We look at the division of 255394 by 42 
Our goal is to divide 255394 by 42.

Step 1:
2 divided by 42 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 42

Moving on to step 2:
If we divide 25 by 42, we get 0 and a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Include the next digit (5) from the dividend after 25, then repeat: 255 / 42

Going ahead to step 3:
42 can be fit into 255 6 times, resulting in a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 252 from 255 and we're left with 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 42

On to step 4:
The number 42 fits into 33 0 times, leaving a remainder of 33.
The number 0 becomes the next digit in our result. 
Result so far: 60.0
If we take 0 away from 33, we end up with 33.
Append the next digit (9) from the dividend to 33 and continue with: 339 / 42

On to step 5:
42 can be fit into 339 8 times, resulting in a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 608.0
If we subtract 336 from 339, we get 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 42

Moving on to step 6:
34 divided by 42 is 0 with a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 6080.0
If we take 0 away from 34, we end up 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.

Going ahead to step 7:
If we divide 340 by 42, we get 8 and a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 6080.8
Subtract 336 from 340 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
42 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 6080.8
If we subtract 0 from 40, we get 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:
42 can be fit into 400 9 times, resulting in a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 6080.809
Subtracting 378 from 400 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 10:
220 divided by 42 is 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 6080.8095
If we take 210 away from 220, 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.

Going ahead to step 11:
When dividing 100 by 42, we get 2 with a remainder of 16.
The next digit of our result is 2. 
Result so far: 6080.80952
Deduct 84 from 100 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 12:
160 divided by 42 is 3 with a remainder of 34.
Write down 3 as next digit of the result. 
Result so far: 6080.809523
Subtracting 126 from 160 leaves us 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.

Moving on to step 13:
340 divided by 42 is 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 6080.8095238
If we subtract 336 from 340, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 14:
When dividing 40 by 42, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 6080.8095238
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 6080.8095238 and a remainder of 4e-08.
