We divide 490840 by 17
We want to figure out the number of times 490840 can be divided by 17.

Advancing to step 1:
17 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 17

Let's proceed to step 2:
When dividing 49 by 17, we get 2 with a remainder of 15.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 34 from 49 to get 15.
Take the next digit (0) from the dividend and append it to 15, then repeat: 150 / 17

Going ahead to step 3:
150 divided by 17 is 8 with a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 28.0
If we take 136 away from 150, we end up with 14.
Include the next digit (8) from the dividend after 14, then repeat: 148 / 17

Going ahead to step 4:
17 goes into 148 8 times with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 288.0
The remainder is 12 after subtracting 136 from 148.
Take the next digit (4) from the dividend and append it to 12, then repeat: 124 / 17

Going ahead to step 5:
124 divided by 17 is 7 with a remainder of 5.
The next digit of our result is 7. 
Result so far: 2887.0
If we subtract 119 from 124, we get 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 17

On to step 6:
The number 17 fits into 50 2 times, leaving a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 28872.0
Subtract 34 from 50 to get 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.
Use 9 as the next digit of our solution. 
Result so far: 28872.9
Subtracting 153 from 160 leaves us 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.

On to step 8:
If we divide 70 by 17, we get 4 and a remainder of 2.
The next digit of our result is 4. 
Result so far: 28872.94
Subtract 68 from 70 to get 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 9:
If we divide 20 by 17, we get 1 and a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 28872.941
Subtracting 17 from 20 leaves us 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.

Moving on to step 10:
17 can be fit into 30 1 times, resulting in a remainder of 13.
The next digit of our result is 1. 
Result so far: 28872.9411
If we subtract 17 from 30, we 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 28872.9411 with a remaining 0.00013.
