We look at the division of 211555 by 3 
Let's see how many times 3 fits into 211555.

On to step 1:
The number 3 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 3

Moving on to step 2:
21 divided by 3 is 7 with a remainder of 0.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 21 from 21 and we're left with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 3

On to step 3:
When dividing 1 by 3, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 70.0
Subtract 0 from 1 to get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 3

Step 4:
The number 3 fits into 15 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 705.0
The remainder is 0 after subtracting 15 from 15.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 3

Going ahead to step 5:
5 divided by 3 is 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 7051.0
If we take 3 away from 5, we end up with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 3

Going ahead to step 6:
3 goes into 25 8 times with a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 70518.0
Deduct 24 from 25 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.

Going ahead to step 7:
When dividing 10 by 3, we get 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 70518.3
Subtract 9 from 10 to 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.

Advancing to step 8:
If we divide 10 by 3, we get 3 and a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 70518.33
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.

Our division results in 70518.33 with a remaining 0.001.
