We're dividing 531045 by 18 
Our goal is to divide 531045 by 18.

Step 1:
18 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 18

Moving on to step 2:
53 divided by 18 is 2 with a remainder of 17.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 36 from 53 leaves us with 17.
Take the next digit (1) from the dividend and append it to 17, then repeat: 171 / 18

On to step 3:
The number 18 fits into 171 9 times, leaving a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 29.0
If we subtract 162 from 171, we get 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 18

Step 4:
18 goes into 90 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 295.0
Subtract 90 from 90 to get 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 18

Moving on to step 5:
18 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 2950.0
Subtract 0 from 4 to get 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 18

Going ahead to step 6:
18 can be fit into 45 2 times, resulting in a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 29502.0
If we subtract 36 from 45, we 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.

Step 7:
When dividing 90 by 18, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 29502.5
Subtracting 90 from 90 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 8:
18 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 29502.5
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.

Step 9:
18 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 29502.5
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.

The final result is 29502.5 with a remainder of 0.0.
