451611 divided by 18 
Our goal is to divide 451611 by 18.

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.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 18

Going ahead 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
If we take 36 away from 45, we end up with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 18

Advancing to step 3:
The number 18 fits into 91 5 times, leaving a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
If we take 90 away from 91, we end up with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 18

Going ahead to step 4:
If we divide 16 by 18, we get 0 and a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 250.0
Subtract 0 from 16 to get 16.
Append the next digit (1) from the dividend to 16 and continue with: 161 / 18

Let's proceed to step 5:
If we divide 161 by 18, we get 8 and a remainder of 17.
The number 8 becomes the next digit in our result. 
Result so far: 2508.0
If we subtract 144 from 161, we get 17.
Grab the next digit (1) from the dividend, add it to 17, then carry on: 171 / 18

Step 6:
171 divided by 18 is 9 with a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 25089.0
Subtract 162 from 171 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
90 divided by 18 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 25089.5
Deduct 90 from 90 and we're left 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.

Going ahead to step 8:
When dividing 0 by 18, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 25089.5
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
0 divided by 18 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 25089.5
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.

In conclusion, the division gives 25089.5 with a balance of 0.0.
