Let's divide 132975 by 91
The aim is to understand the frequency of 91 in 132975.

Let's proceed to step 1:
1 divided by 91 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 91

Let's proceed to step 2:
If we divide 13 by 91, we get 0 and a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Grab the next digit (2) from the dividend, add it to 13, then carry on: 132 / 91

Going ahead to step 3:
The number 91 fits into 132 1 times, leaving a remainder of 41.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 91 from 132, we get 41.
Include the next digit (9) from the dividend after 41, then repeat: 419 / 91

Step 4:
The number 91 fits into 419 4 times, leaving a remainder of 55.
Use 4 as the next digit of our solution. 
Result so far: 14.0
If we take 364 away from 419, we end up with 55.
Grab the next digit (7) from the dividend, add it to 55, then carry on: 557 / 91

On to step 5:
91 goes into 557 6 times with a remainder of 11.
Put 6 as the next digit of the answer. 
Result so far: 146.0
The remainder is 11 after subtracting 546 from 557.
Take the next digit (5) from the dividend and append it to 11, then repeat: 115 / 91

On to step 6:
115 divided by 91 is 1 with a remainder of 24.
Put 1 as the next digit of the answer. 
Result so far: 1461.0
If we subtract 91 from 115, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 7:
When dividing 240 by 91, we get 2 with a remainder of 58.
Use 2 as the next digit of our solution. 
Result so far: 1461.2
If we subtract 182 from 240, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 8:
The number 91 fits into 580 6 times, leaving a remainder of 34.
Write down 6 as next digit of the result. 
Result so far: 1461.26
Subtract 546 from 580 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 9:
The number 91 fits into 340 3 times, leaving a remainder of 67.
The next digit of our result is 3. 
Result so far: 1461.263
Subtract 273 from 340 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 10:
670 divided by 91 is 7 with a remainder of 33.
The number 7 becomes the next digit in our result. 
Result so far: 1461.2637
If we subtract 637 from 670, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 11:
91 can be fit into 330 3 times, resulting in a remainder of 57.
The number 3 becomes the next digit in our result. 
Result so far: 1461.26373
Deduct 273 from 330 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 12:
570 divided by 91 is 6 with a remainder of 24.
The next digit of our result is 6. 
Result so far: 1461.263736
If we take 546 away from 570, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 13:
91 goes into 240 2 times with a remainder of 58.
Record the quotient 2 as the next digit in the result. 
Result so far: 1461.2637362
If we subtract 182 from 240, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 14:
580 divided by 91 is 6 with a remainder of 34.
Use 6 as the next digit of our solution. 
Result so far: 1461.26373626
If we take 546 away from 580, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The quotient of the division is 1461.26373626, and the remainder is 3.4e-08.
