We're dividing 515363 by 28 
We want to divide 515363 by 28.

On to step 1:
The number 28 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 28

Advancing to step 2:
28 can be fit into 51 1 times, resulting in a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 28 away from 51, we end up with 23.
Include the next digit (5) from the dividend after 23, then repeat: 235 / 28

Let's proceed to step 3:
28 goes into 235 8 times with a remainder of 11.
Write down 8 as next digit of the result. 
Result so far: 18.0
The remainder is 11 after subtracting 224 from 235.
Append the next digit (3) from the dividend to 11 and continue with: 113 / 28

Moving on to step 4:
The number 28 fits into 113 4 times, leaving a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 184.0
The remainder is 1 after subtracting 112 from 113.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 28

Step 5:
28 goes into 16 0 times with a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 1840.0
The remainder is 16 after subtracting 0 from 16.
Fetch the next digit (3) from the dividend, attach it to 16 and continue: 163 / 28

Moving on to step 6:
If we divide 163 by 28, we get 5 and a remainder of 23.
Write down 5 as next digit of the result. 
Result so far: 18405.0
If we take 140 away from 163, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 7:
28 can be fit into 230 8 times, resulting in a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 18405.8
The remainder is 6 after subtracting 224 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
28 can be fit into 60 2 times, resulting in a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 18405.82
If we subtract 56 from 60, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
If we divide 40 by 28, we get 1 and a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 18405.821
The remainder is 12 after subtracting 28 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 10:
28 can be fit into 120 4 times, resulting in a remainder of 8.
The next digit of our result is 4. 
Result so far: 18405.8214
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.

On to step 11:
80 divided by 28 is 2 with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 18405.82142
Subtract 56 from 80 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 12:
If we divide 240 by 28, we get 8 and a remainder of 16.
The next digit of our result is 8. 
Result so far: 18405.821428
If we take 224 away from 240, we end up 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 13:
If we divide 160 by 28, we get 5 and a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 18405.8214285
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.

On to step 14:
28 goes into 200 7 times with a remainder of 4.
The next digit of our result is 7. 
Result so far: 18405.82142857
If we take 196 away from 200, we end up 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.

After the division, we end up with 18405.82142857 and a remainder of 4e-09.
