We're dividing 502357 by 91 
The aim is to understand the frequency of 91 in 502357.

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

Step 2:
If we divide 50 by 91, we get 0 and a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 50, we get 50.
Bring next digit (2) of the dividend behind the 50 and repeat the process: 502 / 91

Let's proceed to step 3:
502 divided by 91 is 5 with a remainder of 47.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 455 from 502 to get 47.
Bring next digit (3) of the dividend behind the 47 and repeat the process: 473 / 91

Advancing to step 4:
If we divide 473 by 91, we get 5 and a remainder of 18.
Record the quotient 5 as the next digit in the result. 
Result so far: 55.0
If we subtract 455 from 473, we get 18.
Grab the next digit (5) from the dividend, add it to 18, then carry on: 185 / 91

Going ahead to step 5:
91 can be fit into 185 2 times, resulting in a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 552.0
If we subtract 182 from 185, we get 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 91

Let's proceed to step 6:
91 can be fit into 37 0 times, resulting in a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 5520.0
Subtracting 0 from 37 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.

On to step 7:
91 goes into 370 4 times with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 5520.4
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 8:
When dividing 60 by 91, we get 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 5520.4
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 9:
The number 91 fits into 600 6 times, leaving a remainder of 54.
Record the quotient 6 as the next digit in the result. 
Result so far: 5520.406
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.

Let's proceed to step 10:
540 divided by 91 is 5 with a remainder of 85.
The next digit of our result is 5. 
Result so far: 5520.4065
Subtracting 455 from 540 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 11:
If we divide 850 by 91, we get 9 and a remainder of 31.
Write down 9 as next digit of the result. 
Result so far: 5520.40659
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 12:
310 divided by 91 is 3 with a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 5520.406593
If we subtract 273 from 310, we 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.

Advancing to step 13:
370 divided by 91 is 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 5520.4065934
If we take 364 away from 370, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 14:
The number 91 fits into 60 0 times, leaving a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 5520.4065934
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

In conclusion, the division gives 5520.4065934 with a balance of 6e-08.
