We look at the division of 202429 by 75 
The aim is to understand the frequency of 75 in 202429.

On 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
Subtract 0 from 2 to get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 75

Step 2:
75 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Grab the next digit (2) from the dividend, add it to 20, then carry on: 202 / 75

Moving on to step 3:
75 can be fit into 202 2 times, resulting in a remainder of 52.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 52 after subtracting 150 from 202.
Append the next digit (4) from the dividend to 52 and continue with: 524 / 75

On to step 4:
524 divided by 75 is 6 with a remainder of 74.
The next digit of our result is 6. 
Result so far: 26.0
The remainder is 74 after subtracting 450 from 524.
Fetch the next digit (2) from the dividend, attach it to 74 and continue: 742 / 75

Advancing to step 5:
75 goes into 742 9 times with a remainder of 67.
Put 9 as the next digit of the answer. 
Result so far: 269.0
If we subtract 675 from 742, we get 67.
Include the next digit (9) from the dividend after 67, then repeat: 679 / 75

Step 6:
75 goes into 679 9 times with a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 2699.0
Subtract 675 from 679 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
The number 75 fits into 40 0 times, leaving a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 2699.0
If we subtract 0 from 40, 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.

Moving on to step 8:
When dividing 400 by 75, we get 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 2699.05
Subtract 375 from 400 to 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.

Advancing to step 9:
When dividing 250 by 75, we get 3 with a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 2699.053
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.

Let's proceed to step 10:
If we divide 250 by 75, we get 3 and a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 2699.0533
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.

The quotient of the division is 2699.0533, and the remainder is 0.00025.
