We're dividing 529270 by 75 
The aim is to understand the frequency of 75 in 529270.

Advancing to step 1:
When dividing 5 by 75, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 75

On to step 2:
75 can be fit into 52 0 times, resulting in a remainder of 52.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 52 and we're left with 52.
Take the next digit (9) from the dividend and append it to 52, then repeat: 529 / 75

Step 3:
529 divided by 75 is 7 with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 4 after subtracting 525 from 529.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 75

Step 4:
75 goes into 42 0 times with a remainder of 42.
The next digit of our result is 0. 
Result so far: 70.0
Subtract 0 from 42 to get 42.
Append the next digit (7) from the dividend to 42 and continue with: 427 / 75

Step 5:
75 can be fit into 427 5 times, resulting in a remainder of 52.
Write down 5 as next digit of the result. 
Result so far: 705.0
Subtracting 375 from 427 leaves us with 52.
Include the next digit (0) from the dividend after 52, then repeat: 520 / 75

Let's proceed to step 6:
The number 75 fits into 520 6 times, leaving a remainder of 70.
Write down 6 as next digit of the result. 
Result so far: 7056.0
Subtract 450 from 520 to 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.

Step 7:
When dividing 700 by 75, we get 9 with a remainder of 25.
The number 9 becomes the next digit in our result. 
Result so far: 7056.9
If we take 675 away from 700, we end up 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.

On to step 8:
75 can be fit into 250 3 times, resulting in a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 7056.93
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.

Going ahead to step 9:
The number 75 fits into 250 3 times, leaving a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 7056.933
Subtracting 225 from 250 leaves us 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 7056.933, and the remainder is 0.0025.
