216236 divided by 3 
We want to divide 216236 by 3.

On to step 1:
2 divided by 3 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 3

On to step 2:
21 divided by 3 is 7 with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 21 from 21 leaves us with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 3

Going ahead to step 3:
3 goes into 6 2 times with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 72.0
If we take 6 away from 6, we end up with 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 3

Moving on to step 4:
The number 3 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 720.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 3

Step 5:
If we divide 23 by 3, we get 7 and a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 7207.0
If we take 21 away from 23, we end up with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 3

Going ahead to step 6:
If we divide 26 by 3, we get 8 and a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 72078.0
Subtracting 24 from 26 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 7:
The number 3 fits into 20 6 times, leaving a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 72078.6
If we take 18 away from 20, we end up 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.

On to step 8:
20 divided by 3 is 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 72078.66
Deduct 18 from 20 and we're left 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.

After the division, we end up with 72078.66 and a remainder of 0.002.
