We look at the division of 898237 by 75 
The aim is to understand the frequency of 75 in 898237.

Moving on to step 1:
If we divide 8 by 75, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 75

Let's proceed to step 2:
When dividing 89 by 75, we get 1 with a remainder of 14.
The next digit of our result is 1. 
Result so far: 1.0
If we take 75 away from 89, we end up with 14.
Grab the next digit (8) from the dividend, add it to 14, then carry on: 148 / 75

On to step 3:
If we divide 148 by 75, we get 1 and a remainder of 73.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we take 75 away from 148, we end up with 73.
Grab the next digit (2) from the dividend, add it to 73, then carry on: 732 / 75

Let's proceed to step 4:
The number 75 fits into 732 9 times, leaving a remainder of 57.
The next digit of our result is 9. 
Result so far: 119.0
If we subtract 675 from 732, we get 57.
Include the next digit (3) from the dividend after 57, then repeat: 573 / 75

Going ahead to step 5:
If we divide 573 by 75, we get 7 and a remainder of 48.
Use 7 as the next digit of our solution. 
Result so far: 1197.0
If we subtract 525 from 573, we get 48.
Take the next digit (7) from the dividend and append it to 48, then repeat: 487 / 75

Advancing to step 6:
75 goes into 487 6 times with a remainder of 37.
Record the quotient 6 as the next digit in the result. 
Result so far: 11976.0
If we take 450 away from 487, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 7:
The number 75 fits into 370 4 times, leaving a remainder of 70.
Write down 4 as next digit of the result. 
Result so far: 11976.4
The remainder is 70 after subtracting 300 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 8:
If we divide 700 by 75, we get 9 and a remainder of 25.
Write down 9 as next digit of the result. 
Result so far: 11976.49
Subtract 675 from 700 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.

On to step 9:
The number 75 fits into 250 3 times, leaving a remainder of 25.
The next digit of our result is 3. 
Result so far: 11976.493
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.

Moving on to step 10:
75 goes into 250 3 times with a remainder of 25.
Put 3 as the next digit of the answer. 
Result so far: 11976.4933
Subtract 225 from 250 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.

The final result is 11976.4933 with a remainder of 0.00025.
