We divide 80665 by 97
The aim is to understand the frequency of 97 in 80665.

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
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 97

Let's proceed to step 2:
If we divide 80 by 97, we get 0 and a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Append the next digit (6) from the dividend to 80 and continue with: 806 / 97

On to step 3:
The number 97 fits into 806 8 times, leaving a remainder of 30.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 776 from 806 to get 30.
Append the next digit (6) from the dividend to 30 and continue with: 306 / 97

Moving on to step 4:
The number 97 fits into 306 3 times, leaving a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 83.0
Subtract 291 from 306 to get 15.
Bring next digit (5) of the dividend behind the 15 and repeat the process: 155 / 97

Moving on to step 5:
If we divide 155 by 97, we get 1 and a remainder of 58.
The number 1 becomes the next digit in our result. 
Result so far: 831.0
The remainder is 58 after subtracting 97 from 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 6:
97 goes into 580 5 times with a remainder of 95.
Write down 5 as next digit of the result. 
Result so far: 831.5
If we subtract 485 from 580, we get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Advancing to step 7:
If we divide 950 by 97, we get 9 and a remainder of 77.
Put 9 as the next digit of the answer. 
Result so far: 831.59
If we subtract 873 from 950, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 8:
When dividing 770 by 97, we get 7 with a remainder of 91.
Write down 7 as next digit of the result. 
Result so far: 831.597
Subtracting 679 from 770 leaves us with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

On to step 9:
97 goes into 910 9 times with a remainder of 37.
Put 9 as the next digit of the answer. 
Result so far: 831.5979
The remainder is 37 after subtracting 873 from 910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 10:
If we divide 370 by 97, we get 3 and a remainder of 79.
Write down 3 as next digit of the result. 
Result so far: 831.59793
Subtract 291 from 370 to get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 11:
When dividing 790 by 97, we get 8 with a remainder of 14.
The next digit of our result is 8. 
Result so far: 831.597938
Subtract 776 from 790 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 12:
The number 97 fits into 140 1 times, leaving a remainder of 43.
The next digit of our result is 1. 
Result so far: 831.5979381
If we subtract 97 from 140, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 13:
430 divided by 97 is 4 with a remainder of 42.
Write down 4 as next digit of the result. 
Result so far: 831.59793814
Deduct 388 from 430 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final outcome is 831.59793814, with a leftover of 4.2e-08.
