450771 divided by 18 
Let's see how many times 18 fits into 450771.

Step 1:
4 divided by 18 is 0 with 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 / 18

Step 2:
The number 18 fits into 45 2 times, leaving a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 9 after subtracting 36 from 45.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 18

Step 3:
If we divide 90 by 18, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
If we subtract 90 from 90, we get 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 18

Step 4:
18 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 250.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 18

Advancing to step 5:
When dividing 77 by 18, we get 4 with a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 2504.0
Subtracting 72 from 77 leaves us with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 18

Let's proceed to step 6:
The number 18 fits into 51 2 times, leaving a remainder of 15.
Use 2 as the next digit of our solution. 
Result so far: 25042.0
If we take 36 away from 51, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 7:
If we divide 150 by 18, we get 8 and a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 25042.8
If we subtract 144 from 150, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
If we divide 60 by 18, we get 3 and a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 25042.83
The remainder is 6 after subtracting 54 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
When dividing 60 by 18, we get 3 with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 25042.833
If we subtract 54 from 60, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Our division results in 25042.833 with a remaining 0.0006.
