We divide 406458 by 18
We're looking to find how many times 18 goes into 406458.

Advancing 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
If we subtract 0 from 4, we get 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 18

Moving on to step 2:
When dividing 40 by 18, we get 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 36 from 40 and we're left with 4.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 18

On to step 3:
18 can be fit into 46 2 times, resulting in a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 22.0
If we take 36 away from 46, we end up with 10.
Take the next digit (4) from the dividend and append it to 10, then repeat: 104 / 18

Step 4:
If we divide 104 by 18, we get 5 and a remainder of 14.
Write down 5 as next digit of the result. 
Result so far: 225.0
If we take 90 away from 104, we end up with 14.
Bring next digit (5) of the dividend behind the 14 and repeat the process: 145 / 18

Step 5:
If we divide 145 by 18, we get 8 and a remainder of 1.
The next digit of our result is 8. 
Result so far: 2258.0
Subtracting 144 from 145 leaves us with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 18

Step 6:
18 divided by 18 is 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 22581.0
Subtracting 18 from 18 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
If we divide 0 by 18, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 22581.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
18 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 22581.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 22581.0, and the remainder is 0.0.
