We divide 17172730 by 509
We want to divide 17172730 by 509.

Moving on to step 1:
If we divide 1 by 509, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 509

Going ahead to step 2:
17 divided by 509 is 0 with a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Append the next digit (1) from the dividend to 17 and continue with: 171 / 509

Advancing to step 3:
If we divide 171 by 509, we get 0 and a remainder of 171.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 171 after subtracting 0 from 171.
Append the next digit (7) from the dividend to 171 and continue with: 1717 / 509

Advancing to step 4:
When dividing 1717 by 509, we get 3 with a remainder of 190.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 1527 from 1717 to get 190.
Bring next digit (2) of the dividend behind the 190 and repeat the process: 1902 / 509

On to step 5:
When dividing 1902 by 509, we get 3 with a remainder of 375.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
If we subtract 1527 from 1902, we get 375.
Grab the next digit (7) from the dividend, add it to 375, then carry on: 3757 / 509

Let's proceed to step 6:
509 can be fit into 3757 7 times, resulting in a remainder of 194.
Put 7 as the next digit of the answer. 
Result so far: 337.0
If we subtract 3563 from 3757, we get 194.
Append the next digit (3) from the dividend to 194 and continue with: 1943 / 509

Let's proceed to step 7:
If we divide 1943 by 509, we get 3 and a remainder of 416.
Record the quotient 3 as the next digit in the result. 
Result so far: 3373.0
Deduct 1527 from 1943 and we're left with 416.
Append the next digit (0) from the dividend to 416 and continue with: 4160 / 509

Going ahead to step 8:
If we divide 4160 by 509, we get 8 and a remainder of 88.
Use 8 as the next digit of our solution. 
Result so far: 33738.0
If we take 4072 away from 4160, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 9:
The number 509 fits into 880 1 times, leaving a remainder of 371.
Record the quotient 1 as the next digit in the result. 
Result so far: 33738.1
If we subtract 509 from 880, we get 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Moving on to step 10:
509 goes into 3710 7 times with a remainder of 147.
The number 7 becomes the next digit in our result. 
Result so far: 33738.17
Subtracting 3563 from 3710 leaves us with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Step 11:
509 goes into 1470 2 times with a remainder of 452.
The next digit of our result is 2. 
Result so far: 33738.172
If we subtract 1018 from 1470, we get 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Let's proceed to step 12:
When dividing 4520 by 509, we get 8 with a remainder of 448.
The number 8 becomes the next digit in our result. 
Result so far: 33738.1728
Subtracting 4072 from 4520 leaves us with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

On to step 13:
509 can be fit into 4480 8 times, resulting in a remainder of 408.
Write down 8 as next digit of the result. 
Result so far: 33738.17288
If we take 4072 away from 4480, we end up with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Our division results in 33738.17288 with a remaining 0.000408.
