We look at the division of 255720 by 17 
We want to divide 255720 by 17.

Let's proceed to step 1:
2 divided by 17 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 17

Moving on to step 2:
When dividing 25 by 17, we get 1 with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 17 from 25 leaves us with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 17

Step 3:
85 divided by 17 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Deduct 85 from 85 and we're left with 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 17

Let's proceed to step 4:
17 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 150.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 17

Let's proceed to step 5:
When dividing 72 by 17, we get 4 with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 1504.0
The remainder is 4 after subtracting 68 from 72.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 17

On to step 6:
The number 17 fits into 40 2 times, leaving a remainder of 6.
The next digit of our result is 2. 
Result so far: 15042.0
If we subtract 34 from 40, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
17 goes into 60 3 times with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 15042.3
The remainder is 9 after subtracting 51 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 8:
17 can be fit into 90 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 15042.35
Subtract 85 from 90 to 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.

Moving on to step 9:
17 can be fit into 50 2 times, resulting in a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 15042.352
If we subtract 34 from 50, we 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.

Moving on to step 10:
17 goes into 160 9 times with a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 15042.3529
Subtract 153 from 160 to get 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 11:
17 can be fit into 70 4 times, resulting in a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 15042.35294
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.

Let's proceed to step 12:
17 goes into 20 1 times with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 15042.352941
The remainder is 3 after subtracting 17 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 13:
30 divided by 17 is 1 with a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 15042.3529411
If we take 17 away from 30, we end up 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 15042.3529411 with a remainder of 1.3e-07.
