We look at the division of 455777 by 18 
We want to figure out the number of times 455777 can be divided by 18.

Step 1:
4 divided by 18 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 18

On to step 2:
18 goes into 45 2 times with a remainder of 9.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 9 after subtracting 36 from 45.
Append the next digit (5) from the dividend to 9 and continue with: 95 / 18

Moving on to step 3:
The number 18 fits into 95 5 times, leaving a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 25.0
Subtracting 90 from 95 leaves us with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 18

On to step 4:
When dividing 57 by 18, we get 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 253.0
Subtract 54 from 57 to get 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 18

On to step 5:
When dividing 37 by 18, we get 2 with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2532.0
The remainder is 1 after subtracting 36 from 37.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 18

Advancing to step 6:
If we divide 17 by 18, we get 0 and a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 25320.0
The remainder is 17 after subtracting 0 from 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 7:
If we divide 170 by 18, we get 9 and a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 25320.9
Subtract 162 from 170 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 8:
18 goes into 80 4 times with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 25320.94
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
80 divided by 18 is 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 25320.944
Deduct 72 from 80 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 25320.944 with a remaining 0.0008.
