We look at the division of 81517187 by 127 
The aim is to understand the frequency of 127 in 81517187.

Let's proceed to step 1:
When dividing 8 by 127, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 127

Advancing to step 2:
127 goes into 81 0 times with a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Append the next digit (5) from the dividend to 81 and continue with: 815 / 127

Advancing to step 3:
127 goes into 815 6 times with a remainder of 53.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 762 from 815 leaves us with 53.
Take the next digit (1) from the dividend and append it to 53, then repeat: 531 / 127

Let's proceed to step 4:
If we divide 531 by 127, we get 4 and a remainder of 23.
The next digit of our result is 4. 
Result so far: 64.0
Deduct 508 from 531 and we're left with 23.
Fetch the next digit (7) from the dividend, attach it to 23 and continue: 237 / 127

Let's proceed to step 5:
127 goes into 237 1 times with a remainder of 110.
Put 1 as the next digit of the answer. 
Result so far: 641.0
Subtract 127 from 237 to get 110.
Take the next digit (1) from the dividend and append it to 110, then repeat: 1101 / 127

On to step 6:
If we divide 1101 by 127, we get 8 and a remainder of 85.
The next digit of our result is 8. 
Result so far: 6418.0
If we take 1016 away from 1101, we end up with 85.
Fetch the next digit (8) from the dividend, attach it to 85 and continue: 858 / 127

Going ahead to step 7:
If we divide 858 by 127, we get 6 and a remainder of 96.
Put 6 as the next digit of the answer. 
Result so far: 64186.0
If we take 762 away from 858, we end up with 96.
Grab the next digit (7) from the dividend, add it to 96, then carry on: 967 / 127

Step 8:
127 goes into 967 7 times with a remainder of 78.
Use 7 as the next digit of our solution. 
Result so far: 641867.0
If we subtract 889 from 967, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 9:
When dividing 780 by 127, we get 6 with a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 641867.6
If we subtract 762 from 780, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 10:
The number 127 fits into 180 1 times, leaving a remainder of 53.
The number 1 becomes the next digit in our result. 
Result so far: 641867.61
Deduct 127 from 180 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 11:
530 divided by 127 is 4 with a remainder of 22.
Record the quotient 4 as the next digit in the result. 
Result so far: 641867.614
If we take 508 away from 530, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 12:
When dividing 220 by 127, we get 1 with a remainder of 93.
The next digit of our result is 1. 
Result so far: 641867.6141
Deduct 127 from 220 and we're left with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Advancing to step 13:
127 can be fit into 930 7 times, resulting in a remainder of 41.
Put 7 as the next digit of the answer. 
Result so far: 641867.61417
Subtracting 889 from 930 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 14:
If we divide 410 by 127, we get 3 and a remainder of 29.
Write down 3 as next digit of the result. 
Result so far: 641867.614173
Deduct 381 from 410 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 15:
If we divide 290 by 127, we get 2 and a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 641867.6141732
Subtract 254 from 290 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 16:
If we divide 360 by 127, we get 2 and a remainder of 106.
The number 2 becomes the next digit in our result. 
Result so far: 641867.61417322
If we subtract 254 from 360, we get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

In conclusion, the division gives 641867.61417322 with a balance of 1.06e-07.
