30813299 ÷ 28 
Let's see how many times 28 fits into 30813299.

Moving on to step 1:
28 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 28

Moving on to step 2:
When dividing 30 by 28, we get 1 with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 28 from 30 to get 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 28

Moving on to step 3:
When dividing 28 by 28, we get 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we take 28 away from 28, we end up with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 28

On to step 4:
28 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 110.0
Subtract 0 from 1 to get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 28

Advancing to step 5:
The number 28 fits into 13 0 times, leaving a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 1100.0
Subtract 0 from 13 to get 13.
Bring next digit (2) of the dividend behind the 13 and repeat the process: 132 / 28

Going ahead to step 6:
132 divided by 28 is 4 with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 11004.0
Subtract 112 from 132 to get 20.
Include the next digit (9) from the dividend after 20, then repeat: 209 / 28

Going ahead to step 7:
When dividing 209 by 28, we get 7 with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 110047.0
If we take 196 away from 209, we end up with 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 28

On to step 8:
If we divide 139 by 28, we get 4 and a remainder of 27.
The next digit of our result is 4. 
Result so far: 1100474.0
Subtracting 112 from 139 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 9:
If we divide 270 by 28, we get 9 and a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 1100474.9
If we take 252 away from 270, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 10:
28 can be fit into 180 6 times, resulting in a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 1100474.96
Deduct 168 from 180 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.

Advancing to step 11:
120 divided by 28 is 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 1100474.964
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.

Let's proceed to step 12:
If we divide 80 by 28, we get 2 and a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 1100474.9642
If we take 56 away from 80, we end up 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 13:
If we divide 240 by 28, we get 8 and a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 1100474.96428
If we subtract 224 from 240, we 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.

Moving on to step 14:
160 divided by 28 is 5 with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 1100474.964285
The remainder is 20 after subtracting 140 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 15:
The number 28 fits into 200 7 times, leaving a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 1100474.9642857
Subtracting 196 from 200 leaves us 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.

Advancing to step 16:
28 can be fit into 40 1 times, resulting in a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 1100474.96428571
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.

After the division, we end up with 1100474.96428571 and a remainder of 1.2e-08.
