728813 divided by 28 
Let's see how many times 28 fits into 728813.

Let's proceed to step 1:
28 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 28

Going ahead to step 2:
If we divide 72 by 28, we get 2 and a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 56 from 72 to get 16.
Fetch the next digit (8) from the dividend, attach it to 16 and continue: 168 / 28

On to step 3:
The number 28 fits into 168 6 times, leaving a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 26.0
Subtract 168 from 168 to get 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 28

Moving on to step 4:
8 divided by 28 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 260.0
If we take 0 away from 8, we end up with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 28

Advancing to step 5:
When dividing 81 by 28, we get 2 with a remainder of 25.
Write down 2 as next digit of the result. 
Result so far: 2602.0
Subtract 56 from 81 to get 25.
Include the next digit (3) from the dividend after 25, then repeat: 253 / 28

Advancing to step 6:
The number 28 fits into 253 9 times, leaving a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 26029.0
Subtract 252 from 253 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
When dividing 10 by 28, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 26029.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
If we divide 100 by 28, we get 3 and a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 26029.03
Subtracting 84 from 100 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.

Moving on to step 9:
The number 28 fits into 160 5 times, leaving a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 26029.035
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 10:
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: 26029.0357
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.

Step 11:
The number 28 fits into 40 1 times, leaving a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 26029.03571
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.

On to step 12:
120 divided by 28 is 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 26029.035714
If we subtract 112 from 120, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 13:
The number 28 fits into 80 2 times, leaving a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 26029.0357142
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.

Let's proceed to step 14:
28 goes into 240 8 times with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 26029.03571428
Subtract 224 from 240 to 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.

After the division, we end up with 26029.03571428 and a remainder of 1.6e-08.
