We look at the division of 390257 by 17 
We're looking to find how many times 17 goes into 390257.

Let's proceed to step 1:
17 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 17

On to step 2:
39 divided by 17 is 2 with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 5 after subtracting 34 from 39.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 17

Going ahead to step 3:
17 can be fit into 50 2 times, resulting in a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
If we subtract 34 from 50, we get 16.
Bring next digit (2) of the dividend behind the 16 and repeat the process: 162 / 17

Let's proceed to step 4:
If we divide 162 by 17, we get 9 and a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 229.0
If we subtract 153 from 162, we get 9.
Bring next digit (5) of the dividend behind the 9 and repeat the process: 95 / 17

Let's proceed to step 5:
95 divided by 17 is 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 2295.0
The remainder is 10 after subtracting 85 from 95.
Bring next digit (7) of the dividend behind the 10 and repeat the process: 107 / 17

Step 6:
17 goes into 107 6 times with a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 22956.0
If we take 102 away from 107, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
When dividing 50 by 17, we get 2 with a remainder of 16.
The next digit of our result is 2. 
Result so far: 22956.2
If we take 34 away from 50, we end up 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.

Step 8:
17 goes into 160 9 times with a remainder of 7.
The next digit of our result is 9. 
Result so far: 22956.29
If we take 153 away from 160, we end up 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.

Advancing to step 9:
The number 17 fits into 70 4 times, leaving a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 22956.294
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.

Moving on to step 10:
17 can be fit into 20 1 times, resulting in a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 22956.2941
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 11:
If we divide 30 by 17, we get 1 and a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 22956.29411
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.

In conclusion, the division gives 22956.29411 with a balance of 1.3e-05.
