We look at the division of 755281 by 42 
We want to divide 755281 by 42.

Step 1:
42 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 42

Moving on to step 2:
If we divide 75 by 42, we get 1 and a remainder of 33.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 42 from 75 leaves us with 33.
Bring next digit (5) of the dividend behind the 33 and repeat the process: 335 / 42

Moving on to step 3:
When dividing 335 by 42, we get 7 with a remainder of 41.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we subtract 294 from 335, we get 41.
Append the next digit (2) from the dividend to 41 and continue with: 412 / 42

Moving on to step 4:
When dividing 412 by 42, we get 9 with a remainder of 34.
Put 9 as the next digit of the answer. 
Result so far: 179.0
Subtract 378 from 412 to get 34.
Fetch the next digit (8) from the dividend, attach it to 34 and continue: 348 / 42

Moving on to step 5:
348 divided by 42 is 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 1798.0
The remainder is 12 after subtracting 336 from 348.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 42

Moving on to step 6:
When dividing 121 by 42, we get 2 with a remainder of 37.
Put 2 as the next digit of the answer. 
Result so far: 17982.0
If we take 84 away from 121, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 7:
If we divide 370 by 42, we get 8 and a remainder of 34.
Put 8 as the next digit of the answer. 
Result so far: 17982.8
Deduct 336 from 370 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 8:
340 divided by 42 is 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 17982.88
Subtracting 336 from 340 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 17982.88 with a remaining 0.004.
