We look at the division of 510311 by 28 
We're looking to find how many times 28 goes into 510311.

Going ahead to step 1:
If we divide 5 by 28, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 28

On to step 2:
51 divided by 28 is 1 with a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 28 away from 51, we end up with 23.
Grab the next digit (0) from the dividend, add it to 23, then carry on: 230 / 28

Advancing to step 3:
230 divided by 28 is 8 with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
If we take 224 away from 230, we end up with 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 28

Advancing to step 4:
63 divided by 28 is 2 with a remainder of 7.
The next digit of our result is 2. 
Result so far: 182.0
Subtract 56 from 63 to get 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 28

Moving on to step 5:
If we divide 71 by 28, we get 2 and a remainder of 15.
Write down 2 as next digit of the result. 
Result so far: 1822.0
The remainder is 15 after subtracting 56 from 71.
Take the next digit (1) from the dividend and append it to 15, then repeat: 151 / 28

Advancing to step 6:
The number 28 fits into 151 5 times, leaving a remainder of 11.
Write down 5 as next digit of the result. 
Result so far: 18225.0
Subtracting 140 from 151 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 7:
110 divided by 28 is 3 with a remainder of 26.
The next digit of our result is 3. 
Result so far: 18225.3
Subtracting 84 from 110 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 8:
If we divide 260 by 28, we get 9 and a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 18225.39
Deduct 252 from 260 and we're left 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.

Moving on to step 9:
28 goes into 80 2 times with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 18225.392
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.

Moving on to step 10:
28 can be fit into 240 8 times, resulting in a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 18225.3928
Subtracting 224 from 240 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 11:
28 goes into 160 5 times with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 18225.39285
Subtracting 140 from 160 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 12:
28 can be fit into 200 7 times, resulting in a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 18225.392857
The remainder is 4 after subtracting 196 from 200.
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 13:
28 goes into 40 1 times with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 18225.3928571
Deduct 28 from 40 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.

Let's proceed to step 14:
If we divide 120 by 28, we get 4 and a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 18225.39285714
Subtracting 112 from 120 leaves us 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.

The final result is 18225.39285714 with a remainder of 8e-09.
