We look at the division of 353513 by 41 
The aim is to understand the frequency of 41 in 353513.

Step 1:
41 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 41

Step 2:
When dividing 35 by 41, we get 0 with a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 35 and we're left with 35.
Take the next digit (3) from the dividend and append it to 35, then repeat: 353 / 41

Step 3:
41 can be fit into 353 8 times, resulting in a remainder of 25.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 25 after subtracting 328 from 353.
Grab the next digit (5) from the dividend, add it to 25, then carry on: 255 / 41

Going ahead to step 4:
When dividing 255 by 41, we get 6 with a remainder of 9.
The next digit of our result is 6. 
Result so far: 86.0
Subtract 246 from 255 to get 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 41

Let's proceed to step 5:
41 goes into 91 2 times with a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 862.0
Deduct 82 from 91 and we're left with 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 41

Moving on to step 6:
The number 41 fits into 93 2 times, leaving a remainder of 11.
The next digit of our result is 2. 
Result so far: 8622.0
The remainder is 11 after subtracting 82 from 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 7:
When dividing 110 by 41, we get 2 with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 8622.2
Subtract 82 from 110 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 8:
If we divide 280 by 41, we get 6 and a remainder of 34.
Put 6 as the next digit of the answer. 
Result so far: 8622.26
Subtracting 246 from 280 leaves us 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.

Advancing to step 9:
When dividing 340 by 41, we get 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 8622.268
The remainder is 12 after subtracting 328 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 10:
The number 41 fits into 120 2 times, leaving a remainder of 38.
Record the quotient 2 as the next digit in the result. 
Result so far: 8622.2682
Deduct 82 from 120 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 11:
If we divide 380 by 41, we get 9 and a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 8622.26829
Subtracting 369 from 380 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 12:
41 can be fit into 110 2 times, resulting in a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 8622.268292
Deduct 82 from 110 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 13:
280 divided by 41 is 6 with a remainder of 34.
Record the quotient 6 as the next digit in the result. 
Result so far: 8622.2682926
If we subtract 246 from 280, we 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.

Moving on to step 14:
If we divide 340 by 41, we get 8 and a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 8622.26829268
The remainder is 12 after subtracting 328 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 8622.26829268, with a leftover of 1.2e-08.
