We look at the division of 17009987 by 556 
We're looking to find how many times 556 goes into 17009987.

On to step 1:
556 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 556

Step 2:
556 goes into 17 0 times with a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Include the next digit (0) from the dividend after 17, then repeat: 170 / 556

Advancing to step 3:
170 divided by 556 is 0 with a remainder of 170.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 170 and we're left with 170.
Include the next digit (0) from the dividend after 170, then repeat: 1700 / 556

Step 4:
The number 556 fits into 1700 3 times, leaving a remainder of 32.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 32 after subtracting 1668 from 1700.
Fetch the next digit (9) from the dividend, attach it to 32 and continue: 329 / 556

Step 5:
329 divided by 556 is 0 with a remainder of 329.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
Deduct 0 from 329 and we're left with 329.
Include the next digit (9) from the dividend after 329, then repeat: 3299 / 556

Step 6:
556 goes into 3299 5 times with a remainder of 519.
Put 5 as the next digit of the answer. 
Result so far: 305.0
The remainder is 519 after subtracting 2780 from 3299.
Grab the next digit (8) from the dividend, add it to 519, then carry on: 5198 / 556

On to step 7:
If we divide 5198 by 556, we get 9 and a remainder of 194.
Use 9 as the next digit of our solution. 
Result so far: 3059.0
If we subtract 5004 from 5198, we get 194.
Take the next digit (7) from the dividend and append it to 194, then repeat: 1947 / 556

Going ahead to step 8:
1947 divided by 556 is 3 with a remainder of 279.
The next digit of our result is 3. 
Result so far: 30593.0
The remainder is 279 after subtracting 1668 from 1947.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Moving on to step 9:
The number 556 fits into 2790 5 times, leaving a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 30593.5
Deduct 2780 from 2790 and we're left 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.

Let's proceed to step 10:
If we divide 100 by 556, we get 0 and a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 30593.5
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 11:
556 can be fit into 1000 1 times, resulting in a remainder of 444.
Use 1 as the next digit of our solution. 
Result so far: 30593.501
Subtract 556 from 1000 to get 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

On to step 12:
4440 divided by 556 is 7 with a remainder of 548.
Record the quotient 7 as the next digit in the result. 
Result so far: 30593.5017
If we take 3892 away from 4440, we end up with 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Going ahead to step 13:
If we divide 5480 by 556, we get 9 and a remainder of 476.
Put 9 as the next digit of the answer. 
Result so far: 30593.50179
Deduct 5004 from 5480 and we're left with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Moving on to step 14:
When dividing 4760 by 556, we get 8 with a remainder of 312.
Write down 8 as next digit of the result. 
Result so far: 30593.501798
If we subtract 4448 from 4760, we get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Going ahead to step 15:
The number 556 fits into 3120 5 times, leaving a remainder of 340.
Put 5 as the next digit of the answer. 
Result so far: 30593.5017985
Deduct 2780 from 3120 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Going ahead to step 16:
The number 556 fits into 3400 6 times, leaving a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 30593.50179856
Subtract 3336 from 3400 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

After the division, we end up with 30593.50179856 and a remainder of 6.4e-08.
