We're dividing 659403 by 75 
The aim is to understand the frequency of 75 in 659403.

Going ahead to step 1:
6 divided by 75 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 75

Going ahead to step 2:
75 goes into 65 0 times with a remainder of 65.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 65, we end up with 65.
Fetch the next digit (9) from the dividend, attach it to 65 and continue: 659 / 75

Moving on to step 3:
The number 75 fits into 659 8 times, leaving a remainder of 59.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 600 from 659 and we're left with 59.
Fetch the next digit (4) from the dividend, attach it to 59 and continue: 594 / 75

Let's proceed to step 4:
75 can be fit into 594 7 times, resulting in a remainder of 69.
Write down 7 as next digit of the result. 
Result so far: 87.0
Deduct 525 from 594 and we're left with 69.
Bring next digit (0) of the dividend behind the 69 and repeat the process: 690 / 75

Step 5:
If we divide 690 by 75, we get 9 and a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 879.0
The remainder is 15 after subtracting 675 from 690.
Include the next digit (3) from the dividend after 15, then repeat: 153 / 75

Step 6:
If we divide 153 by 75, we get 2 and a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 8792.0
Deduct 150 from 153 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
75 can be fit into 30 0 times, resulting in a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 8792.0
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
When dividing 300 by 75, we get 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 8792.04
If we subtract 300 from 300, 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.

Let's proceed to step 9:
If we divide 0 by 75, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 8792.04
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
If we divide 0 by 75, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8792.04
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.

In conclusion, the division gives 8792.04 with a balance of 0.0.
