We divide 81297663 by 128
The aim is to understand the frequency of 128 in 81297663.

On to step 1:
If we divide 8 by 128, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 128

Let's proceed to step 2:
If we divide 81 by 128, we get 0 and a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Bring next digit (2) of the dividend behind the 81 and repeat the process: 812 / 128

On to step 3:
The number 128 fits into 812 6 times, leaving a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 768 from 812 and we're left with 44.
Take the next digit (9) from the dividend and append it to 44, then repeat: 449 / 128

Going ahead to step 4:
128 goes into 449 3 times with a remainder of 65.
The next digit of our result is 3. 
Result so far: 63.0
If we take 384 away from 449, we end up with 65.
Include the next digit (7) from the dividend after 65, then repeat: 657 / 128

Let's proceed to step 5:
128 can be fit into 657 5 times, resulting in a remainder of 17.
The number 5 becomes the next digit in our result. 
Result so far: 635.0
Subtract 640 from 657 to get 17.
Include the next digit (6) from the dividend after 17, then repeat: 176 / 128

Going ahead to step 6:
128 goes into 176 1 times with a remainder of 48.
The number 1 becomes the next digit in our result. 
Result so far: 6351.0
Subtracting 128 from 176 leaves us with 48.
Bring next digit (6) of the dividend behind the 48 and repeat the process: 486 / 128

On to step 7:
486 divided by 128 is 3 with a remainder of 102.
The number 3 becomes the next digit in our result. 
Result so far: 63513.0
Subtracting 384 from 486 leaves us with 102.
Append the next digit (3) from the dividend to 102 and continue with: 1023 / 128

Advancing to step 8:
When dividing 1023 by 128, we get 7 with a remainder of 127.
Put 7 as the next digit of the answer. 
Result so far: 635137.0
If we take 896 away from 1023, we end up with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Moving on to step 9:
1270 divided by 128 is 9 with a remainder of 118.
Record the quotient 9 as the next digit in the result. 
Result so far: 635137.9
Subtract 1152 from 1270 to get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Step 10:
The number 128 fits into 1180 9 times, leaving a remainder of 28.
Put 9 as the next digit of the answer. 
Result so far: 635137.99
Subtracting 1152 from 1180 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final result is 635137.99 with a remainder of 0.028.
