28864807 ÷ 231 
Our goal is to divide 28864807 by 231.

Step 1:
2 divided by 231 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 231

On to step 2:
231 can be fit into 28 0 times, resulting in a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Bring next digit (8) of the dividend behind the 28 and repeat the process: 288 / 231

Step 3:
When dividing 288 by 231, we get 1 with a remainder of 57.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 231 from 288 and we're left with 57.
Bring next digit (6) of the dividend behind the 57 and repeat the process: 576 / 231

Advancing to step 4:
231 can be fit into 576 2 times, resulting in a remainder of 114.
The next digit of our result is 2. 
Result so far: 12.0
If we take 462 away from 576, we end up with 114.
Grab the next digit (4) from the dividend, add it to 114, then carry on: 1144 / 231

Moving on to step 5:
231 can be fit into 1144 4 times, resulting in a remainder of 220.
Record the quotient 4 as the next digit in the result. 
Result so far: 124.0
Subtract 924 from 1144 to get 220.
Grab the next digit (8) from the dividend, add it to 220, then carry on: 2208 / 231

On to step 6:
When dividing 2208 by 231, we get 9 with a remainder of 129.
Use 9 as the next digit of our solution. 
Result so far: 1249.0
Deduct 2079 from 2208 and we're left with 129.
Include the next digit (0) from the dividend after 129, then repeat: 1290 / 231

Step 7:
231 goes into 1290 5 times with a remainder of 135.
The number 5 becomes the next digit in our result. 
Result so far: 12495.0
If we subtract 1155 from 1290, we get 135.
Fetch the next digit (7) from the dividend, attach it to 135 and continue: 1357 / 231

Moving on to step 8:
1357 divided by 231 is 5 with a remainder of 202.
Use 5 as the next digit of our solution. 
Result so far: 124955.0
Subtract 1155 from 1357 to get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Going ahead to step 9:
2020 divided by 231 is 8 with a remainder of 172.
The next digit of our result is 8. 
Result so far: 124955.8
Deduct 1848 from 2020 and we're left with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

On to step 10:
The number 231 fits into 1720 7 times, leaving a remainder of 103.
The next digit of our result is 7. 
Result so far: 124955.87
Subtract 1617 from 1720 to get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Let's proceed to step 11:
231 can be fit into 1030 4 times, resulting in a remainder of 106.
Write down 4 as next digit of the result. 
Result so far: 124955.874
Subtract 924 from 1030 to get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Step 12:
The number 231 fits into 1060 4 times, leaving a remainder of 136.
The next digit of our result is 4. 
Result so far: 124955.8744
Subtract 924 from 1060 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

The quotient of the division is 124955.8744, and the remainder is 0.00136.
