454420 ÷ 18 
We want to figure out the number of times 454420 can be divided by 18.

Advancing to step 1:
When dividing 4 by 18, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 18

On to 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
If we take 36 away from 45, we end up with 9.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 18

Let's proceed to step 3:
94 divided by 18 is 5 with a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Deduct 90 from 94 and we're left with 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 18

Step 4:
If we divide 44 by 18, we get 2 and a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 252.0
If we take 36 away from 44, we end up with 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 18

Step 5:
The number 18 fits into 82 4 times, leaving a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 2524.0
Deduct 72 from 82 and we're left with 10.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 18

Let's proceed to step 6:
The number 18 fits into 100 5 times, leaving a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 25245.0
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
18 goes into 100 5 times with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 25245.5
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
The number 18 fits into 100 5 times, leaving a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 25245.55
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 25245.55 and a remainder of 0.01.
