Let's divide 573369 by 75
The aim is to understand the frequency of 75 in 573369.

Step 1:
The number 75 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 75

Advancing to step 2:
If we divide 57 by 75, we get 0 and a remainder of 57.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 57 leaves us with 57.
Bring next digit (3) of the dividend behind the 57 and repeat the process: 573 / 75

Step 3:
If we divide 573 by 75, we get 7 and a remainder of 48.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 525 from 573 leaves us with 48.
Bring next digit (3) of the dividend behind the 48 and repeat the process: 483 / 75

Let's proceed to step 4:
75 can be fit into 483 6 times, resulting in a remainder of 33.
Put 6 as the next digit of the answer. 
Result so far: 76.0
Deduct 450 from 483 and we're left with 33.
Fetch the next digit (6) from the dividend, attach it to 33 and continue: 336 / 75

Let's proceed to step 5:
75 goes into 336 4 times with a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 764.0
Deduct 300 from 336 and we're left with 36.
Append the next digit (9) from the dividend to 36 and continue with: 369 / 75

Step 6:
The number 75 fits into 369 4 times, leaving a remainder of 69.
The number 4 becomes the next digit in our result. 
Result so far: 7644.0
If we subtract 300 from 369, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 7:
75 can be fit into 690 9 times, resulting in a remainder of 15.
Record the quotient 9 as the next digit in the result. 
Result so far: 7644.9
Deduct 675 from 690 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 8:
75 can be fit into 150 2 times, resulting in a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 7644.92
Deduct 150 from 150 and we're left 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.

Going ahead to step 9:
The number 75 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 7644.92
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:
75 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 7644.92
If we subtract 0 from 0, 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 outcome is 7644.92, with a leftover of 0.0.
