647597 divided by 75 
The aim is to understand the frequency of 75 in 647597.

Step 1:
75 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 75

Step 2:
64 divided by 75 is 0 with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Append the next digit (7) from the dividend to 64 and continue with: 647 / 75

Step 3:
When dividing 647 by 75, we get 8 with a remainder of 47.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 47 after subtracting 600 from 647.
Bring next digit (5) of the dividend behind the 47 and repeat the process: 475 / 75

Going ahead to step 4:
75 can be fit into 475 6 times, resulting in a remainder of 25.
Put 6 as the next digit of the answer. 
Result so far: 86.0
If we take 450 away from 475, we end up with 25.
Grab the next digit (9) from the dividend, add it to 25, then carry on: 259 / 75

On to step 5:
When dividing 259 by 75, we get 3 with a remainder of 34.
The next digit of our result is 3. 
Result so far: 863.0
Subtracting 225 from 259 leaves us with 34.
Take the next digit (7) from the dividend and append it to 34, then repeat: 347 / 75

Moving on to step 6:
347 divided by 75 is 4 with a remainder of 47.
The next digit of our result is 4. 
Result so far: 8634.0
The remainder is 47 after subtracting 300 from 347.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 7:
75 goes into 470 6 times with a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 8634.6
If we take 450 away from 470, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
200 divided by 75 is 2 with a remainder of 50.
Put 2 as the next digit of the answer. 
Result so far: 8634.62
Subtracting 150 from 200 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 9:
If we divide 500 by 75, we get 6 and a remainder of 50.
The next digit of our result is 6. 
Result so far: 8634.626
The remainder is 50 after subtracting 450 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 10:
The number 75 fits into 500 6 times, leaving a remainder of 50.
The next digit of our result is 6. 
Result so far: 8634.6266
If we take 450 away from 500, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final outcome is 8634.6266, with a leftover of 0.0005.
