We divide 2800 by 3
Let's see how many times 3 fits into 2800.

Advancing to step 1:
If we divide 2 by 3, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 3

Advancing to step 2:
The number 3 fits into 28 9 times, leaving a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 27 from 28 to get 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 3

Advancing to step 3:
10 divided by 3 is 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 93.0
Deduct 9 from 10 and we're left with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 3

Advancing to step 4:
10 divided by 3 is 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 933.0
Deduct 9 from 10 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 5:
The number 3 fits into 10 3 times, leaving a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 933.3
Deduct 9 from 10 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 6:
3 can be fit into 10 3 times, resulting in a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 933.33
If we subtract 9 from 10, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Our division results in 933.33 with a remaining 0.001.
