91777965 divided by 127 
The aim is to understand the frequency of 127 in 91777965.

Step 1:
127 can be fit into 9 0 times, resulting in a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 127

Let's proceed to step 2:
The number 127 fits into 91 0 times, leaving a remainder of 91.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 91 to get 91.
Fetch the next digit (7) from the dividend, attach it to 91 and continue: 917 / 127

Step 3:
127 can be fit into 917 7 times, resulting in a remainder of 28.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 889 from 917 leaves us with 28.
Take the next digit (7) from the dividend and append it to 28, then repeat: 287 / 127

Let's proceed to step 4:
If we divide 287 by 127, we get 2 and a remainder of 33.
The number 2 becomes the next digit in our result. 
Result so far: 72.0
The remainder is 33 after subtracting 254 from 287.
Fetch the next digit (7) from the dividend, attach it to 33 and continue: 337 / 127

On to step 5:
When dividing 337 by 127, we get 2 with a remainder of 83.
Write down 2 as next digit of the result. 
Result so far: 722.0
If we take 254 away from 337, we end up with 83.
Take the next digit (9) from the dividend and append it to 83, then repeat: 839 / 127

Advancing to step 6:
127 goes into 839 6 times with a remainder of 77.
Write down 6 as next digit of the result. 
Result so far: 7226.0
Subtracting 762 from 839 leaves us with 77.
Include the next digit (6) from the dividend after 77, then repeat: 776 / 127

Let's proceed to step 7:
If we divide 776 by 127, we get 6 and a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 72266.0
Subtracting 762 from 776 leaves us with 14.
Bring next digit (5) of the dividend behind the 14 and repeat the process: 145 / 127

On to step 8:
When dividing 145 by 127, we get 1 with a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 722661.0
Subtracting 127 from 145 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 9:
127 can be fit into 180 1 times, resulting in a remainder of 53.
The number 1 becomes the next digit in our result. 
Result so far: 722661.1
Subtract 127 from 180 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 10:
127 goes into 530 4 times with a remainder of 22.
Put 4 as the next digit of the answer. 
Result so far: 722661.14
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.

Going ahead to step 11:
If we divide 220 by 127, we get 1 and a remainder of 93.
The next digit of our result is 1. 
Result so far: 722661.141
If we take 127 away from 220, we end up 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 12:
If we divide 930 by 127, we get 7 and a remainder of 41.
Use 7 as the next digit of our solution. 
Result so far: 722661.1417
If we take 889 away from 930, we end up 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.

Going ahead to step 13:
The number 127 fits into 410 3 times, leaving a remainder of 29.
The number 3 becomes the next digit in our result. 
Result so far: 722661.14173
The remainder is 29 after subtracting 381 from 410.
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 14:
290 divided by 127 is 2 with a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 722661.141732
Subtracting 254 from 290 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 15:
When dividing 360 by 127, we get 2 with a remainder of 106.
The next digit of our result is 2. 
Result so far: 722661.1417322
If we take 254 away from 360, we end up with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

After the division, we end up with 722661.1417322 and a remainder of 1.06e-06.
