28104 ÷ 13 
Let's see how many times 13 fits into 28104.

Moving on to step 1:
When dividing 2 by 13, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 13

Going ahead to step 2:
28 divided by 13 is 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 26 away from 28, we end up with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 13

Advancing to step 3:
If we divide 21 by 13, we get 1 and a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
If we take 13 away from 21, we end up with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 13

Step 4:
13 can be fit into 80 6 times, resulting in a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 216.0
Subtract 78 from 80 to get 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 13

On to step 5:
24 divided by 13 is 1 with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 2161.0
Deduct 13 from 24 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 6:
110 divided by 13 is 8 with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 2161.8
Subtract 104 from 110 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
13 can be fit into 60 4 times, resulting in a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 2161.84
The remainder is 8 after subtracting 52 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 8:
13 can be fit into 80 6 times, resulting in a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 2161.846
Subtracting 78 from 80 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 9:
The number 13 fits into 20 1 times, leaving a remainder of 7.
The next digit of our result is 1. 
Result so far: 2161.8461
Deduct 13 from 20 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 10:
The number 13 fits into 70 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 2161.84615
If we take 65 away from 70, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 11:
13 goes into 50 3 times with a remainder of 11.
The next digit of our result is 3. 
Result so far: 2161.846153
If we take 39 away from 50, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 12:
110 divided by 13 is 8 with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 2161.8461538
The remainder is 6 after subtracting 104 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 13:
13 goes into 60 4 times with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 2161.84615384
If we subtract 52 from 60, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 2161.84615384 with a remaining 8e-09.
