417811 divided by 42 
We want to divide 417811 by 42.

Step 1:
42 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 42

Step 2:
42 can be fit into 41 0 times, resulting in a remainder of 41.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 41 leaves us with 41.
Grab the next digit (7) from the dividend, add it to 41, then carry on: 417 / 42

Step 3:
If we divide 417 by 42, we get 9 and a remainder of 39.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 378 from 417, we get 39.
Include the next digit (8) from the dividend after 39, then repeat: 398 / 42

Let's proceed to step 4:
398 divided by 42 is 9 with a remainder of 20.
The number 9 becomes the next digit in our result. 
Result so far: 99.0
Deduct 378 from 398 and we're left with 20.
Take the next digit (1) from the dividend and append it to 20, then repeat: 201 / 42

Moving on to step 5:
42 goes into 201 4 times with a remainder of 33.
The next digit of our result is 4. 
Result so far: 994.0
Subtract 168 from 201 to get 33.
Append the next digit (1) from the dividend to 33 and continue with: 331 / 42

On to step 6:
The number 42 fits into 331 7 times, leaving a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 9947.0
If we subtract 294 from 331, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 7:
The number 42 fits into 370 8 times, leaving a remainder of 34.
Write down 8 as next digit of the result. 
Result so far: 9947.8
Subtracting 336 from 370 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 8:
The number 42 fits into 340 8 times, leaving a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 9947.88
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.

The final result is 9947.88 with a remainder of 0.004.
