453443 divided by 18 
We're looking to find how many times 18 goes into 453443.

Going ahead to step 1:
4 divided by 18 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 18

Let's proceed to step 2:
If we divide 45 by 18, we get 2 and 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.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 18

Advancing to step 3:
When dividing 93 by 18, we get 5 with a remainder of 3.
The next digit of our result is 5. 
Result so far: 25.0
Subtract 90 from 93 to get 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 18

Going ahead to step 4:
If we divide 34 by 18, we get 1 and a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 251.0
If we take 18 away from 34, we end up with 16.
Fetch the next digit (4) from the dividend, attach it to 16 and continue: 164 / 18

On to step 5:
The number 18 fits into 164 9 times, leaving a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 2519.0
If we subtract 162 from 164, we get 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 18

On to step 6:
If we divide 23 by 18, we get 1 and a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 25191.0
The remainder is 5 after subtracting 18 from 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
If we divide 50 by 18, we get 2 and a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 25191.2
If we take 36 away from 50, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 8:
18 can be fit into 140 7 times, resulting in a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 25191.27
Subtracting 126 from 140 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 9:
The number 18 fits into 140 7 times, leaving a remainder of 14.
The next digit of our result is 7. 
Result so far: 25191.277
If we take 126 away from 140, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

In conclusion, the division gives 25191.277 with a balance of 0.0014.
