We're dividing 955506 by 91 
The aim is to understand the frequency of 91 in 955506.

On to step 1:
If we divide 9 by 91, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 91

Advancing to step 2:
When dividing 95 by 91, we get 1 with a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 91 from 95, we get 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 91

Step 3:
45 divided by 91 is 0 with a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 45, we end up with 45.
Take the next digit (5) from the dividend and append it to 45, then repeat: 455 / 91

On to step 4:
455 divided by 91 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 105.0
If we take 455 away from 455, we end up with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 91

On to step 5:
91 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1050.0
Subtract 0 from 0 to get 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 91

Going ahead to step 6:
When dividing 6 by 91, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 10500.0
The remainder is 6 after subtracting 0 from 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
91 can be fit into 60 0 times, resulting in a remainder of 60.
The next digit of our result is 0. 
Result so far: 10500.0
Subtract 0 from 60 to 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.

Step 8:
600 divided by 91 is 6 with a remainder of 54.
The next digit of our result is 6. 
Result so far: 10500.06
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 9:
When dividing 540 by 91, we get 5 with a remainder of 85.
The number 5 becomes the next digit in our result. 
Result so far: 10500.065
The remainder is 85 after subtracting 455 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 10:
91 goes into 850 9 times with a remainder of 31.
The number 9 becomes the next digit in our result. 
Result so far: 10500.0659
Subtract 819 from 850 to 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.

Moving on to step 11:
When dividing 310 by 91, we get 3 with a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 10500.06593
The remainder is 37 after subtracting 273 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 12:
The number 91 fits into 370 4 times, leaving a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 10500.065934
Subtract 364 from 370 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 13:
If we divide 60 by 91, we get 0 and a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 10500.065934
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.

Going ahead to step 14:
91 can be fit into 600 6 times, resulting in a remainder of 54.
The next digit of our result is 6. 
Result so far: 10500.06593406
If we subtract 546 from 600, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

After the division, we end up with 10500.06593406 and a remainder of 5.4e-08.
