456394 ÷ 18 
We're looking to find how many times 18 goes into 456394.

On to step 1:
If we divide 4 by 18, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 18

Going ahead to step 2:
The number 18 fits into 45 2 times, leaving 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.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 18

On to step 3:
18 can be fit into 96 5 times, resulting in a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Deduct 90 from 96 and we're left with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 18

Advancing to step 4:
The number 18 fits into 63 3 times, leaving a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 253.0
Subtract 54 from 63 to get 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 18

Step 5:
18 can be fit into 99 5 times, resulting in a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 2535.0
Subtracting 90 from 99 leaves us with 9.
Fetch the next digit (4) from the dividend, attach it to 9 and continue: 94 / 18

Moving on to step 6:
18 can be fit into 94 5 times, resulting in a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 25355.0
Subtracting 90 from 94 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
18 goes into 40 2 times with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 25355.2
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
If we divide 40 by 18, we get 2 and a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 25355.22
Subtracting 36 from 40 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 25355.22 with a remaining 0.004.
