We're dividing 939843 by 75 
The aim is to understand the frequency of 75 in 939843.

Advancing to step 1:
When dividing 9 by 75, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 75

Moving on to step 2:
75 goes into 93 1 times with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 75 from 93 to get 18.
Include the next digit (9) from the dividend after 18, then repeat: 189 / 75

Let's proceed to step 3:
If we divide 189 by 75, we get 2 and a remainder of 39.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 39 after subtracting 150 from 189.
Grab the next digit (8) from the dividend, add it to 39, then carry on: 398 / 75

Let's proceed to step 4:
398 divided by 75 is 5 with a remainder of 23.
The next digit of our result is 5. 
Result so far: 125.0
If we subtract 375 from 398, we get 23.
Bring next digit (4) of the dividend behind the 23 and repeat the process: 234 / 75

Step 5:
When dividing 234 by 75, we get 3 with a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 1253.0
If we take 225 away from 234, we end up with 9.
Bring next digit (3) of the dividend behind the 9 and repeat the process: 93 / 75

Advancing to step 6:
If we divide 93 by 75, we get 1 and a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 12531.0
If we subtract 75 from 93, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
If we divide 180 by 75, we get 2 and a remainder of 30.
The number 2 becomes the next digit in our result. 
Result so far: 12531.2
If we take 150 away from 180, 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.

Going ahead to step 8:
The number 75 fits into 300 4 times, leaving a remainder of 0.
The next digit of our result is 4. 
Result so far: 12531.24
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.

Moving on to step 9:
0 divided by 75 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12531.24
If we subtract 0 from 0, we 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.

On to step 10:
75 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 12531.24
If we take 0 away from 0, we end up 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.

The quotient of the division is 12531.24, and the remainder is 0.0.
