We look at the division of 903770 by 97 
The aim is to understand the frequency of 97 in 903770.

On to step 1:
97 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 97

Moving on to step 2:
When dividing 90 by 97, we get 0 with a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 90 leaves us with 90.
Bring next digit (3) of the dividend behind the 90 and repeat the process: 903 / 97

Step 3:
97 can be fit into 903 9 times, resulting in a remainder of 30.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 873 away from 903, we end up with 30.
Append the next digit (7) from the dividend to 30 and continue with: 307 / 97

Going ahead to step 4:
If we divide 307 by 97, we get 3 and a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 93.0
If we subtract 291 from 307, we get 16.
Fetch the next digit (7) from the dividend, attach it to 16 and continue: 167 / 97

Advancing to step 5:
When dividing 167 by 97, we get 1 with a remainder of 70.
Use 1 as the next digit of our solution. 
Result so far: 931.0
If we subtract 97 from 167, we get 70.
Fetch the next digit (0) from the dividend, attach it to 70 and continue: 700 / 97

On to step 6:
700 divided by 97 is 7 with a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 9317.0
Subtract 679 from 700 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 7:
The number 97 fits into 210 2 times, leaving a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 9317.2
Subtract 194 from 210 to 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.

Step 8:
When dividing 160 by 97, we get 1 with a remainder of 63.
Put 1 as the next digit of the answer. 
Result so far: 9317.21
Deduct 97 from 160 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 9:
630 divided by 97 is 6 with a remainder of 48.
The next digit of our result is 6. 
Result so far: 9317.216
The remainder is 48 after subtracting 582 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 10:
97 goes into 480 4 times with a remainder of 92.
Use 4 as the next digit of our solution. 
Result so far: 9317.2164
Subtract 388 from 480 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Going ahead to step 11:
When dividing 920 by 97, we get 9 with a remainder of 47.
Put 9 as the next digit of the answer. 
Result so far: 9317.21649
If we subtract 873 from 920, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 12:
97 can be fit into 470 4 times, resulting in a remainder of 82.
Use 4 as the next digit of our solution. 
Result so far: 9317.216494
If we take 388 away from 470, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Step 13:
The number 97 fits into 820 8 times, leaving a remainder of 44.
Use 8 as the next digit of our solution. 
Result so far: 9317.2164948
Deduct 776 from 820 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 14:
97 can be fit into 440 4 times, resulting in a remainder of 52.
Use 4 as the next digit of our solution. 
Result so far: 9317.21649484
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.

The final result is 9317.21649484 with a remainder of 5.2e-08.
