450717 divided by 18 
Let's see how many times 18 fits into 450717.

Let's proceed to step 1:
The number 18 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 18

Moving on to step 2:
If we divide 45 by 18, we get 2 and a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 36 from 45 and we're left with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 18

Advancing to step 3:
90 divided by 18 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 25.0
Subtracting 90 from 90 leaves us with 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 18

Moving on to step 4:
If we divide 7 by 18, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 250.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 18

Let's proceed to step 5:
The number 18 fits into 71 3 times, leaving a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 2503.0
The remainder is 17 after subtracting 54 from 71.
Take the next digit (7) from the dividend and append it to 17, then repeat: 177 / 18

Step 6:
177 divided by 18 is 9 with a remainder of 15.
Record the quotient 9 as the next digit in the result. 
Result so far: 25039.0
The remainder is 15 after subtracting 162 from 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
18 can be fit into 150 8 times, resulting in a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 25039.8
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.

Moving on to step 8:
If we divide 60 by 18, we get 3 and a remainder of 6.
The next digit of our result is 3. 
Result so far: 25039.83
If we take 54 away from 60, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
18 can be fit into 60 3 times, resulting in a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 25039.833
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.

After the division, we end up with 25039.833 and a remainder of 0.0006.
