935640 ÷ 75 
The aim is to understand the frequency of 75 in 935640.

On to step 1:
9 divided by 75 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 75

Step 2:
75 goes into 93 1 times with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 75 from 93 and we're left with 18.
Grab the next digit (5) from the dividend, add it to 18, then carry on: 185 / 75

Advancing to step 3:
75 can be fit into 185 2 times, resulting in a remainder of 35.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 150 from 185 to get 35.
Include the next digit (6) from the dividend after 35, then repeat: 356 / 75

Let's proceed to step 4:
75 can be fit into 356 4 times, resulting in a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 124.0
If we take 300 away from 356, we end up with 56.
Bring next digit (4) of the dividend behind the 56 and repeat the process: 564 / 75

Step 5:
The number 75 fits into 564 7 times, leaving a remainder of 39.
Put 7 as the next digit of the answer. 
Result so far: 1247.0
Subtracting 525 from 564 leaves us with 39.
Include the next digit (0) from the dividend after 39, then repeat: 390 / 75

On to step 6:
75 can be fit into 390 5 times, resulting in a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 12475.0
If we take 375 away from 390, 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.

Going ahead to step 7:
75 goes into 150 2 times with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 12475.2
If we take 150 away from 150, 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.

Moving on to step 8:
If we divide 0 by 75, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 12475.2
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.

On to step 9:
75 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 12475.2
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.

The final outcome is 12475.2, with a leftover of 0.0.
