517593 divided by 75 
The aim is to understand the frequency of 75 in 517593.

Step 1:
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: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 75

Step 2:
75 can be fit into 51 0 times, resulting in a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Fetch the next digit (7) from the dividend, attach it to 51 and continue: 517 / 75

On to step 3:
The number 75 fits into 517 6 times, leaving a remainder of 67.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 450 away from 517, we end up with 67.
Bring next digit (5) of the dividend behind the 67 and repeat the process: 675 / 75

Advancing to step 4:
The number 75 fits into 675 9 times, leaving a remainder of 0.
The next digit of our result is 9. 
Result so far: 69.0
Deduct 675 from 675 and we're left with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 75

Moving on to step 5:
9 divided by 75 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 690.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 75

Let's proceed to step 6:
When dividing 93 by 75, we get 1 with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 6901.0
Subtract 75 from 93 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 7:
If we divide 180 by 75, we get 2 and a remainder of 30.
The number 2 becomes the next digit in our result. 
Result so far: 6901.2
The remainder is 30 after subtracting 150 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
300 divided by 75 is 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 6901.24
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.

Advancing to step 9:
When dividing 0 by 75, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 6901.24
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
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: 6901.24
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.

After the division, we end up with 6901.24 and a remainder of 0.0.
