133591 ÷ 41 
The aim is to understand the frequency of 41 in 133591.

On to step 1:
41 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 41

Step 2:
When dividing 13 by 41, we get 0 with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Take the next digit (3) from the dividend and append it to 13, then repeat: 133 / 41

Moving on to step 3:
If we divide 133 by 41, we get 3 and a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 123 from 133, we get 10.
Grab the next digit (5) from the dividend, add it to 10, then carry on: 105 / 41

Moving on to step 4:
41 can be fit into 105 2 times, resulting in a remainder of 23.
The next digit of our result is 2. 
Result so far: 32.0
Subtract 82 from 105 to get 23.
Include the next digit (9) from the dividend after 23, then repeat: 239 / 41

Step 5:
41 goes into 239 5 times with a remainder of 34.
The next digit of our result is 5. 
Result so far: 325.0
If we subtract 205 from 239, we get 34.
Take the next digit (1) from the dividend and append it to 34, then repeat: 341 / 41

On to step 6:
If we divide 341 by 41, we get 8 and a remainder of 13.
Use 8 as the next digit of our solution. 
Result so far: 3258.0
Subtract 328 from 341 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 7:
When dividing 130 by 41, we get 3 with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 3258.3
If we subtract 123 from 130, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 8:
The number 41 fits into 70 1 times, leaving a remainder of 29.
The next digit of our result is 1. 
Result so far: 3258.31
Subtracting 41 from 70 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 9:
41 can be fit into 290 7 times, resulting in a remainder of 3.
The next digit of our result is 7. 
Result so far: 3258.317
Subtract 287 from 290 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 10:
30 divided by 41 is 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 3258.317
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 11:
When dividing 300 by 41, we get 7 with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 3258.31707
Subtracting 287 from 300 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 12:
The number 41 fits into 130 3 times, leaving a remainder of 7.
The next digit of our result is 3. 
Result so far: 3258.317073
If we take 123 away from 130, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 13:
When dividing 70 by 41, we get 1 with a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 3258.3170731
If we subtract 41 from 70, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 14:
If we divide 290 by 41, we get 7 and a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 3258.31707317
If we subtract 287 from 290, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final outcome is 3258.31707317, with a leftover of 3e-09.
