We're dividing 856 by 3 
We want to divide 856 by 3.

Step 1:
If we divide 8 by 3, we get 2 and a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 6 from 8 leaves us with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 3

Advancing to step 2:
The number 3 fits into 25 8 times, leaving a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 28.0
Subtract 24 from 25 to get 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 3

Advancing to step 3:
When dividing 16 by 3, we get 5 with a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 285.0
Subtracting 15 from 16 leaves us 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.

Let's proceed to step 4:
3 goes into 10 3 times with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 285.3
If we take 9 away from 10, we end up 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 5:
3 can be fit into 10 3 times, resulting in a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 285.33
Subtracting 9 from 10 leaves us 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.

The final result is 285.33 with a remainder of 0.001.
