We divide 843311 by 42
We're looking to find how many times 42 goes into 843311.

Moving on 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
Subtract 0 from 8 to get 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 42

On to step 2:
42 can be fit into 84 2 times, resulting in a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 84 from 84 leaves us with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 42

Moving on to step 3:
3 divided by 42 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 20.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 42

Let's proceed to step 4:
When dividing 33 by 42, we get 0 with a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 200.0
Subtracting 0 from 33 leaves us with 33.
Append the next digit (1) from the dividend to 33 and continue with: 331 / 42

Step 5:
42 goes into 331 7 times with a remainder of 37.
The number 7 becomes the next digit in our result. 
Result so far: 2007.0
If we take 294 away from 331, we end up with 37.
Take the next digit (1) from the dividend and append it to 37, then repeat: 371 / 42

On to step 6:
If we divide 371 by 42, we get 8 and a remainder of 35.
Put 8 as the next digit of the answer. 
Result so far: 20078.0
Subtracting 336 from 371 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 7:
350 divided by 42 is 8 with a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 20078.8
If we subtract 336 from 350, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 8:
The number 42 fits into 140 3 times, leaving a remainder of 14.
Use 3 as the next digit of our solution. 
Result so far: 20078.83
If we subtract 126 from 140, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 9:
The number 42 fits into 140 3 times, leaving a remainder of 14.
Use 3 as the next digit of our solution. 
Result so far: 20078.833
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 20078.833, with a leftover of 0.0014.
