We're dividing 455812 by 42 
Our goal is to divide 455812 by 42.

Step 1:
42 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 42

Advancing to step 2:
42 can be fit into 45 1 times, resulting in a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 42 from 45, we get 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 42

Advancing to step 3:
When dividing 35 by 42, we get 0 with a remainder of 35.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 35, we get 35.
Grab the next digit (8) from the dividend, add it to 35, then carry on: 358 / 42

On to step 4:
42 goes into 358 8 times with a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 108.0
If we subtract 336 from 358, we get 22.
Take the next digit (1) from the dividend and append it to 22, then repeat: 221 / 42

Let's proceed to step 5:
The number 42 fits into 221 5 times, leaving a remainder of 11.
Write down 5 as next digit of the result. 
Result so far: 1085.0
Subtract 210 from 221 to get 11.
Fetch the next digit (2) from the dividend, attach it to 11 and continue: 112 / 42

Moving on to step 6:
112 divided by 42 is 2 with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 10852.0
If we take 84 away from 112, we end up 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.

Let's proceed to step 7:
280 divided by 42 is 6 with a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 10852.6
Subtract 252 from 280 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 8:
The number 42 fits into 280 6 times, leaving a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 10852.66
If we subtract 252 from 280, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The quotient of the division is 10852.66, and the remainder is 0.028.
