We're dividing 426830 by 75 
The aim is to understand the frequency of 75 in 426830.

Moving on to step 1:
4 divided by 75 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 75

Moving on to step 2:
When dividing 42 by 75, we get 0 with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 42 after subtracting 0 from 42.
Append the next digit (6) from the dividend to 42 and continue with: 426 / 75

Step 3:
If we divide 426 by 75, we get 5 and a remainder of 51.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 375 from 426, we get 51.
Append the next digit (8) from the dividend to 51 and continue with: 518 / 75

Let's proceed to step 4:
518 divided by 75 is 6 with a remainder of 68.
Write down 6 as next digit of the result. 
Result so far: 56.0
If we subtract 450 from 518, we get 68.
Take the next digit (3) from the dividend and append it to 68, then repeat: 683 / 75

Moving on to step 5:
If we divide 683 by 75, we get 9 and a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 569.0
If we take 675 away from 683, we end up with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 75

Going ahead to step 6:
75 goes into 80 1 times with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 5691.0
Subtracting 75 from 80 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
75 can be fit into 50 0 times, resulting in a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 5691.0
Subtracting 0 from 50 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.

Step 8:
75 goes into 500 6 times with a remainder of 50.
Use 6 as the next digit of our solution. 
Result so far: 5691.06
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.

Step 9:
75 goes into 500 6 times with a remainder of 50.
Put 6 as the next digit of the answer. 
Result so far: 5691.066
Subtract 450 from 500 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The quotient of the division is 5691.066, and the remainder is 0.005.
