214117 divided by 91 
The aim is to understand the frequency of 91 in 214117.

Moving on 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
If we take 0 away from 2, we end up with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 91

Advancing to step 2:
If we divide 21 by 91, we get 0 and a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Fetch the next digit (4) from the dividend, attach it to 21 and continue: 214 / 91

Going ahead to step 3:
If we divide 214 by 91, we get 2 and a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 182 from 214 to get 32.
Bring next digit (1) of the dividend behind the 32 and repeat the process: 321 / 91

Moving on to step 4:
91 can be fit into 321 3 times, resulting in a remainder of 48.
Use 3 as the next digit of our solution. 
Result so far: 23.0
Subtracting 273 from 321 leaves us with 48.
Bring next digit (1) of the dividend behind the 48 and repeat the process: 481 / 91

Going ahead to step 5:
If we divide 481 by 91, we get 5 and a remainder of 26.
Use 5 as the next digit of our solution. 
Result so far: 235.0
The remainder is 26 after subtracting 455 from 481.
Take the next digit (7) from the dividend and append it to 26, then repeat: 267 / 91

Advancing to step 6:
91 goes into 267 2 times with a remainder of 85.
Write down 2 as next digit of the result. 
Result so far: 2352.0
Subtract 182 from 267 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 7:
91 can be fit into 850 9 times, resulting in a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 2352.9
If we subtract 819 from 850, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 8:
If we divide 310 by 91, we get 3 and a remainder of 37.
The next digit of our result is 3. 
Result so far: 2352.93
Subtracting 273 from 310 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 9:
If we divide 370 by 91, we get 4 and a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 2352.934
The remainder is 6 after subtracting 364 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 10:
60 divided by 91 is 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 2352.934
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 11:
When dividing 600 by 91, we get 6 with a remainder of 54.
Put 6 as the next digit of the answer. 
Result so far: 2352.93406
The remainder is 54 after subtracting 546 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 12:
91 goes into 540 5 times with a remainder of 85.
Use 5 as the next digit of our solution. 
Result so far: 2352.934065
If we subtract 455 from 540, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Advancing to step 13:
91 can be fit into 850 9 times, resulting in a remainder of 31.
Record the quotient 9 as the next digit in the result. 
Result so far: 2352.9340659
If we subtract 819 from 850, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 14:
The number 91 fits into 310 3 times, leaving a remainder of 37.
Use 3 as the next digit of our solution. 
Result so far: 2352.93406593
Subtract 273 from 310 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

The final outcome is 2352.93406593, with a leftover of 3.7e-08.
