We're dividing 891496 by 75 
The aim is to understand the frequency of 75 in 891496.

Going ahead to step 1:
If we divide 8 by 75, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 75

Advancing 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
If we take 75 away from 89, we end up with 14.
Grab the next digit (1) from the dividend, add it to 14, then carry on: 141 / 75

Step 3:
75 can be fit into 141 1 times, resulting in a remainder of 66.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we take 75 away from 141, we end up with 66.
Bring next digit (4) of the dividend behind the 66 and repeat the process: 664 / 75

Step 4:
664 divided by 75 is 8 with a remainder of 64.
The next digit of our result is 8. 
Result so far: 118.0
If we subtract 600 from 664, we get 64.
Bring next digit (9) of the dividend behind the 64 and repeat the process: 649 / 75

Moving on to step 5:
649 divided by 75 is 8 with a remainder of 49.
The next digit of our result is 8. 
Result so far: 1188.0
Subtracting 600 from 649 leaves us with 49.
Grab the next digit (6) from the dividend, add it to 49, then carry on: 496 / 75

Moving on to step 6:
When dividing 496 by 75, we get 6 with a remainder of 46.
Write down 6 as next digit of the result. 
Result so far: 11886.0
Subtract 450 from 496 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 7:
When dividing 460 by 75, we get 6 with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 11886.6
The remainder is 10 after subtracting 450 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
75 can be fit into 100 1 times, resulting in a remainder of 25.
Write down 1 as next digit of the result. 
Result so far: 11886.61
The remainder is 25 after subtracting 75 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 9:
If we divide 250 by 75, we get 3 and a remainder of 25.
Write down 3 as next digit of the result. 
Result so far: 11886.613
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.

Step 10:
The number 75 fits into 250 3 times, leaving a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 11886.6133
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 11886.6133 with a remainder of 0.00025.
