648452 divided by 41 
The aim is to understand the frequency of 41 in 648452.

Step 1:
41 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 41

Going ahead to step 2:
The number 41 fits into 64 1 times, leaving a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 41 from 64 leaves us with 23.
Include the next digit (8) from the dividend after 23, then repeat: 238 / 41

On to step 3:
41 can be fit into 238 5 times, resulting in a remainder of 33.
The next digit of our result is 5. 
Result so far: 15.0
If we subtract 205 from 238, we get 33.
Append the next digit (4) from the dividend to 33 and continue with: 334 / 41

Let's proceed to step 4:
The number 41 fits into 334 8 times, leaving a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 158.0
Deduct 328 from 334 and we're left with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 41

Let's proceed to step 5:
65 divided by 41 is 1 with a remainder of 24.
The next digit of our result is 1. 
Result so far: 1581.0
Subtract 41 from 65 to get 24.
Grab the next digit (2) from the dividend, add it to 24, then carry on: 242 / 41

Moving on to step 6:
242 divided by 41 is 5 with a remainder of 37.
The number 5 becomes the next digit in our result. 
Result so far: 15815.0
The remainder is 37 after subtracting 205 from 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 7:
The number 41 fits into 370 9 times, leaving a remainder of 1.
The next digit of our result is 9. 
Result so far: 15815.9
If we subtract 369 from 370, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 8:
When dividing 10 by 41, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 15815.9
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
The number 41 fits into 100 2 times, leaving a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 15815.902
If we take 82 away from 100, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 10:
The number 41 fits into 180 4 times, leaving a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 15815.9024
The remainder is 16 after subtracting 164 from 180.
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 11:
If we divide 160 by 41, we get 3 and a remainder of 37.
Write down 3 as next digit of the result. 
Result so far: 15815.90243
If we subtract 123 from 160, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 12:
370 divided by 41 is 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 15815.902439
If we take 369 away from 370, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 13:
41 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 15815.902439
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 14:
100 divided by 41 is 2 with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 15815.90243902
If we take 82 away from 100, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final result is 15815.90243902 with a remainder of 1.8e-08.
