80591315 ÷ 128 
The aim is to understand the frequency of 128 in 80591315.

Advancing to step 1:
128 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 128

Let's proceed to step 2:
80 divided by 128 is 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Fetch the next digit (5) from the dividend, attach it to 80 and continue: 805 / 128

Let's proceed to step 3:
When dividing 805 by 128, we get 6 with a remainder of 37.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 768 from 805 and we're left with 37.
Take the next digit (9) from the dividend and append it to 37, then repeat: 379 / 128

Let's proceed to step 4:
If we divide 379 by 128, we get 2 and a remainder of 123.
The next digit of our result is 2. 
Result so far: 62.0
Deduct 256 from 379 and we're left with 123.
Fetch the next digit (1) from the dividend, attach it to 123 and continue: 1231 / 128

Step 5:
The number 128 fits into 1231 9 times, leaving a remainder of 79.
Write down 9 as next digit of the result. 
Result so far: 629.0
Subtracting 1152 from 1231 leaves us with 79.
Append the next digit (3) from the dividend to 79 and continue with: 793 / 128

Step 6:
The number 128 fits into 793 6 times, leaving a remainder of 25.
Record the quotient 6 as the next digit in the result. 
Result so far: 6296.0
Deduct 768 from 793 and we're left with 25.
Append the next digit (1) from the dividend to 25 and continue with: 251 / 128

Let's proceed to step 7:
The number 128 fits into 251 1 times, leaving a remainder of 123.
The number 1 becomes the next digit in our result. 
Result so far: 62961.0
If we take 128 away from 251, we end up with 123.
Bring next digit (5) of the dividend behind the 123 and repeat the process: 1235 / 128

Advancing to step 8:
If we divide 1235 by 128, we get 9 and a remainder of 83.
Put 9 as the next digit of the answer. 
Result so far: 629619.0
If we subtract 1152 from 1235, we get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Going ahead to step 9:
830 divided by 128 is 6 with a remainder of 62.
Write down 6 as next digit of the result. 
Result so far: 629619.6
The remainder is 62 after subtracting 768 from 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 10:
620 divided by 128 is 4 with a remainder of 108.
Use 4 as the next digit of our solution. 
Result so far: 629619.64
If we subtract 512 from 620, we get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Step 11:
The number 128 fits into 1080 8 times, leaving a remainder of 56.
Write down 8 as next digit of the result. 
Result so far: 629619.648
Subtracting 1024 from 1080 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 12:
128 goes into 560 4 times with a remainder of 48.
The next digit of our result is 4. 
Result so far: 629619.6484
Subtracting 512 from 560 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 13:
480 divided by 128 is 3 with a remainder of 96.
Use 3 as the next digit of our solution. 
Result so far: 629619.64843
If we take 384 away from 480, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 14:
128 goes into 960 7 times with a remainder of 64.
The number 7 becomes the next digit in our result. 
Result so far: 629619.648437
If we take 896 away from 960, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 15:
When dividing 640 by 128, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 629619.6484375
Deduct 640 from 640 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 16:
128 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 629619.6484375
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 629619.6484375 and a remainder of 0.0.
