We're dividing 410209 by 75 
The aim is to understand the frequency of 75 in 410209.

Let's proceed to step 1:
75 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 75

Going ahead to step 2:
75 can be fit into 41 0 times, resulting in a remainder of 41.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 41 to get 41.
Bring next digit (0) of the dividend behind the 41 and repeat the process: 410 / 75

Advancing to step 3:
75 can be fit into 410 5 times, resulting in a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 375 from 410 to get 35.
Include the next digit (2) from the dividend after 35, then repeat: 352 / 75

Step 4:
75 can be fit into 352 4 times, resulting in a remainder of 52.
Use 4 as the next digit of our solution. 
Result so far: 54.0
The remainder is 52 after subtracting 300 from 352.
Append the next digit (0) from the dividend to 52 and continue with: 520 / 75

Step 5:
When dividing 520 by 75, we get 6 with a remainder of 70.
The number 6 becomes the next digit in our result. 
Result so far: 546.0
The remainder is 70 after subtracting 450 from 520.
Append the next digit (9) from the dividend to 70 and continue with: 709 / 75

Step 6:
If we divide 709 by 75, we get 9 and a remainder of 34.
The number 9 becomes the next digit in our result. 
Result so far: 5469.0
The remainder is 34 after subtracting 675 from 709.
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 7:
75 can be fit into 340 4 times, resulting in a remainder of 40.
The next digit of our result is 4. 
Result so far: 5469.4
If we subtract 300 from 340, 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.

Advancing to step 8:
The number 75 fits into 400 5 times, leaving a remainder of 25.
The next digit of our result is 5. 
Result so far: 5469.45
The remainder is 25 after subtracting 375 from 400.
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 9:
75 can be fit into 250 3 times, resulting in a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 5469.453
If we subtract 225 from 250, 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.

On to step 10:
The number 75 fits into 250 3 times, leaving a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 5469.4533
The remainder is 25 after subtracting 225 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The quotient of the division is 5469.4533, and the remainder is 0.00025.
