We're dividing 4255 by 30 
We want to divide 4255 by 30.

Going ahead to step 1:
30 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 30

Moving on to step 2:
42 divided by 30 is 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 12 after subtracting 30 from 42.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 30

Going ahead to step 3:
30 goes into 125 4 times with a remainder of 5.
The next digit of our result is 4. 
Result so far: 14.0
If we take 120 away from 125, we end up with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 30

Step 4:
55 divided by 30 is 1 with a remainder of 25.
The number 1 becomes the next digit in our result. 
Result so far: 141.0
Deduct 30 from 55 and we're left with 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 5:
250 divided by 30 is 8 with a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 141.8
The remainder is 10 after subtracting 240 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 6:
30 can be fit into 100 3 times, resulting in a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 141.83
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
The number 30 fits into 100 3 times, leaving a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 141.833
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The quotient of the division is 141.833, and the remainder is 0.001.
