We're dividing 50750 by 91 
The aim is to understand the frequency of 91 in 50750.

Let's proceed to step 1:
If we divide 5 by 91, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 91

On to step 2:
91 goes into 50 0 times with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 50, we end up with 50.
Bring next digit (7) of the dividend behind the 50 and repeat the process: 507 / 91

Let's proceed to step 3:
507 divided by 91 is 5 with a remainder of 52.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 455 away from 507, we end up with 52.
Take the next digit (5) from the dividend and append it to 52, then repeat: 525 / 91

Moving on to step 4:
When dividing 525 by 91, we get 5 with a remainder of 70.
The next digit of our result is 5. 
Result so far: 55.0
If we subtract 455 from 525, we get 70.
Fetch the next digit (0) from the dividend, attach it to 70 and continue: 700 / 91

Going ahead to step 5:
When dividing 700 by 91, we get 7 with a remainder of 63.
The next digit of our result is 7. 
Result so far: 557.0
Subtract 637 from 700 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 6:
If we divide 630 by 91, we get 6 and a remainder of 84.
Put 6 as the next digit of the answer. 
Result so far: 557.6
If we subtract 546 from 630, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 7:
The number 91 fits into 840 9 times, leaving a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 557.69
If we subtract 819 from 840, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 8:
The number 91 fits into 210 2 times, leaving a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 557.692
Subtract 182 from 210 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 9:
91 goes into 280 3 times with a remainder of 7.
The next digit of our result is 3. 
Result so far: 557.6923
Subtract 273 from 280 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 10:
91 goes into 70 0 times with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 557.6923
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 11:
91 can be fit into 700 7 times, resulting in a remainder of 63.
The next digit of our result is 7. 
Result so far: 557.692307
Deduct 637 from 700 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 12:
630 divided by 91 is 6 with a remainder of 84.
Write down 6 as next digit of the result. 
Result so far: 557.6923076
Deduct 546 from 630 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 13:
When dividing 840 by 91, we get 9 with a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 557.69230769
If we subtract 819 from 840, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

After the division, we end up with 557.69230769 and a remainder of 2.1e-08.
