304039 divided by 28 
We want to figure out the number of times 304039 can be divided by 28.

Step 1:
3 divided by 28 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 28

On to step 2:
The number 28 fits into 30 1 times, leaving a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 28 away from 30, we end up with 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 28

Let's proceed to step 3:
The number 28 fits into 24 0 times, leaving a remainder of 24.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 24, we get 24.
Take the next digit (0) from the dividend and append it to 24, then repeat: 240 / 28

Advancing to step 4:
28 can be fit into 240 8 times, resulting in a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 108.0
If we take 224 away from 240, we end up with 16.
Fetch the next digit (3) from the dividend, attach it to 16 and continue: 163 / 28

Advancing to step 5:
28 goes into 163 5 times with a remainder of 23.
The number 5 becomes the next digit in our result. 
Result so far: 1085.0
The remainder is 23 after subtracting 140 from 163.
Take the next digit (9) from the dividend and append it to 23, then repeat: 239 / 28

Advancing to step 6:
The number 28 fits into 239 8 times, leaving a remainder of 15.
Use 8 as the next digit of our solution. 
Result so far: 10858.0
Deduct 224 from 239 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 7:
When dividing 150 by 28, we get 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 10858.5
If we take 140 away from 150, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
28 goes into 100 3 times with a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 10858.53
Subtract 84 from 100 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.

Going ahead to step 9:
When dividing 160 by 28, we get 5 with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 10858.535
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.

Advancing to step 10:
28 goes into 200 7 times with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 10858.5357
Subtract 196 from 200 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.

On to step 11:
40 divided by 28 is 1 with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 10858.53571
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.

Let's proceed to step 12:
120 divided by 28 is 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 10858.535714
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.

Let's proceed to step 13:
80 divided by 28 is 2 with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 10858.5357142
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.

Moving on to step 14:
28 can be fit into 240 8 times, resulting in a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 10858.53571428
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 10858.53571428 and a remainder of 1.6e-08.
