439815 ÷ 75 
The aim is to understand the frequency of 75 in 439815.

Moving on to step 1:
4 divided by 75 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 75

Going ahead to step 2:
75 goes into 43 0 times with a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Include the next digit (9) from the dividend after 43, then repeat: 439 / 75

Let's proceed to step 3:
The number 75 fits into 439 5 times, leaving a remainder of 64.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 375 from 439 to get 64.
Grab the next digit (8) from the dividend, add it to 64, then carry on: 648 / 75

Going ahead to step 4:
If we divide 648 by 75, we get 8 and a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 58.0
Subtracting 600 from 648 leaves us with 48.
Fetch the next digit (1) from the dividend, attach it to 48 and continue: 481 / 75

Let's proceed to step 5:
481 divided by 75 is 6 with a remainder of 31.
Put 6 as the next digit of the answer. 
Result so far: 586.0
Deduct 450 from 481 and we're left with 31.
Take the next digit (5) from the dividend and append it to 31, then repeat: 315 / 75

Going ahead to step 6:
When dividing 315 by 75, we get 4 with a remainder of 15.
The next digit of our result is 4. 
Result so far: 5864.0
If we take 300 away from 315, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
75 goes into 150 2 times with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 5864.2
Subtracting 150 from 150 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.

Going ahead to step 8:
75 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 5864.2
Deduct 0 from 0 and we're left 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.

Going ahead to step 9:
0 divided by 75 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 5864.2
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.

After the division, we end up with 5864.2 and a remainder of 0.0.
