We look at the division of 898414 by 75 
The aim is to understand the frequency of 75 in 898414.

Step 1:
When dividing 8 by 75, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 75

Going ahead to step 2:
75 can be fit into 89 1 times, resulting in a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 75 from 89 and we're left with 14.
Include the next digit (8) from the dividend after 14, then repeat: 148 / 75

On to step 3:
When dividing 148 by 75, we get 1 with a remainder of 73.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we subtract 75 from 148, we get 73.
Take the next digit (4) from the dividend and append it to 73, then repeat: 734 / 75

Advancing to step 4:
75 goes into 734 9 times with a remainder of 59.
Put 9 as the next digit of the answer. 
Result so far: 119.0
Subtracting 675 from 734 leaves us with 59.
Append the next digit (1) from the dividend to 59 and continue with: 591 / 75

Let's proceed to step 5:
If we divide 591 by 75, we get 7 and a remainder of 66.
Record the quotient 7 as the next digit in the result. 
Result so far: 1197.0
Subtract 525 from 591 to get 66.
Fetch the next digit (4) from the dividend, attach it to 66 and continue: 664 / 75

Advancing to step 6:
When dividing 664 by 75, we get 8 with a remainder of 64.
Record the quotient 8 as the next digit in the result. 
Result so far: 11978.0
Deduct 600 from 664 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 7:
75 goes into 640 8 times with a remainder of 40.
The next digit of our result is 8. 
Result so far: 11978.8
If we take 600 away from 640, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 8:
If we divide 400 by 75, we get 5 and a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 11978.85
The remainder is 25 after subtracting 375 from 400.
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:
250 divided by 75 is 3 with a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 11978.853
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.

Advancing to step 10:
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: 11978.8533
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.

The final outcome is 11978.8533, with a leftover of 0.00025.
