Let's divide 646322 by 75
The aim is to understand the frequency of 75 in 646322.

Advancing to step 1:
If we divide 6 by 75, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 75

Going ahead to step 2:
75 goes into 64 0 times with a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Include the next digit (6) from the dividend after 64, then repeat: 646 / 75

Let's proceed to step 3:
The number 75 fits into 646 8 times, leaving a remainder of 46.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 600 from 646 to get 46.
Append the next digit (3) from the dividend to 46 and continue with: 463 / 75

Moving on to step 4:
75 can be fit into 463 6 times, resulting in a remainder of 13.
Put 6 as the next digit of the answer. 
Result so far: 86.0
The remainder is 13 after subtracting 450 from 463.
Append the next digit (2) from the dividend to 13 and continue with: 132 / 75

Let's proceed to step 5:
When dividing 132 by 75, we get 1 with a remainder of 57.
Put 1 as the next digit of the answer. 
Result so far: 861.0
Subtract 75 from 132 to get 57.
Append the next digit (2) from the dividend to 57 and continue with: 572 / 75

On to step 6:
If we divide 572 by 75, we get 7 and a remainder of 47.
The number 7 becomes the next digit in our result. 
Result so far: 8617.0
The remainder is 47 after subtracting 525 from 572.
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:
470 divided by 75 is 6 with a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 8617.6
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.

Step 8:
The number 75 fits into 200 2 times, leaving a remainder of 50.
Record the quotient 2 as the next digit in the result. 
Result so far: 8617.62
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.

Going ahead to step 9:
The number 75 fits into 500 6 times, leaving a remainder of 50.
The next digit of our result is 6. 
Result so far: 8617.626
Deduct 450 from 500 and we're left 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.

Going ahead to step 10:
When dividing 500 by 75, we get 6 with a remainder of 50.
The number 6 becomes the next digit in our result. 
Result so far: 8617.6266
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.

After the division, we end up with 8617.6266 and a remainder of 0.0005.
