We look at the division of 425446 by 75 
The aim is to understand the frequency of 75 in 425446.

On to step 1:
The number 75 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 75

Let's proceed to step 2:
When dividing 42 by 75, we get 0 with a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Bring next digit (5) of the dividend behind the 42 and repeat the process: 425 / 75

Let's proceed to step 3:
When dividing 425 by 75, we get 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 375 from 425 leaves us with 50.
Grab the next digit (4) from the dividend, add it to 50, then carry on: 504 / 75

On to step 4:
75 can be fit into 504 6 times, resulting in a remainder of 54.
Put 6 as the next digit of the answer. 
Result so far: 56.0
Subtract 450 from 504 to get 54.
Append the next digit (4) from the dividend to 54 and continue with: 544 / 75

Going ahead to step 5:
The number 75 fits into 544 7 times, leaving a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 567.0
Subtract 525 from 544 to get 19.
Fetch the next digit (6) from the dividend, attach it to 19 and continue: 196 / 75

Let's proceed to step 6:
196 divided by 75 is 2 with a remainder of 46.
The next digit of our result is 2. 
Result so far: 5672.0
The remainder is 46 after subtracting 150 from 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 7:
75 can be fit into 460 6 times, resulting in a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 5672.6
Subtracting 450 from 460 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
100 divided by 75 is 1 with a remainder of 25.
The next digit of our result is 1. 
Result so far: 5672.61
Subtracting 75 from 100 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.

Moving on to step 9:
75 goes into 250 3 times with a remainder of 25.
The next digit of our result is 3. 
Result so far: 5672.613
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.

Moving on to step 10:
75 goes into 250 3 times with a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 5672.6133
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.

Our division results in 5672.6133 with a remaining 0.00025.
