We look at the division of 81612076 by 97 
The aim is to understand the frequency of 97 in 81612076.

Going ahead to step 1:
If we divide 8 by 97, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 97

Step 2:
81 divided by 97 is 0 with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Include the next digit (6) from the dividend after 81, then repeat: 816 / 97

Moving on to step 3:
The number 97 fits into 816 8 times, leaving a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 776 from 816 to get 40.
Fetch the next digit (1) from the dividend, attach it to 40 and continue: 401 / 97

Advancing to step 4:
If we divide 401 by 97, we get 4 and a remainder of 13.
Write down 4 as next digit of the result. 
Result so far: 84.0
Subtracting 388 from 401 leaves us with 13.
Grab the next digit (2) from the dividend, add it to 13, then carry on: 132 / 97

Going ahead to step 5:
If we divide 132 by 97, we get 1 and a remainder of 35.
The next digit of our result is 1. 
Result so far: 841.0
Subtract 97 from 132 to get 35.
Take the next digit (0) from the dividend and append it to 35, then repeat: 350 / 97

On to step 6:
350 divided by 97 is 3 with a remainder of 59.
Put 3 as the next digit of the answer. 
Result so far: 8413.0
If we subtract 291 from 350, we get 59.
Fetch the next digit (7) from the dividend, attach it to 59 and continue: 597 / 97

Moving on to step 7:
If we divide 597 by 97, we get 6 and a remainder of 15.
Use 6 as the next digit of our solution. 
Result so far: 84136.0
If we subtract 582 from 597, we get 15.
Take the next digit (6) from the dividend and append it to 15, then repeat: 156 / 97

On to step 8:
When dividing 156 by 97, we get 1 with a remainder of 59.
The next digit of our result is 1. 
Result so far: 841361.0
If we subtract 97 from 156, we 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 9:
590 divided by 97 is 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 841361.6
If we subtract 582 from 590, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
80 divided by 97 is 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 841361.6
Subtracting 0 from 80 leaves us with 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 11:
When dividing 800 by 97, we get 8 with a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 841361.608
If we take 776 away from 800, we end up 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.

Advancing to step 12:
The number 97 fits into 240 2 times, leaving a remainder of 46.
Write down 2 as next digit of the result. 
Result so far: 841361.6082
Subtract 194 from 240 to 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.

Moving on to step 13:
If we divide 460 by 97, we get 4 and a remainder of 72.
The next digit of our result is 4. 
Result so far: 841361.60824
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.

Advancing to step 14:
When dividing 720 by 97, we get 7 with a remainder of 41.
Record the quotient 7 as the next digit in the result. 
Result so far: 841361.608247
If we subtract 679 from 720, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 15:
410 divided by 97 is 4 with a remainder of 22.
The next digit of our result is 4. 
Result so far: 841361.6082474
Subtract 388 from 410 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 16:
When dividing 220 by 97, we get 2 with a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 841361.60824742
The remainder is 26 after subtracting 194 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

After the division, we end up with 841361.60824742 and a remainder of 2.6e-08.
