Let's divide 212009 by 17
Our goal is to divide 212009 by 17.

On to step 1:
17 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 17

Step 2:
If we divide 21 by 17, we get 1 and a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 17 from 21 and we're left with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 17

On to step 3:
If we divide 42 by 17, we get 2 and a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 8 after subtracting 34 from 42.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 17

Going ahead to step 4:
17 goes into 80 4 times with a remainder of 12.
The next digit of our result is 4. 
Result so far: 124.0
If we subtract 68 from 80, we get 12.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 17

Advancing to step 5:
The number 17 fits into 120 7 times, leaving a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 1247.0
The remainder is 1 after subtracting 119 from 120.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 17

Step 6:
17 goes into 19 1 times with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 12471.0
Subtracting 17 from 19 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:
20 divided by 17 is 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 12471.1
Deduct 17 from 20 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 8:
17 goes into 30 1 times with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 12471.11
Subtract 17 from 30 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Our division results in 12471.11 with a remaining 0.013.
