278102 ÷ 99 
We want to divide 278102 by 99.

Step 1:
99 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 99

Step 2:
99 can be fit into 27 0 times, resulting in a remainder of 27.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 27, we get 27.
Bring next digit (8) of the dividend behind the 27 and repeat the process: 278 / 99

Moving on to step 3:
If we divide 278 by 99, we get 2 and a remainder of 80.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 198 away from 278, we end up with 80.
Include the next digit (1) from the dividend after 80, then repeat: 801 / 99

Going ahead to step 4:
If we divide 801 by 99, we get 8 and a remainder of 9.
Write down 8 as next digit of the result. 
Result so far: 28.0
Subtract 792 from 801 to get 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 99

Let's proceed to step 5:
The number 99 fits into 90 0 times, leaving a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 280.0
Subtract 0 from 90 to get 90.
Append the next digit (2) from the dividend to 90 and continue with: 902 / 99

Going ahead to step 6:
When dividing 902 by 99, we get 9 with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 2809.0
Deduct 891 from 902 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.

Let's proceed to step 7:
When dividing 110 by 99, we get 1 with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 2809.1
If we subtract 99 from 110, we get 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 8:
99 goes into 110 1 times with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 2809.11
If we subtract 99 from 110, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

After the division, we end up with 2809.11 and a remainder of 0.011.
