453740 divided by 42 
Our goal is to divide 453740 by 42.

Going ahead to step 1:
42 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 42

On to step 2:
42 goes into 45 1 times with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 42 from 45 leaves us with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 42

On to step 3:
42 can be fit into 33 0 times, resulting in a remainder of 33.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 33 after subtracting 0 from 33.
Bring next digit (7) of the dividend behind the 33 and repeat the process: 337 / 42

Advancing to step 4:
42 can be fit into 337 8 times, resulting in a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 108.0
If we take 336 away from 337, we end up with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 42

Step 5:
When dividing 14 by 42, we get 0 with a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 1080.0
The remainder is 14 after subtracting 0 from 14.
Append the next digit (0) from the dividend to 14 and continue with: 140 / 42

Step 6:
When dividing 140 by 42, we get 3 with a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 10803.0
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.

Step 7:
When dividing 140 by 42, we get 3 with a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 10803.3
Subtract 126 from 140 to 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.

Step 8:
If we divide 140 by 42, we get 3 and a remainder of 14.
The next digit of our result is 3. 
Result so far: 10803.33
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 result is 10803.33 with a remainder of 0.014.
