We look at the division of 728388 by 41 
The aim is to understand the frequency of 41 in 728388.

On to step 1:
If we divide 7 by 41, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 41

Advancing to step 2:
If we divide 72 by 41, we get 1 and a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 41 from 72 and we're left with 31.
Include the next digit (8) from the dividend after 31, then repeat: 318 / 41

On to step 3:
If we divide 318 by 41, we get 7 and a remainder of 31.
Write down 7 as next digit of the result. 
Result so far: 17.0
Deduct 287 from 318 and we're left with 31.
Bring next digit (3) of the dividend behind the 31 and repeat the process: 313 / 41

On to step 4:
If we divide 313 by 41, we get 7 and a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 177.0
Subtracting 287 from 313 leaves us with 26.
Grab the next digit (8) from the dividend, add it to 26, then carry on: 268 / 41

Going ahead to step 5:
If we divide 268 by 41, we get 6 and a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 1776.0
Deduct 246 from 268 and we're left with 22.
Fetch the next digit (8) from the dividend, attach it to 22 and continue: 228 / 41

On to step 6:
If we divide 228 by 41, we get 5 and a remainder of 23.
The next digit of our result is 5. 
Result so far: 17765.0
Subtracting 205 from 228 leaves us 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.

Advancing to step 7:
41 goes into 230 5 times with a remainder of 25.
The next digit of our result is 5. 
Result so far: 17765.5
If we subtract 205 from 230, we 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.

Moving on to step 8:
The number 41 fits into 250 6 times, leaving a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 17765.56
The remainder is 4 after subtracting 246 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
41 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 17765.56
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 10:
The number 41 fits into 400 9 times, leaving a remainder of 31.
Record the quotient 9 as the next digit in the result. 
Result so far: 17765.5609
If we take 369 away from 400, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 11:
41 goes into 310 7 times with a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 17765.56097
Deduct 287 from 310 and we're left 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.

Step 12:
41 goes into 230 5 times with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 17765.560975
Subtract 205 from 230 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 13:
41 goes into 250 6 times with a remainder of 4.
The next digit of our result is 6. 
Result so far: 17765.5609756
Deduct 246 from 250 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 14:
40 divided by 41 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 17765.5609756
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 17765.5609756 with a remainder of 4e-08.
