Let's divide 866739 by 97
The aim is to understand the frequency of 97 in 866739.

Going ahead to step 1:
The number 97 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 97

Advancing to step 2:
When dividing 86 by 97, we get 0 with a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Fetch the next digit (6) from the dividend, attach it to 86 and continue: 866 / 97

Going ahead to step 3:
When dividing 866 by 97, we get 8 with a remainder of 90.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 776 from 866 leaves us with 90.
Fetch the next digit (7) from the dividend, attach it to 90 and continue: 907 / 97

Advancing to step 4:
If we divide 907 by 97, we get 9 and a remainder of 34.
Record the quotient 9 as the next digit in the result. 
Result so far: 89.0
Subtract 873 from 907 to get 34.
Include the next digit (3) from the dividend after 34, then repeat: 343 / 97

On to step 5:
If we divide 343 by 97, we get 3 and a remainder of 52.
The next digit of our result is 3. 
Result so far: 893.0
If we subtract 291 from 343, we get 52.
Grab the next digit (9) from the dividend, add it to 52, then carry on: 529 / 97

Step 6:
97 can be fit into 529 5 times, resulting in a remainder of 44.
Put 5 as the next digit of the answer. 
Result so far: 8935.0
Deduct 485 from 529 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.

On to step 7:
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: 8935.4
Subtracting 388 from 440 leaves us 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.

Going ahead to step 8:
520 divided by 97 is 5 with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 8935.45
If we take 485 away from 520, we end up 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.

Moving on to step 9:
If we divide 350 by 97, we get 3 and a remainder of 59.
Write down 3 as next digit of the result. 
Result so far: 8935.453
Subtract 291 from 350 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 10:
The number 97 fits into 590 6 times, leaving a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 8935.4536
Subtracting 582 from 590 leaves us 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.

Step 11:
80 divided by 97 is 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 8935.4536
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 12:
800 divided by 97 is 8 with a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 8935.453608
Subtracting 776 from 800 leaves us with 24.
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:
If we divide 240 by 97, we get 2 and a remainder of 46.
Use 2 as the next digit of our solution. 
Result so far: 8935.4536082
The remainder is 46 after subtracting 194 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 14:
The number 97 fits into 460 4 times, leaving a remainder of 72.
The next digit of our result is 4. 
Result so far: 8935.45360824
Subtracting 388 from 460 leaves us with 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 8935.45360824, with a leftover of 7.2e-08.
