342441 divided by 75 
The aim is to understand the frequency of 75 in 342441.

Step 1:
When dividing 3 by 75, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 75

On to step 2:
75 can be fit into 34 0 times, resulting in a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 34 leaves us with 34.
Append the next digit (2) from the dividend to 34 and continue with: 342 / 75

On to step 3:
75 goes into 342 4 times with a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 300 from 342 leaves us with 42.
Fetch the next digit (4) from the dividend, attach it to 42 and continue: 424 / 75

Going ahead to step 4:
When dividing 424 by 75, we get 5 with a remainder of 49.
Use 5 as the next digit of our solution. 
Result so far: 45.0
Subtract 375 from 424 to get 49.
Take the next digit (4) from the dividend and append it to 49, then repeat: 494 / 75

Moving on to step 5:
75 can be fit into 494 6 times, resulting in a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 456.0
Subtracting 450 from 494 leaves us with 44.
Grab the next digit (1) from the dividend, add it to 44, then carry on: 441 / 75

Going ahead to step 6:
When dividing 441 by 75, we get 5 with a remainder of 66.
Write down 5 as next digit of the result. 
Result so far: 4565.0
Subtracting 375 from 441 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 7:
75 can be fit into 660 8 times, resulting in a remainder of 60.
Use 8 as the next digit of our solution. 
Result so far: 4565.8
The remainder is 60 after subtracting 600 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 8:
600 divided by 75 is 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 4565.88
Deduct 600 from 600 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.

The final result is 4565.88 with a remainder of 0.0.
