515038 divided by 28 
We're looking to find how many times 28 goes into 515038.

Let's proceed to step 1:
5 divided by 28 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 28

Let's proceed to step 2:
The number 28 fits into 51 1 times, leaving a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 28 from 51 to get 23.
Take the next digit (5) from the dividend and append it to 23, then repeat: 235 / 28

Advancing to step 3:
235 divided by 28 is 8 with a remainder of 11.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Subtract 224 from 235 to get 11.
Take the next digit (0) from the dividend and append it to 11, then repeat: 110 / 28

Let's proceed to step 4:
28 can be fit into 110 3 times, resulting in a remainder of 26.
Write down 3 as next digit of the result. 
Result so far: 183.0
The remainder is 26 after subtracting 84 from 110.
Include the next digit (3) from the dividend after 26, then repeat: 263 / 28

Going ahead to step 5:
When dividing 263 by 28, we get 9 with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 1839.0
Subtracting 252 from 263 leaves us with 11.
Fetch the next digit (8) from the dividend, attach it to 11 and continue: 118 / 28

Let's proceed to step 6:
28 goes into 118 4 times with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 18394.0
If we subtract 112 from 118, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
The number 28 fits into 60 2 times, leaving a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 18394.2
Subtract 56 from 60 to 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.

Step 8:
When dividing 40 by 28, we get 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 18394.21
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.

Step 9:
120 divided by 28 is 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 18394.214
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.

Going ahead to step 10:
28 can be fit into 80 2 times, resulting in a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 18394.2142
Subtracting 56 from 80 leaves us 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.

Going ahead to step 11:
The number 28 fits into 240 8 times, leaving a remainder of 16.
The next digit of our result is 8. 
Result so far: 18394.21428
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 12:
160 divided by 28 is 5 with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 18394.214285
If we take 140 away from 160, we end up 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.

Going ahead to step 13:
When dividing 200 by 28, we get 7 with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 18394.2142857
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.

Going ahead to step 14:
When dividing 40 by 28, we get 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 18394.21428571
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.

The final outcome is 18394.21428571, with a leftover of 1.2e-08.
