We divide 515515 by 28
We're looking to find how many times 28 goes into 515515.

Let's proceed to step 1:
28 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 28

Let's proceed to step 2:
If we divide 51 by 28, we get 1 and a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 28 from 51 leaves us with 23.
Take the next digit (5) from the dividend and append it to 23, then repeat: 235 / 28

Let's proceed to step 3:
If we divide 235 by 28, we get 8 and a remainder of 11.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Subtracting 224 from 235 leaves us with 11.
Grab the next digit (5) from the dividend, add it to 11, then carry on: 115 / 28

Going ahead to step 4:
If we divide 115 by 28, we get 4 and a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 184.0
Subtracting 112 from 115 leaves us with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 28

Step 5:
The number 28 fits into 31 1 times, leaving a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1841.0
If we take 28 away from 31, we end up with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 28

Let's proceed to step 6:
35 divided by 28 is 1 with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 18411.0
If we take 28 away from 35, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
70 divided by 28 is 2 with a remainder of 14.
The next digit of our result is 2. 
Result so far: 18411.2
If we take 56 away from 70, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 8:
28 goes into 140 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 18411.25
Subtracting 140 from 140 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
28 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 18411.25
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
If we divide 0 by 28, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 18411.25
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 18411.25, with a leftover of 0.0.
