We're dividing 451293 by 18 
Our goal is to divide 451293 by 18.

Going ahead to step 1:
18 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 18

Advancing to step 2:
The number 18 fits into 45 2 times, leaving a remainder of 9.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 36 from 45 to get 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 18

Going ahead to step 3:
If we divide 91 by 18, we get 5 and a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Deduct 90 from 91 and we're left with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 18

Let's proceed to step 4:
When dividing 12 by 18, we get 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 250.0
If we take 0 away from 12, we end up with 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 18

Step 5:
129 divided by 18 is 7 with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 2507.0
Subtract 126 from 129 to get 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 18

Advancing to step 6:
33 divided by 18 is 1 with a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 25071.0
Deduct 18 from 33 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
18 goes into 150 8 times with a remainder of 6.
The next digit of our result is 8. 
Result so far: 25071.8
Subtracting 144 from 150 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
When dividing 60 by 18, we get 3 with a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 25071.83
If we take 54 away from 60, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 9:
When dividing 60 by 18, we get 3 with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 25071.833
If we take 54 away from 60, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

In conclusion, the division gives 25071.833 with a balance of 0.0006.
