We're dividing 124354 by 91 
The aim is to understand the frequency of 91 in 124354.

Moving on to step 1:
The number 91 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 91

Let's proceed to step 2:
91 can be fit into 12 0 times, resulting in a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Include the next digit (4) from the dividend after 12, then repeat: 124 / 91

On to step 3:
If we divide 124 by 91, we get 1 and a remainder of 33.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 91 away from 124, we end up with 33.
Grab the next digit (3) from the dividend, add it to 33, then carry on: 333 / 91

Step 4:
The number 91 fits into 333 3 times, leaving a remainder of 60.
The next digit of our result is 3. 
Result so far: 13.0
If we take 273 away from 333, we end up with 60.
Bring next digit (5) of the dividend behind the 60 and repeat the process: 605 / 91

Step 5:
When dividing 605 by 91, we get 6 with a remainder of 59.
Record the quotient 6 as the next digit in the result. 
Result so far: 136.0
Deduct 546 from 605 and we're left with 59.
Include the next digit (4) from the dividend after 59, then repeat: 594 / 91

Step 6:
91 goes into 594 6 times with a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 1366.0
If we subtract 546 from 594, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 7:
480 divided by 91 is 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 1366.5
Subtract 455 from 480 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 8:
91 goes into 250 2 times with a remainder of 68.
The next digit of our result is 2. 
Result so far: 1366.52
If we subtract 182 from 250, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 9:
The number 91 fits into 680 7 times, leaving a remainder of 43.
The number 7 becomes the next digit in our result. 
Result so far: 1366.527
Subtracting 637 from 680 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 10:
91 can be fit into 430 4 times, resulting in a remainder of 66.
Record the quotient 4 as the next digit in the result. 
Result so far: 1366.5274
If we subtract 364 from 430, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 11:
660 divided by 91 is 7 with a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 1366.52747
If we take 637 away from 660, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 12:
The number 91 fits into 230 2 times, leaving a remainder of 48.
The next digit of our result is 2. 
Result so far: 1366.527472
The remainder is 48 after subtracting 182 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 13:
If we divide 480 by 91, we get 5 and a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 1366.5274725
If we take 455 away from 480, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 14:
If we divide 250 by 91, we get 2 and a remainder of 68.
Write down 2 as next digit of the result. 
Result so far: 1366.52747252
Deduct 182 from 250 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The quotient of the division is 1366.52747252, and the remainder is 6.8e-08.
