423926 divided by 75 
The aim is to understand the frequency of 75 in 423926.

Moving on to step 1:
4 divided by 75 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 75

Let's proceed to step 2:
If we divide 42 by 75, we get 0 and a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Grab the next digit (3) from the dividend, add it to 42, then carry on: 423 / 75

Moving on to step 3:
423 divided by 75 is 5 with a remainder of 48.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 375 from 423, we get 48.
Bring next digit (9) of the dividend behind the 48 and repeat the process: 489 / 75

Going ahead to step 4:
When dividing 489 by 75, we get 6 with a remainder of 39.
Use 6 as the next digit of our solution. 
Result so far: 56.0
Deduct 450 from 489 and we're left with 39.
Grab the next digit (2) from the dividend, add it to 39, then carry on: 392 / 75

Going ahead to step 5:
75 goes into 392 5 times with a remainder of 17.
Record the quotient 5 as the next digit in the result. 
Result so far: 565.0
Subtracting 375 from 392 leaves us with 17.
Take the next digit (6) from the dividend and append it to 17, then repeat: 176 / 75

Let's proceed to step 6:
75 can be fit into 176 2 times, resulting in a remainder of 26.
Record the quotient 2 as the next digit in the result. 
Result so far: 5652.0
If we subtract 150 from 176, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 7:
If we divide 260 by 75, we get 3 and a remainder of 35.
Record the quotient 3 as the next digit in the result. 
Result so far: 5652.3
If we subtract 225 from 260, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 8:
The number 75 fits into 350 4 times, leaving a remainder of 50.
The number 4 becomes the next digit in our result. 
Result so far: 5652.34
The remainder is 50 after subtracting 300 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 9:
If we divide 500 by 75, we get 6 and a remainder of 50.
Write down 6 as next digit of the result. 
Result so far: 5652.346
If we subtract 450 from 500, we 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.

On to step 10:
500 divided by 75 is 6 with a remainder of 50.
Write down 6 as next digit of the result. 
Result so far: 5652.3466
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.

Our division results in 5652.3466 with a remaining 0.0005.
