We look at the division of 34090 by 17 
Let's see how many times 17 fits into 34090.

On to step 1:
When dividing 3 by 17, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 17

Moving on to step 2:
When dividing 34 by 17, we get 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 34 from 34 and we're left with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 17

Going ahead to step 3:
If we divide 0 by 17, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
If we take 0 away from 0, we end up with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 17

On to step 4:
If we divide 9 by 17, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 200.0
If we take 0 away from 9, we end up with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 17

Moving on to step 5:
When dividing 90 by 17, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 2005.0
If we subtract 85 from 90, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 6:
The number 17 fits into 50 2 times, leaving a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 2005.2
Deduct 34 from 50 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 7:
If we divide 160 by 17, we get 9 and a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 2005.29
Deduct 153 from 160 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 8:
17 can be fit into 70 4 times, resulting in a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 2005.294
Deduct 68 from 70 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.

On to step 9:
When dividing 20 by 17, we get 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 2005.2941
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 10:
When dividing 30 by 17, we get 1 with a remainder of 13.
The next digit of our result is 1. 
Result so far: 2005.29411
Subtracting 17 from 30 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final result is 2005.29411 with a remainder of 1.3e-05.
