We look at the division of 814995 by 75 
The aim is to understand the frequency of 75 in 814995.

Let's proceed to step 1:
8 divided by 75 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 75

Let's proceed to step 2:
The number 75 fits into 81 1 times, leaving a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 75 from 81, we get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 75

Advancing to step 3:
75 can be fit into 64 0 times, resulting in a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 64, we end up with 64.
Include the next digit (9) from the dividend after 64, then repeat: 649 / 75

Moving on to step 4:
The number 75 fits into 649 8 times, leaving a remainder of 49.
Use 8 as the next digit of our solution. 
Result so far: 108.0
Subtract 600 from 649 to get 49.
Grab the next digit (9) from the dividend, add it to 49, then carry on: 499 / 75

Moving on to step 5:
499 divided by 75 is 6 with a remainder of 49.
Record the quotient 6 as the next digit in the result. 
Result so far: 1086.0
Deduct 450 from 499 and we're left with 49.
Bring next digit (5) of the dividend behind the 49 and repeat the process: 495 / 75

Step 6:
The number 75 fits into 495 6 times, leaving a remainder of 45.
The number 6 becomes the next digit in our result. 
Result so far: 10866.0
If we take 450 away from 495, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 7:
75 goes into 450 6 times with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 10866.6
The remainder is 0 after subtracting 450 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
If we divide 0 by 75, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10866.6
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
75 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10866.6
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 10866.6 and a remainder of 0.0.
