We're dividing 64396799 by 750 
The aim is to understand the frequency of 750 in 64396799.

Going ahead to step 1:
6 divided by 750 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 750

On to step 2:
When dividing 64 by 750, we get 0 with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Take the next digit (3) from the dividend and append it to 64, then repeat: 643 / 750

Going ahead to step 3:
When dividing 643 by 750, we get 0 with a remainder of 643.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 643 after subtracting 0 from 643.
Bring next digit (9) of the dividend behind the 643 and repeat the process: 6439 / 750

On to step 4:
The number 750 fits into 6439 8 times, leaving a remainder of 439.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 439 after subtracting 6000 from 6439.
Bring next digit (6) of the dividend behind the 439 and repeat the process: 4396 / 750

Going ahead to step 5:
When dividing 4396 by 750, we get 5 with a remainder of 646.
Use 5 as the next digit of our solution. 
Result so far: 85.0
Subtracting 3750 from 4396 leaves us with 646.
Grab the next digit (7) from the dividend, add it to 646, then carry on: 6467 / 750

Advancing to step 6:
When dividing 6467 by 750, we get 8 with a remainder of 467.
Put 8 as the next digit of the answer. 
Result so far: 858.0
Deduct 6000 from 6467 and we're left with 467.
Fetch the next digit (9) from the dividend, attach it to 467 and continue: 4679 / 750

Going ahead to step 7:
750 goes into 4679 6 times with a remainder of 179.
The number 6 becomes the next digit in our result. 
Result so far: 8586.0
Deduct 4500 from 4679 and we're left with 179.
Include the next digit (9) from the dividend after 179, then repeat: 1799 / 750

Going ahead to step 8:
750 goes into 1799 2 times with a remainder of 299.
Put 2 as the next digit of the answer. 
Result so far: 85862.0
The remainder is 299 after subtracting 1500 from 1799.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Step 9:
750 can be fit into 2990 3 times, resulting in a remainder of 740.
The number 3 becomes the next digit in our result. 
Result so far: 85862.3
If we subtract 2250 from 2990, we get 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Moving on to step 10:
7400 divided by 750 is 9 with a remainder of 650.
The number 9 becomes the next digit in our result. 
Result so far: 85862.39
If we subtract 6750 from 7400, we get 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Step 11:
When dividing 6500 by 750, we get 8 with a remainder of 500.
Use 8 as the next digit of our solution. 
Result so far: 85862.398
If we subtract 6000 from 6500, we get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

On to step 12:
5000 divided by 750 is 6 with a remainder of 500.
Write down 6 as next digit of the result. 
Result so far: 85862.3986
Subtract 4500 from 5000 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Going ahead to step 13:
5000 divided by 750 is 6 with a remainder of 500.
Record the quotient 6 as the next digit in the result. 
Result so far: 85862.39866
Subtract 4500 from 5000 to get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Our division results in 85862.39866 with a remaining 0.0005.
