We divide 825591 by 75
The aim is to understand the frequency of 75 in 825591.

Advancing to step 1:
The number 75 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 75

Advancing to step 2:
82 divided by 75 is 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 7 after subtracting 75 from 82.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 75

Step 3:
When dividing 75 by 75, we get 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Deduct 75 from 75 and we're left with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 75

Advancing to step 4:
The number 75 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 110.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 75

Step 5:
59 divided by 75 is 0 with a remainder of 59.
Use 0 as the next digit of our solution. 
Result so far: 1100.0
The remainder is 59 after subtracting 0 from 59.
Append the next digit (1) from the dividend to 59 and continue with: 591 / 75

Advancing to step 6:
When dividing 591 by 75, we get 7 with a remainder of 66.
The next digit of our result is 7. 
Result so far: 11007.0
Subtracting 525 from 591 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 7:
When dividing 660 by 75, we get 8 with a remainder of 60.
Write down 8 as next digit of the result. 
Result so far: 11007.8
If we subtract 600 from 660, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 8:
75 goes into 600 8 times with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 11007.88
If we subtract 600 from 600, we 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.

The final result is 11007.88 with a remainder of 0.0.
