We look at the division of 64314431 by 752 
The aim is to understand the frequency of 752 in 64314431.

On to step 1:
752 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 752

Moving on to step 2:
64 divided by 752 is 0 with a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Take the next digit (3) from the dividend and append it to 64, then repeat: 643 / 752

Advancing to step 3:
752 can be fit into 643 0 times, resulting in a remainder of 643.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 643 after subtracting 0 from 643.
Append the next digit (1) from the dividend to 643 and continue with: 6431 / 752

Going ahead to step 4:
6431 divided by 752 is 8 with a remainder of 415.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 6016 from 6431, we get 415.
Grab the next digit (4) from the dividend, add it to 415, then carry on: 4154 / 752

Moving on to step 5:
The number 752 fits into 4154 5 times, leaving a remainder of 394.
Put 5 as the next digit of the answer. 
Result so far: 85.0
If we take 3760 away from 4154, we end up with 394.
Fetch the next digit (4) from the dividend, attach it to 394 and continue: 3944 / 752

Let's proceed to step 6:
If we divide 3944 by 752, we get 5 and a remainder of 184.
Write down 5 as next digit of the result. 
Result so far: 855.0
If we take 3760 away from 3944, we end up with 184.
Bring next digit (3) of the dividend behind the 184 and repeat the process: 1843 / 752

Step 7:
752 can be fit into 1843 2 times, resulting in a remainder of 339.
Record the quotient 2 as the next digit in the result. 
Result so far: 8552.0
Subtracting 1504 from 1843 leaves us with 339.
Fetch the next digit (1) from the dividend, attach it to 339 and continue: 3391 / 752

Going ahead to step 8:
752 can be fit into 3391 4 times, resulting in a remainder of 383.
Use 4 as the next digit of our solution. 
Result so far: 85524.0
Deduct 3008 from 3391 and we're left with 383.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3830, and continue the process.

Advancing to step 9:
3830 divided by 752 is 5 with a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 85524.5
Subtract 3760 from 3830 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 10:
The number 752 fits into 700 0 times, leaving a remainder of 700.
Write down 0 as next digit of the result. 
Result so far: 85524.5
Subtracting 0 from 700 leaves us with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Advancing to step 11:
If we divide 7000 by 752, we get 9 and a remainder of 232.
Write down 9 as next digit of the result. 
Result so far: 85524.509
Deduct 6768 from 7000 and we're left with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Going ahead to step 12:
The number 752 fits into 2320 3 times, leaving a remainder of 64.
Use 3 as the next digit of our solution. 
Result so far: 85524.5093
If we subtract 2256 from 2320, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 13:
752 can be fit into 640 0 times, resulting in a remainder of 640.
Write down 0 as next digit of the result. 
Result so far: 85524.5093
Subtracting 0 from 640 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Advancing to step 14:
752 can be fit into 6400 8 times, resulting in a remainder of 384.
The next digit of our result is 8. 
Result so far: 85524.509308
If we subtract 6016 from 6400, we get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

On to step 15:
If we divide 3840 by 752, we get 5 and a remainder of 80.
The next digit of our result is 5. 
Result so far: 85524.5093085
If we take 3760 away from 3840, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 16:
The number 752 fits into 800 1 times, leaving a remainder of 48.
Record the quotient 1 as the next digit in the result. 
Result so far: 85524.50930851
If we take 752 away from 800, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final result is 85524.50930851 with a remainder of 4.8e-08.
