We're dividing 571671 by 18 
We want to figure out the number of times 571671 can be divided by 18.

On to step 1:
5 divided by 18 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 18

Step 2:
18 can be fit into 57 3 times, resulting in a remainder of 3.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 54 from 57 leaves us with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 18

Let's proceed to step 3:
18 can be fit into 31 1 times, resulting in a remainder of 13.
The next digit of our result is 1. 
Result so far: 31.0
Subtract 18 from 31 to get 13.
Include the next digit (6) from the dividend after 13, then repeat: 136 / 18

On to step 4:
18 goes into 136 7 times with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 317.0
Subtracting 126 from 136 leaves us with 10.
Take the next digit (7) from the dividend and append it to 10, then repeat: 107 / 18

Going ahead to step 5:
The number 18 fits into 107 5 times, leaving a remainder of 17.
Write down 5 as next digit of the result. 
Result so far: 3175.0
Subtracting 90 from 107 leaves us with 17.
Take the next digit (1) from the dividend and append it to 17, then repeat: 171 / 18

Going ahead to step 6:
The number 18 fits into 171 9 times, leaving a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 31759.0
If we take 162 away from 171, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
The number 18 fits into 90 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 31759.5
Subtract 90 from 90 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
18 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 31759.5
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
The number 18 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 31759.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 31759.5, with a leftover of 0.0.
