We look at the division of 452802 by 18 
Our goal is to divide 452802 by 18.

Step 1:
The number 18 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 18

Let's proceed to step 2:
18 goes into 45 2 times with a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 36 from 45 leaves us with 9.
Bring next digit (2) of the dividend behind the 9 and repeat the process: 92 / 18

Moving on to step 3:
92 divided by 18 is 5 with a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 25.0
Subtract 90 from 92 to get 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 18

Advancing to step 4:
18 goes into 28 1 times with a remainder of 10.
The next digit of our result is 1. 
Result so far: 251.0
Subtract 18 from 28 to get 10.
Include the next digit (0) from the dividend after 10, then repeat: 100 / 18

Step 5:
18 goes into 100 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 2515.0
Subtract 90 from 100 to get 10.
Take the next digit (2) from the dividend and append it to 10, then repeat: 102 / 18

On to step 6:
18 can be fit into 102 5 times, resulting in a remainder of 12.
Write down 5 as next digit of the result. 
Result so far: 25155.0
Deduct 90 from 102 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 7:
120 divided by 18 is 6 with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 25155.6
Subtracting 108 from 120 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 8:
18 can be fit into 120 6 times, resulting in a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 25155.66
The remainder is 12 after subtracting 108 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 25155.66, with a leftover of 0.012.
