314091 ÷ 91 
The aim is to understand the frequency of 91 in 314091.

Advancing to step 1:
3 divided by 91 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 91

Let's proceed to step 2:
91 goes into 31 0 times with a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Include the next digit (4) from the dividend after 31, then repeat: 314 / 91

Moving on to step 3:
When dividing 314 by 91, we get 3 with a remainder of 41.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 273 from 314 leaves us with 41.
Take the next digit (0) from the dividend and append it to 41, then repeat: 410 / 91

Let's proceed to step 4:
91 goes into 410 4 times with a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 34.0
Subtract 364 from 410 to get 46.
Take the next digit (9) from the dividend and append it to 46, then repeat: 469 / 91

Moving on to step 5:
91 goes into 469 5 times with a remainder of 14.
The next digit of our result is 5. 
Result so far: 345.0
Subtracting 455 from 469 leaves us with 14.
Bring next digit (1) of the dividend behind the 14 and repeat the process: 141 / 91

Going ahead to step 6:
When dividing 141 by 91, we get 1 with a remainder of 50.
Record the quotient 1 as the next digit in the result. 
Result so far: 3451.0
If we subtract 91 from 141, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 7:
The number 91 fits into 500 5 times, leaving a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 3451.5
Subtract 455 from 500 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 8:
450 divided by 91 is 4 with a remainder of 86.
Write down 4 as next digit of the result. 
Result so far: 3451.54
Subtract 364 from 450 to get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Going ahead to step 9:
The number 91 fits into 860 9 times, leaving a remainder of 41.
The next digit of our result is 9. 
Result so far: 3451.549
The remainder is 41 after subtracting 819 from 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 10:
91 goes into 410 4 times with a remainder of 46.
The next digit of our result is 4. 
Result so far: 3451.5494
If we subtract 364 from 410, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 11:
When dividing 460 by 91, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 3451.54945
If we subtract 455 from 460, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 12:
50 divided by 91 is 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 3451.54945
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 13:
If we divide 500 by 91, we get 5 and a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 3451.5494505
Subtracting 455 from 500 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 14:
If we divide 450 by 91, we get 4 and a remainder of 86.
Write down 4 as next digit of the result. 
Result so far: 3451.54945054
The remainder is 86 after subtracting 364 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

After the division, we end up with 3451.54945054 and a remainder of 8.6e-08.
