We're dividing 28396503 by 321 
Let's see how many times 321 fits into 28396503.

Moving on to step 1:
The number 321 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.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 321

Going ahead to step 2:
321 can be fit into 28 0 times, resulting in 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.
Append the next digit (3) from the dividend to 28 and continue with: 283 / 321

Let's proceed to step 3:
283 divided by 321 is 0 with a remainder of 283.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 283 after subtracting 0 from 283.
Fetch the next digit (9) from the dividend, attach it to 283 and continue: 2839 / 321

Step 4:
2839 divided by 321 is 8 with a remainder of 271.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 2568 from 2839 and we're left with 271.
Fetch the next digit (6) from the dividend, attach it to 271 and continue: 2716 / 321

Step 5:
The number 321 fits into 2716 8 times, leaving a remainder of 148.
Write down 8 as next digit of the result. 
Result so far: 88.0
Subtract 2568 from 2716 to get 148.
Take the next digit (5) from the dividend and append it to 148, then repeat: 1485 / 321

Advancing to step 6:
If we divide 1485 by 321, we get 4 and a remainder of 201.
Use 4 as the next digit of our solution. 
Result so far: 884.0
Subtract 1284 from 1485 to get 201.
Append the next digit (0) from the dividend to 201 and continue with: 2010 / 321

On to step 7:
The number 321 fits into 2010 6 times, leaving a remainder of 84.
The number 6 becomes the next digit in our result. 
Result so far: 8846.0
Deduct 1926 from 2010 and we're left with 84.
Take the next digit (3) from the dividend and append it to 84, then repeat: 843 / 321

Advancing to step 8:
321 can be fit into 843 2 times, resulting in a remainder of 201.
The number 2 becomes the next digit in our result. 
Result so far: 88462.0
If we subtract 642 from 843, we get 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Advancing to step 9:
321 can be fit into 2010 6 times, resulting in a remainder of 84.
Put 6 as the next digit of the answer. 
Result so far: 88462.6
If we subtract 1926 from 2010, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 10:
When dividing 840 by 321, we get 2 with a remainder of 198.
The next digit of our result is 2. 
Result so far: 88462.62
If we take 642 away from 840, we end up with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Step 11:
If we divide 1980 by 321, we get 6 and a remainder of 54.
Record the quotient 6 as the next digit in the result. 
Result so far: 88462.626
If we subtract 1926 from 1980, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 12:
321 goes into 540 1 times with a remainder of 219.
The number 1 becomes the next digit in our result. 
Result so far: 88462.6261
Subtracting 321 from 540 leaves us with 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Let's proceed to step 13:
If we divide 2190 by 321, we get 6 and a remainder of 264.
The number 6 becomes the next digit in our result. 
Result so far: 88462.62616
If we subtract 1926 from 2190, we get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

On to step 14:
When dividing 2640 by 321, we get 8 with a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 88462.626168
The remainder is 72 after subtracting 2568 from 2640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 15:
321 can be fit into 720 2 times, resulting in a remainder of 78.
Use 2 as the next digit of our solution. 
Result so far: 88462.6261682
The remainder is 78 after subtracting 642 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 16:
The number 321 fits into 780 2 times, leaving a remainder of 138.
Write down 2 as next digit of the result. 
Result so far: 88462.62616822
If we subtract 642 from 780, we get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

The final result is 88462.62616822 with a remainder of 1.38e-07.
