834456 ÷ 42 
Our goal is to divide 834456 by 42.

Let's proceed to step 1:
When dividing 8 by 42, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 42

Going ahead to step 2:
83 divided by 42 is 1 with a remainder of 41.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 42 from 83 leaves us with 41.
Grab the next digit (4) from the dividend, add it to 41, then carry on: 414 / 42

Moving on to step 3:
42 can be fit into 414 9 times, resulting in a remainder of 36.
Use 9 as the next digit of our solution. 
Result so far: 19.0
If we take 378 away from 414, we end up with 36.
Include the next digit (4) from the dividend after 36, then repeat: 364 / 42

Let's proceed to step 4:
42 goes into 364 8 times with a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 198.0
If we subtract 336 from 364, we get 28.
Include the next digit (5) from the dividend after 28, then repeat: 285 / 42

Moving on to step 5:
42 can be fit into 285 6 times, resulting in a remainder of 33.
Put 6 as the next digit of the answer. 
Result so far: 1986.0
Subtract 252 from 285 to get 33.
Include the next digit (6) from the dividend after 33, then repeat: 336 / 42

Let's proceed to step 6:
The number 42 fits into 336 8 times, leaving a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 19868.0
If we subtract 336 from 336, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
0 divided by 42 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 19868.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
If we divide 0 by 42, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 19868.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 19868.0 with a remaining 0.0.
