28251230 ÷ 321 
We want to divide 28251230 by 321.

Advancing to step 1:
321 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 321

Let's proceed to step 2:
28 divided by 321 is 0 with a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 28, we end up with 28.
Fetch the next digit (2) from the dividend, attach it to 28 and continue: 282 / 321

Step 3:
321 goes into 282 0 times with a remainder of 282.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 282 to get 282.
Take the next digit (5) from the dividend and append it to 282, then repeat: 2825 / 321

Moving on to step 4:
When dividing 2825 by 321, we get 8 with a remainder of 257.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 2568 from 2825, we get 257.
Bring next digit (1) of the dividend behind the 257 and repeat the process: 2571 / 321

Advancing to step 5:
When dividing 2571 by 321, we get 8 with a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 88.0
If we take 2568 away from 2571, we end up with 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 321

Moving on to step 6:
321 can be fit into 32 0 times, resulting in a remainder of 32.
Record the quotient 0 as the next digit in the result. 
Result so far: 880.0
The remainder is 32 after subtracting 0 from 32.
Grab the next digit (3) from the dividend, add it to 32, then carry on: 323 / 321

Advancing to step 7:
321 goes into 323 1 times with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 8801.0
If we take 321 away from 323, we end up with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 321

Step 8:
321 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 88010.0
Subtracting 0 from 20 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 9:
If we divide 200 by 321, we get 0 and a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 88010.0
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 10:
If we divide 2000 by 321, we get 6 and a remainder of 74.
Write down 6 as next digit of the result. 
Result so far: 88010.06
Subtract 1926 from 2000 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 11:
321 can be fit into 740 2 times, resulting in a remainder of 98.
The number 2 becomes the next digit in our result. 
Result so far: 88010.062
Deduct 642 from 740 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Step 12:
980 divided by 321 is 3 with a remainder of 17.
The next digit of our result is 3. 
Result so far: 88010.0623
Deduct 963 from 980 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 13:
321 goes into 170 0 times with a remainder of 170.
The next digit of our result is 0. 
Result so far: 88010.0623
Deduct 0 from 170 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

On to step 14:
321 goes into 1700 5 times with a remainder of 95.
Use 5 as the next digit of our solution. 
Result so far: 88010.062305
Subtract 1605 from 1700 to get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Let's proceed to step 15:
If we divide 950 by 321, we get 2 and a remainder of 308.
The number 2 becomes the next digit in our result. 
Result so far: 88010.0623052
Subtract 642 from 950 to get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Step 16:
When dividing 3080 by 321, we get 9 with a remainder of 191.
Record the quotient 9 as the next digit in the result. 
Result so far: 88010.06230529
Deduct 2889 from 3080 and we're left with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

The quotient of the division is 88010.06230529, and the remainder is 1.91e-07.
