We look at the division of 513008 by 28 
Let's see how many times 28 fits into 513008.

Advancing to step 1:
The number 28 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 28

Going ahead to step 2:
51 divided by 28 is 1 with a remainder of 23.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 28 from 51, we get 23.
Include the next digit (3) from the dividend after 23, then repeat: 233 / 28

Step 3:
28 goes into 233 8 times with a remainder of 9.
Use 8 as the next digit of our solution. 
Result so far: 18.0
If we subtract 224 from 233, we get 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 28

Let's proceed to step 4:
The number 28 fits into 90 3 times, leaving a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 183.0
If we subtract 84 from 90, we get 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 28

Advancing to step 5:
If we divide 60 by 28, we get 2 and a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 1832.0
Subtract 56 from 60 to get 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 28

Step 6:
If we divide 48 by 28, we get 1 and a remainder of 20.
The next digit of our result is 1. 
Result so far: 18321.0
The remainder is 20 after subtracting 28 from 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 7:
200 divided by 28 is 7 with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 18321.7
Subtracting 196 from 200 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
28 goes into 40 1 times with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 18321.71
Subtracting 28 from 40 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.

On to step 9:
28 goes into 120 4 times with a remainder of 8.
The next digit of our result is 4. 
Result so far: 18321.714
If we take 112 away from 120, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
The number 28 fits into 80 2 times, leaving a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 18321.7142
Deduct 56 from 80 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 11:
When dividing 240 by 28, we get 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 18321.71428
If we subtract 224 from 240, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 12:
If we divide 160 by 28, we get 5 and a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 18321.714285
The remainder is 20 after subtracting 140 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 13:
28 goes into 200 7 times with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 18321.7142857
Deduct 196 from 200 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 14:
28 can be fit into 40 1 times, resulting in a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 18321.71428571
Subtract 28 from 40 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.

Our division results in 18321.71428571 with a remaining 1.2e-08.
