We look at the division of 345360 by 41 
The aim is to understand the frequency of 41 in 345360.

On to step 1:
If we divide 3 by 41, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 41

Step 2:
If we divide 34 by 41, we get 0 and a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 34 after subtracting 0 from 34.
Append the next digit (5) from the dividend to 34 and continue with: 345 / 41

Moving on to step 3:
41 goes into 345 8 times with a remainder of 17.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 328 from 345 leaves us with 17.
Grab the next digit (3) from the dividend, add it to 17, then carry on: 173 / 41

Going ahead to step 4:
If we divide 173 by 41, we get 4 and a remainder of 9.
Record the quotient 4 as the next digit in the result. 
Result so far: 84.0
If we take 164 away from 173, we end up with 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 41

Advancing to step 5:
41 goes into 96 2 times with a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 842.0
If we subtract 82 from 96, we get 14.
Fetch the next digit (0) from the dividend, attach it to 14 and continue: 140 / 41

Going ahead to step 6:
If we divide 140 by 41, we get 3 and a remainder of 17.
The next digit of our result is 3. 
Result so far: 8423.0
If we subtract 123 from 140, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
When dividing 170 by 41, we get 4 with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 8423.4
Subtract 164 from 170 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
60 divided by 41 is 1 with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 8423.41
The remainder is 19 after subtracting 41 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 9:
41 goes into 190 4 times with a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 8423.414
If we take 164 away from 190, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 10:
The number 41 fits into 260 6 times, leaving a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 8423.4146
If we subtract 246 from 260, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 11:
41 goes into 140 3 times with a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 8423.41463
If we subtract 123 from 140, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 12:
When dividing 170 by 41, we get 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 8423.414634
If we subtract 164 from 170, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 13:
41 goes into 60 1 times with a remainder of 19.
The next digit of our result is 1. 
Result so far: 8423.4146341
Subtracting 41 from 60 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 14:
190 divided by 41 is 4 with a remainder of 26.
The next digit of our result is 4. 
Result so far: 8423.41463414
If we subtract 164 from 190, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The quotient of the division is 8423.41463414, and the remainder is 2.6e-08.
