We look at the division of 528209 by 97 
The aim is to understand the frequency of 97 in 528209.

Advancing to step 1:
The number 97 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 97

Moving on to step 2:
When dividing 52 by 97, we get 0 with a remainder of 52.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 52 to get 52.
Fetch the next digit (8) from the dividend, attach it to 52 and continue: 528 / 97

On to step 3:
97 can be fit into 528 5 times, resulting in a remainder of 43.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 485 from 528 leaves us with 43.
Fetch the next digit (2) from the dividend, attach it to 43 and continue: 432 / 97

Let's proceed to step 4:
If we divide 432 by 97, we get 4 and a remainder of 44.
The number 4 becomes the next digit in our result. 
Result so far: 54.0
If we take 388 away from 432, we end up with 44.
Take the next digit (0) from the dividend and append it to 44, then repeat: 440 / 97

Advancing to step 5:
440 divided by 97 is 4 with a remainder of 52.
The next digit of our result is 4. 
Result so far: 544.0
The remainder is 52 after subtracting 388 from 440.
Fetch the next digit (9) from the dividend, attach it to 52 and continue: 529 / 97

Going ahead to step 6:
If we divide 529 by 97, we get 5 and a remainder of 44.
Put 5 as the next digit of the answer. 
Result so far: 5445.0
If we subtract 485 from 529, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 7:
If we divide 440 by 97, we get 4 and a remainder of 52.
Use 4 as the next digit of our solution. 
Result so far: 5445.4
Deduct 388 from 440 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 8:
97 goes into 520 5 times with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 5445.45
Subtracting 485 from 520 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 9:
350 divided by 97 is 3 with a remainder of 59.
Use 3 as the next digit of our solution. 
Result so far: 5445.453
Deduct 291 from 350 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 10:
97 goes into 590 6 times with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 5445.4536
Deduct 582 from 590 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 11:
97 goes into 80 0 times with a remainder of 80.
The next digit of our result is 0. 
Result so far: 5445.4536
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 12:
97 goes into 800 8 times with a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 5445.453608
The remainder is 24 after subtracting 776 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 13:
97 can be fit into 240 2 times, resulting in a remainder of 46.
Use 2 as the next digit of our solution. 
Result so far: 5445.4536082
If we subtract 194 from 240, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 14:
When dividing 460 by 97, we get 4 with a remainder of 72.
Write down 4 as next digit of the result. 
Result so far: 5445.45360824
Subtract 388 from 460 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final outcome is 5445.45360824, with a leftover of 7.2e-08.
