We're dividing 343571 by 75 
The aim is to understand the frequency of 75 in 343571.

Going ahead to step 1:
75 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 75

Advancing to step 2:
When dividing 34 by 75, we get 0 with a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 34, we get 34.
Fetch the next digit (3) from the dividend, attach it to 34 and continue: 343 / 75

Going ahead to step 3:
75 goes into 343 4 times with a remainder of 43.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 300 from 343, we get 43.
Include the next digit (5) from the dividend after 43, then repeat: 435 / 75

Moving on to step 4:
75 goes into 435 5 times with a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 45.0
The remainder is 60 after subtracting 375 from 435.
Take the next digit (7) from the dividend and append it to 60, then repeat: 607 / 75

Moving on to step 5:
When dividing 607 by 75, we get 8 with a remainder of 7.
Use 8 as the next digit of our solution. 
Result so far: 458.0
Deduct 600 from 607 and we're left with 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 75

Step 6:
75 can be fit into 71 0 times, resulting in a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 4580.0
Subtracting 0 from 71 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 7:
When dividing 710 by 75, we get 9 with a remainder of 35.
Put 9 as the next digit of the answer. 
Result so far: 4580.9
If we take 675 away from 710, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 8:
350 divided by 75 is 4 with a remainder of 50.
Use 4 as the next digit of our solution. 
Result so far: 4580.94
If we take 300 away from 350, we end up 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.

Advancing to step 9:
75 goes into 500 6 times with a remainder of 50.
Write down 6 as next digit of the result. 
Result so far: 4580.946
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.

Advancing to step 10:
75 can be fit into 500 6 times, resulting in a remainder of 50.
Put 6 as the next digit of the answer. 
Result so far: 4580.9466
The remainder is 50 after subtracting 450 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

In conclusion, the division gives 4580.9466 with a balance of 0.0005.
