to step 4:
If we divide 202 by 97, we get 2 and a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 102.0
If we take 194 away from 202, we end up with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 97

Let's proceed to step 5:
97 goes into 85 0 times with a remainder of 85.
Use 0 as the next digit of our solution. 
Result so far: 1020.0
Subtract 0 from 85 to get 85.
Bring next digit (1) of the dividend behind the 85 and repeat the process: 851 / 97

Moving on to step 6:
When dividing 851 by 97, we get 8 with a remainder of 75.
Use 8 as the next digit of our solution. 
Result so far: 10208.0
The remainder is 75 after subtracting 776 from 851.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 7:
When dividing 750 by 97, we get 7 with a remainder of 71.
Use 7 as the next digit of our solution. 
Result so far: 10208.7
Subtract 679 from 750 to get 71.
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:
If we divide 710 by 97, we get 7 and a remainder of 31.
Use 7 as the next digit of our solution. 
Result so far: 10208.77
Subtract 679 from 710 to 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 10208.77, with a leftover of 0.031.
