Let's divide 30012 by 75
The aim is to understand the frequency of 75 in 30012.

Step 1:
75 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 75

Let's proceed to step 2:
75 goes into 30 0 times with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Bring next digit (0) of the dividend behind the 30 and repeat the process: 300 / 75

Advancing to step 3:
The number 75 fits into 300 4 times, leaving a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 0 after subtracting 300 from 300.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 75

Going ahead to step 4:
If we divide 1 by 75, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 75

Going ahead to step 5:
When dividing 12 by 75, we get 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 400.0
If we subtract 0 from 12, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 6:
The number 75 fits into 120 1 times, leaving a remainder of 45.
Put 1 as the next digit of the answer. 
Result so far: 400.1
Subtract 75 from 120 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 7:
The number 75 fits into 450 6 times, leaving a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 400.16
If we subtract 450 from 450, we 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.

Going ahead to step 8:
0 divided by 75 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 400.16
Subtract 0 from 0 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.

Let's proceed to step 9:
75 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 400.16
Subtracting 0 from 0 leaves us with 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 quotient of the division is 400.16, and the remainder is 0.0.
