We're dividing 571687 by 3 
Let's see how many times 3 fits into 571687.

Step 1:
When dividing 5 by 3, we get 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 2 after subtracting 3 from 5.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 3

Advancing to step 2:
27 divided by 3 is 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 19.0
If we subtract 27 from 27, we get 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 3

Going ahead to step 3:
If we divide 1 by 3, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 190.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 3

Step 4:
If we divide 16 by 3, we get 5 and a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 1905.0
The remainder is 1 after subtracting 15 from 16.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 3

Moving on to step 5:
18 divided by 3 is 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 19056.0
Subtract 18 from 18 to get 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 3

Moving on to step 6:
The number 3 fits into 7 2 times, leaving a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 190562.0
If we subtract 6 from 7, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
3 goes into 10 3 times with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 190562.3
Subtracting 9 from 10 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.

Advancing to step 8:
3 goes into 10 3 times with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 190562.33
If we take 9 away from 10, we end up 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.

After the division, we end up with 190562.33 and a remainder of 0.001.
