We look at the division of 214090 by 3 
Let's see how many times 3 fits into 214090.

Going ahead 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
Subtracting 0 from 2 leaves us with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 3

On to step 2:
3 goes into 21 7 times with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 21 from 21 and we're left with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 3

On to step 3:
3 can be fit into 4 1 times, resulting in a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 71.0
If we take 3 away from 4, we end up with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 3

Going ahead to step 4:
The number 3 fits into 10 3 times, leaving a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 713.0
Deduct 9 from 10 and we're left with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 3

Step 5:
The number 3 fits into 19 6 times, leaving a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 7136.0
If we take 18 away from 19, we end up with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 3

Going ahead to step 6:
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: 71363.0
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.

Going ahead to step 7:
3 goes into 10 3 times with a remainder of 1.
The next digit of our result is 3. 
Result so far: 71363.3
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.

On to step 8:
10 divided by 3 is 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 71363.33
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.

The final result is 71363.33 with a remainder of 0.001.
