We're dividing 816046 by 42 
Our goal is to divide 816046 by 42.

Going ahead to step 1:
42 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 42

Let's proceed to step 2:
When dividing 81 by 42, we get 1 with a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 42 from 81 leaves us with 39.
Append the next digit (6) from the dividend to 39 and continue with: 396 / 42

Advancing to step 3:
When dividing 396 by 42, we get 9 with a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Deduct 378 from 396 and we're left with 18.
Append the next digit (0) from the dividend to 18 and continue with: 180 / 42

On to step 4:
The number 42 fits into 180 4 times, leaving a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 194.0
If we take 168 away from 180, we end up with 12.
Append the next digit (4) from the dividend to 12 and continue with: 124 / 42

Going ahead to step 5:
42 can be fit into 124 2 times, resulting in a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 1942.0
The remainder is 40 after subtracting 84 from 124.
Append the next digit (6) from the dividend to 40 and continue with: 406 / 42

Going ahead to step 6:
If we divide 406 by 42, we get 9 and a remainder of 28.
The next digit of our result is 9. 
Result so far: 19429.0
Deduct 378 from 406 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 7:
42 goes into 280 6 times with a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 19429.6
Deduct 252 from 280 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 8:
42 goes into 280 6 times with a remainder of 28.
The next digit of our result is 6. 
Result so far: 19429.66
Subtracting 252 from 280 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

After the division, we end up with 19429.66 and a remainder of 0.028.
