We divide 281242 by 75
The aim is to understand the frequency of 75 in 281242.

Advancing to step 1:
When dividing 2 by 75, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 75

Moving on to step 2:
75 goes into 28 0 times with a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Include the next digit (1) from the dividend after 28, then repeat: 281 / 75

Step 3:
If we divide 281 by 75, we get 3 and a remainder of 56.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 225 from 281 leaves us with 56.
Grab the next digit (2) from the dividend, add it to 56, then carry on: 562 / 75

Moving on to step 4:
The number 75 fits into 562 7 times, leaving a remainder of 37.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
Subtract 525 from 562 to get 37.
Include the next digit (4) from the dividend after 37, then repeat: 374 / 75

Step 5:
If we divide 374 by 75, we get 4 and a remainder of 74.
The next digit of our result is 4. 
Result so far: 374.0
Subtracting 300 from 374 leaves us with 74.
Bring next digit (2) of the dividend behind the 74 and repeat the process: 742 / 75

Advancing to step 6:
If we divide 742 by 75, we get 9 and a remainder of 67.
Use 9 as the next digit of our solution. 
Result so far: 3749.0
Subtract 675 from 742 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 7:
75 goes into 670 8 times with a remainder of 70.
Put 8 as the next digit of the answer. 
Result so far: 3749.8
If we subtract 600 from 670, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 8:
700 divided by 75 is 9 with a remainder of 25.
The number 9 becomes the next digit in our result. 
Result so far: 3749.89
The remainder is 25 after subtracting 675 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 9:
When dividing 250 by 75, we get 3 with a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 3749.893
Deduct 225 from 250 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 10:
If we divide 250 by 75, we get 3 and a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 3749.8933
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 final outcome is 3749.8933, with a leftover of 0.00025.
