304491 divided by 75 
The aim is to understand the frequency of 75 in 304491.

Step 1:
The number 75 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 75

On to step 2:
30 divided by 75 is 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Bring next digit (4) of the dividend behind the 30 and repeat the process: 304 / 75

Moving on to step 3:
75 can be fit into 304 4 times, resulting in a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 300 from 304 to get 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 75

Moving on to step 4:
The number 75 fits into 44 0 times, leaving a remainder of 44.
Write down 0 as next digit of the result. 
Result so far: 40.0
If we subtract 0 from 44, we get 44.
Include the next digit (9) from the dividend after 44, then repeat: 449 / 75

Moving on to step 5:
The number 75 fits into 449 5 times, leaving a remainder of 74.
The number 5 becomes the next digit in our result. 
Result so far: 405.0
If we take 375 away from 449, we end up with 74.
Append the next digit (1) from the dividend to 74 and continue with: 741 / 75

Advancing to step 6:
75 can be fit into 741 9 times, resulting in a remainder of 66.
The number 9 becomes the next digit in our result. 
Result so far: 4059.0
Deduct 675 from 741 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 7:
When dividing 660 by 75, we get 8 with a remainder of 60.
Record the quotient 8 as the next digit in the result. 
Result so far: 4059.8
The remainder is 60 after subtracting 600 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 8:
600 divided by 75 is 8 with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 4059.88
Subtract 600 from 600 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 4059.88 with a remainder of 0.0.
