We're dividing 740725 by 75 
The aim is to understand the frequency of 75 in 740725.

Going ahead to step 1:
When dividing 7 by 75, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 75

Step 2:
When dividing 74 by 75, we get 0 with a remainder of 74.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 74 after subtracting 0 from 74.
Bring next digit (0) of the dividend behind the 74 and repeat the process: 740 / 75

Let's proceed to step 3:
740 divided by 75 is 9 with a remainder of 65.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 675 from 740, we get 65.
Fetch the next digit (7) from the dividend, attach it to 65 and continue: 657 / 75

Moving on to step 4:
657 divided by 75 is 8 with a remainder of 57.
Use 8 as the next digit of our solution. 
Result so far: 98.0
If we take 600 away from 657, we end up with 57.
Take the next digit (2) from the dividend and append it to 57, then repeat: 572 / 75

On to step 5:
572 divided by 75 is 7 with a remainder of 47.
Record the quotient 7 as the next digit in the result. 
Result so far: 987.0
If we subtract 525 from 572, we get 47.
Fetch the next digit (5) from the dividend, attach it to 47 and continue: 475 / 75

Advancing to step 6:
75 can be fit into 475 6 times, resulting in a remainder of 25.
Record the quotient 6 as the next digit in the result. 
Result so far: 9876.0
If we take 450 away from 475, 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.

Step 7:
250 divided by 75 is 3 with a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 9876.3
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.

On to step 8:
When dividing 250 by 75, we get 3 with a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 9876.33
If we take 225 away from 250, 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.

The final result is 9876.33 with a remainder of 0.025.
