507693 ÷ 18 
Our goal is to divide 507693 by 18.

Step 1:
18 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 18

Going ahead to step 2:
50 divided by 18 is 2 with a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 36 from 50 and we're left with 14.
Fetch the next digit (7) from the dividend, attach it to 14 and continue: 147 / 18

Let's proceed to step 3:
If we divide 147 by 18, we get 8 and a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
If we subtract 144 from 147, we get 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 18

Advancing to step 4:
If we divide 36 by 18, we get 2 and a remainder of 0.
The next digit of our result is 2. 
Result so far: 282.0
The remainder is 0 after subtracting 36 from 36.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 18

Moving on to step 5:
When dividing 9 by 18, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 2820.0
If we take 0 away from 9, we end up with 9.
Bring next digit (3) of the dividend behind the 9 and repeat the process: 93 / 18

On to step 6:
The number 18 fits into 93 5 times, leaving a remainder of 3.
The next digit of our result is 5. 
Result so far: 28205.0
The remainder is 3 after subtracting 90 from 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
When dividing 30 by 18, we get 1 with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 28205.1
Subtracting 18 from 30 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 8:
The number 18 fits into 120 6 times, leaving a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 28205.16
Deduct 108 from 120 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
The number 18 fits into 120 6 times, leaving a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 28205.166
Subtract 108 from 120 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 28205.166 and a remainder of 0.0012.
