1 divided by 509 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 509

On to step 2:
509 goes into 18 0 times with a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Bring next digit (3) of the dividend behind the 18 and repeat the process: 183 / 509

Going ahead to step 3:
509 goes into 183 0 times with a remainder of 183.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 183 after subtracting 0 from 183.
Fetch the next digit (1) from the dividend, attach it to 183 and continue: 1831 / 509

Advancing to step 4:
The number 509 fits into 1831 3 times, leaving a remainder of 304.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 1527 from 1831 leaves us with 304.
Grab the next digit (5) from the dividend, add it to 304, then carry on: 3045 / 509

Step 5:
509 goes into 3045 5 times with a remainder of 500.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
Subtracting 2545 from 3045 leaves us with 500.
Include the next digit (2) from the dividend after 500, then repeat: 5002 / 509

Going ahead to step 6:
509 goes into 5002 9 times with a remainder of 421.
Write down 9 as next digit of the result. 
Result so far: 359.0
Subtracting 4581 from 5002 leaves us with 421.
Append the next digit (3) from the dividend to 421 and continue with: 4213 / 509

Advancing to step 7:
509 goes into 4213 8 times with a remainder of 141.
The number 8 becomes the next digit in our result. 
Result so far: 3598.0
If we subtract 4072 from 4213, we get 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

On to step 8:
The number 509 fits into 1410 2 times, leaving a remainder of 392.
Write down 2 as next digit of the result. 
Result so far: 3598.2
If we take 1018 away from 1410, we end up with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Advancing to step 9:
509 goes into 3920 7 times with a remainder of 357.
The number 7 becomes the next digit in our result. 
Result so far: 3598.27
Deduct 3563 from 3920 and we're left with 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

Step 10:
The number 509 fits into 3570 7 times, leaving a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 3598.277
The remainder is 7 after subtracting 3563 from 3570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

After the division, we end up with 3598.277 and a remainder of 0.0007.
