We divide 257086 by 17
We're looking to find how many times 17 goes into 257086.

On to step 1:
2 divided by 17 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 17

Step 2:
If we divide 25 by 17, we get 1 and a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 17 from 25 to get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 17

Step 3:
When dividing 87 by 17, we get 5 with a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtract 85 from 87 to get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 17

On to step 4:
17 goes into 20 1 times with a remainder of 3.
The next digit of our result is 1. 
Result so far: 151.0
If we subtract 17 from 20, we get 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 17

Going ahead to step 5:
When dividing 38 by 17, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 1512.0
Subtract 34 from 38 to get 4.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 17

Going ahead to step 6:
The number 17 fits into 46 2 times, leaving a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 15122.0
Subtracting 34 from 46 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 7:
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: 15122.7
Subtracting 119 from 120 leaves us 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.

Moving on to step 8:
The number 17 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 15122.7
Subtracting 0 from 10 leaves us with 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 9:
The number 17 fits into 100 5 times, leaving a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 15122.705
Deduct 85 from 100 and we're left 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.

Let's proceed to step 10:
If we divide 150 by 17, we get 8 and a remainder of 14.
The next digit of our result is 8. 
Result so far: 15122.7058
Subtracting 136 from 150 leaves us 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.

Let's proceed to step 11:
17 can be fit into 140 8 times, resulting in a remainder of 4.
The next digit of our result is 8. 
Result so far: 15122.70588
The remainder is 4 after subtracting 136 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 15122.70588 with a balance of 4e-06.
