We're dividing 348790 by 17 
Let's see how many times 17 fits into 348790.

Going ahead to step 1:
When dividing 3 by 17, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 17

Moving on to step 2:
17 can be fit into 34 2 times, resulting in a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 34 away from 34, we end up with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 17

Going ahead to step 3:
When dividing 8 by 17, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 17

Let's proceed to step 4:
The number 17 fits into 87 5 times, leaving a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 205.0
If we subtract 85 from 87, we get 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 17

Step 5:
17 goes into 29 1 times with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 2051.0
If we take 17 away from 29, we end up with 12.
Append the next digit (0) from the dividend to 12 and continue with: 120 / 17

Going ahead to step 6:
17 goes into 120 7 times with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 20517.0
If we take 119 away from 120, 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.

Advancing to step 7:
The number 17 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 20517.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
17 goes into 100 5 times with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 20517.05
Subtracting 85 from 100 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 9:
The number 17 fits into 150 8 times, leaving a remainder of 14.
The next digit of our result is 8. 
Result so far: 20517.058
Deduct 136 from 150 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 10:
140 divided by 17 is 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 20517.0588
Subtracting 136 from 140 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 20517.0588 with a remainder of 4e-05.
