We look at the division of 28811027 by 399 
We're looking to find how many times 399 goes into 28811027.

Going ahead to step 1:
The number 399 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 399

Advancing to step 2:
The number 399 fits into 28 0 times, leaving a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Append the next digit (8) from the dividend to 28 and continue with: 288 / 399

Let's proceed to step 3:
If we divide 288 by 399, we get 0 and a remainder of 288.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 288 leaves us with 288.
Append the next digit (1) from the dividend to 288 and continue with: 2881 / 399

Going ahead to step 4:
If we divide 2881 by 399, we get 7 and a remainder of 88.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 2793 from 2881, we get 88.
Bring next digit (1) of the dividend behind the 88 and repeat the process: 881 / 399

Let's proceed to step 5:
The number 399 fits into 881 2 times, leaving a remainder of 83.
Write down 2 as next digit of the result. 
Result so far: 72.0
The remainder is 83 after subtracting 798 from 881.
Fetch the next digit (0) from the dividend, attach it to 83 and continue: 830 / 399

Let's proceed to step 6:
399 goes into 830 2 times with a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 722.0
Subtract 798 from 830 to get 32.
Append the next digit (2) from the dividend to 32 and continue with: 322 / 399

On to step 7:
When dividing 322 by 399, we get 0 with a remainder of 322.
Record the quotient 0 as the next digit in the result. 
Result so far: 7220.0
Subtracting 0 from 322 leaves us with 322.
Bring next digit (7) of the dividend behind the 322 and repeat the process: 3227 / 399

Let's proceed to step 8:
3227 divided by 399 is 8 with a remainder of 35.
Put 8 as the next digit of the answer. 
Result so far: 72208.0
Deduct 3192 from 3227 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 9:
399 can be fit into 350 0 times, resulting in a remainder of 350.
Put 0 as the next digit of the answer. 
Result so far: 72208.0
Subtracting 0 from 350 leaves us with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Advancing to step 10:
The number 399 fits into 3500 8 times, leaving a remainder of 308.
The next digit of our result is 8. 
Result so far: 72208.08
Subtracting 3192 from 3500 leaves us with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Going ahead to step 11:
3080 divided by 399 is 7 with a remainder of 287.
Write down 7 as next digit of the result. 
Result so far: 72208.087
Subtract 2793 from 3080 to get 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

Let's proceed to step 12:
The number 399 fits into 2870 7 times, leaving a remainder of 77.
Record the quotient 7 as the next digit in the result. 
Result so far: 72208.0877
If we subtract 2793 from 2870, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

After the division, we end up with 72208.0877 and a remainder of 0.00077.
