231482 ÷ 91 
The aim is to understand the frequency of 91 in 231482.

On to step 1:
The number 91 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 91

Let's proceed to step 2:
23 divided by 91 is 0 with a remainder of 23.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 23, we get 23.
Take the next digit (1) from the dividend and append it to 23, then repeat: 231 / 91

Let's proceed to step 3:
91 can be fit into 231 2 times, resulting in a remainder of 49.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 182 away from 231, we end up with 49.
Grab the next digit (4) from the dividend, add it to 49, then carry on: 494 / 91

Moving on to step 4:
If we divide 494 by 91, we get 5 and a remainder of 39.
Use 5 as the next digit of our solution. 
Result so far: 25.0
Subtracting 455 from 494 leaves us with 39.
Take the next digit (8) from the dividend and append it to 39, then repeat: 398 / 91

Moving on to step 5:
When dividing 398 by 91, we get 4 with a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 254.0
Subtracting 364 from 398 leaves us with 34.
Fetch the next digit (2) from the dividend, attach it to 34 and continue: 342 / 91

On to step 6:
91 goes into 342 3 times with a remainder of 69.
The number 3 becomes the next digit in our result. 
Result so far: 2543.0
Deduct 273 from 342 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 7:
91 can be fit into 690 7 times, resulting in a remainder of 53.
Put 7 as the next digit of the answer. 
Result so far: 2543.7
Subtract 637 from 690 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 8:
91 goes into 530 5 times with a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 2543.75
If we take 455 away from 530, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 9:
The number 91 fits into 750 8 times, leaving a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 2543.758
Subtract 728 from 750 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 10:
When dividing 220 by 91, we get 2 with a remainder of 38.
Record the quotient 2 as the next digit in the result. 
Result so far: 2543.7582
The remainder is 38 after subtracting 182 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 11:
If we divide 380 by 91, we get 4 and a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 2543.75824
The remainder is 16 after subtracting 364 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 12:
91 can be fit into 160 1 times, resulting in a remainder of 69.
Write down 1 as next digit of the result. 
Result so far: 2543.758241
The remainder is 69 after subtracting 91 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 13:
91 can be fit into 690 7 times, resulting in a remainder of 53.
Use 7 as the next digit of our solution. 
Result so far: 2543.7582417
Subtracting 637 from 690 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 14:
When dividing 530 by 91, we get 5 with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 2543.75824175
Subtract 455 from 530 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

The quotient of the division is 2543.75824175, and the remainder is 7.5e-08.
