Let's divide 39343015 by 75
The aim is to understand the frequency of 75 in 39343015.

Going ahead to step 1:
The number 75 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 75

Going ahead to step 2:
39 divided by 75 is 0 with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Include the next digit (3) from the dividend after 39, then repeat: 393 / 75

Advancing to step 3:
When dividing 393 by 75, we get 5 with a remainder of 18.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 18 after subtracting 375 from 393.
Grab the next digit (4) from the dividend, add it to 18, then carry on: 184 / 75

On to step 4:
184 divided by 75 is 2 with a remainder of 34.
Use 2 as the next digit of our solution. 
Result so far: 52.0
If we subtract 150 from 184, we get 34.
Fetch the next digit (3) from the dividend, attach it to 34 and continue: 343 / 75

Let's proceed to step 5:
If we divide 343 by 75, we get 4 and a remainder of 43.
Put 4 as the next digit of the answer. 
Result so far: 524.0
Subtract 300 from 343 to get 43.
Take the next digit (0) from the dividend and append it to 43, then repeat: 430 / 75

Step 6:
75 can be fit into 430 5 times, resulting in a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 5245.0
If we take 375 away from 430, we end up with 55.
Include the next digit (1) from the dividend after 55, then repeat: 551 / 75

On to step 7:
551 divided by 75 is 7 with a remainder of 26.
The number 7 becomes the next digit in our result. 
Result so far: 52457.0
Deduct 525 from 551 and we're left with 26.
Grab the next digit (5) from the dividend, add it to 26, then carry on: 265 / 75

Moving on to step 8:
When dividing 265 by 75, we get 3 with a remainder of 40.
Write down 3 as next digit of the result. 
Result so far: 524573.0
Subtracting 225 from 265 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 9:
When dividing 400 by 75, we get 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 524573.5
Subtract 375 from 400 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 10:
When dividing 250 by 75, we get 3 with a remainder of 25.
The next digit of our result is 3. 
Result so far: 524573.53
The remainder is 25 after subtracting 225 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 11:
75 can be fit into 250 3 times, resulting in a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 524573.533
The remainder is 25 after subtracting 225 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Our division results in 524573.533 with a remaining 0.0025.
