Let's divide 537795 by 91
The aim is to understand the frequency of 91 in 537795.

Advancing to step 1:
The number 91 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 91

Step 2:
53 divided by 91 is 0 with a remainder of 53.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 53 and we're left with 53.
Grab the next digit (7) from the dividend, add it to 53, then carry on: 537 / 91

Let's proceed to step 3:
91 can be fit into 537 5 times, resulting in a remainder of 82.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 455 from 537, we get 82.
Fetch the next digit (7) from the dividend, attach it to 82 and continue: 827 / 91

Let's proceed to step 4:
The number 91 fits into 827 9 times, leaving a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 59.0
If we subtract 819 from 827, we get 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 91

Moving on to step 5:
When dividing 89 by 91, we get 0 with a remainder of 89.
Record the quotient 0 as the next digit in the result. 
Result so far: 590.0
If we subtract 0 from 89, we get 89.
Include the next digit (5) from the dividend after 89, then repeat: 895 / 91

Step 6:
The number 91 fits into 895 9 times, leaving a remainder of 76.
Record the quotient 9 as the next digit in the result. 
Result so far: 5909.0
Subtracting 819 from 895 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 7:
When dividing 760 by 91, we get 8 with a remainder of 32.
The next digit of our result is 8. 
Result so far: 5909.8
The remainder is 32 after subtracting 728 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 8:
91 can be fit into 320 3 times, resulting in a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 5909.83
Deduct 273 from 320 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 9:
When dividing 470 by 91, we get 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 5909.835
If we subtract 455 from 470, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 10:
91 goes into 150 1 times with a remainder of 59.
The number 1 becomes the next digit in our result. 
Result so far: 5909.8351
Subtract 91 from 150 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 11:
When dividing 590 by 91, we get 6 with a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 5909.83516
Deduct 546 from 590 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 12:
91 can be fit into 440 4 times, resulting in a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 5909.835164
If we take 364 away from 440, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 13:
91 goes into 760 8 times with a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 5909.8351648
Deduct 728 from 760 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 14:
If we divide 320 by 91, we get 3 and a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 5909.83516483
Subtract 273 from 320 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

The final result is 5909.83516483 with a remainder of 4.7e-08.
