Let's divide 458886 by 18
We want to figure out the number of times 458886 can be divided by 18.

Let's proceed to step 1:
If we divide 4 by 18, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 18

Moving on to step 2:
45 divided by 18 is 2 with 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 (8) from the dividend and append it to 9, then repeat: 98 / 18

Advancing to step 3:
The number 18 fits into 98 5 times, leaving a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
If we take 90 away from 98, we end up with 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 18

Let's proceed to step 4:
18 can be fit into 88 4 times, resulting in a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 254.0
Subtract 72 from 88 to get 16.
Bring next digit (8) of the dividend behind the 16 and repeat the process: 168 / 18

Step 5:
18 goes into 168 9 times with a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 2549.0
Subtracting 162 from 168 leaves us with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 18

Step 6:
The number 18 fits into 66 3 times, leaving a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 25493.0
If we take 54 away from 66, we end up 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 7:
18 can be fit into 120 6 times, resulting in a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 25493.6
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.

Let's proceed to step 8:
18 can be fit into 120 6 times, resulting in a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 25493.66
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.

After the division, we end up with 25493.66 and a remainder of 0.012.
