256571 divided by 42 
Let's see how many times 42 fits into 256571.

Step 1:
42 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 42

On to step 2:
25 divided by 42 is 0 with a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Append the next digit (6) from the dividend to 25 and continue with: 256 / 42

Step 3:
If we divide 256 by 42, we get 6 and a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 252 away from 256, we end up with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 42

On to step 4:
42 can be fit into 45 1 times, resulting in a remainder of 3.
The next digit of our result is 1. 
Result so far: 61.0
Subtracting 42 from 45 leaves us with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 42

Moving on to step 5:
42 goes into 37 0 times with a remainder of 37.
Use 0 as the next digit of our solution. 
Result so far: 610.0
Subtract 0 from 37 to get 37.
Append the next digit (1) from the dividend to 37 and continue with: 371 / 42

On to step 6:
42 goes into 371 8 times with a remainder of 35.
The number 8 becomes the next digit in our result. 
Result so far: 6108.0
The remainder is 35 after subtracting 336 from 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 7:
When dividing 350 by 42, we get 8 with a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 6108.8
If we take 336 away from 350, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 8:
42 goes into 140 3 times with a remainder of 14.
The next digit of our result is 3. 
Result so far: 6108.83
The remainder is 14 after subtracting 126 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 9:
42 can be fit into 140 3 times, resulting in a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 6108.833
Subtracting 126 from 140 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final outcome is 6108.833, with a leftover of 0.0014.
