We look at the division of 277655 by 91 
The aim is to understand the frequency of 91 in 277655.

Let's proceed to step 1:
If we divide 2 by 91, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 91

Let's proceed to step 2:
If we divide 27 by 91, we get 0 and a remainder of 27.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 27 after subtracting 0 from 27.
Include the next digit (7) from the dividend after 27, then repeat: 277 / 91

Going ahead to step 3:
277 divided by 91 is 3 with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 273 from 277, we get 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 91

Step 4:
The number 91 fits into 46 0 times, leaving a remainder of 46.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
If we take 0 away from 46, we end up with 46.
Append the next digit (5) from the dividend to 46 and continue with: 465 / 91

Going ahead to step 5:
If we divide 465 by 91, we get 5 and a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 305.0
If we subtract 455 from 465, we get 10.
Fetch the next digit (5) from the dividend, attach it to 10 and continue: 105 / 91

Advancing to step 6:
105 divided by 91 is 1 with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 3051.0
Subtracting 91 from 105 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 7:
When dividing 140 by 91, we get 1 with a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 3051.1
Deduct 91 from 140 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 8:
When dividing 490 by 91, we get 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 3051.15
The remainder is 35 after subtracting 455 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 9:
When dividing 350 by 91, we get 3 with a remainder of 77.
Use 3 as the next digit of our solution. 
Result so far: 3051.153
If we take 273 away from 350, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 10:
The number 91 fits into 770 8 times, leaving a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 3051.1538
Deduct 728 from 770 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 11:
420 divided by 91 is 4 with a remainder of 56.
The next digit of our result is 4. 
Result so far: 3051.15384
The remainder is 56 after subtracting 364 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 12:
If we divide 560 by 91, we get 6 and a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 3051.153846
Subtracting 546 from 560 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 13:
When dividing 140 by 91, we get 1 with a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 3051.1538461
The remainder is 49 after subtracting 91 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 14:
When dividing 490 by 91, we get 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 3051.15384615
Subtracting 455 from 490 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

In conclusion, the division gives 3051.15384615 with a balance of 3.5e-08.
