We divide 649830 by 75
The aim is to understand the frequency of 75 in 649830.

Moving on to step 1:
6 divided by 75 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 75

Step 2:
75 can be fit into 64 0 times, resulting in a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Fetch the next digit (9) from the dividend, attach it to 64 and continue: 649 / 75

Let's proceed to step 3:
649 divided by 75 is 8 with a remainder of 49.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 600 away from 649, we end up with 49.
Take the next digit (8) from the dividend and append it to 49, then repeat: 498 / 75

On to step 4:
75 goes into 498 6 times with a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 86.0
Subtracting 450 from 498 leaves us with 48.
Bring next digit (3) of the dividend behind the 48 and repeat the process: 483 / 75

Let's proceed to step 5:
The number 75 fits into 483 6 times, leaving a remainder of 33.
Write down 6 as next digit of the result. 
Result so far: 866.0
Deduct 450 from 483 and we're left with 33.
Grab the next digit (0) from the dividend, add it to 33, then carry on: 330 / 75

Let's proceed to step 6:
The number 75 fits into 330 4 times, leaving a remainder of 30.
Record the quotient 4 as the next digit in the result. 
Result so far: 8664.0
If we take 300 away from 330, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 7:
When dividing 300 by 75, we get 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 8664.4
The remainder is 0 after subtracting 300 from 300.
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 8:
When dividing 0 by 75, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 8664.4
Subtracting 0 from 0 leaves us with 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 9:
When dividing 0 by 75, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 8664.4
Subtract 0 from 0 to 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.

The quotient of the division is 8664.4, and the remainder is 0.0.
