We divide 660417 by 31
We're looking to find how many times 31 goes into 660417.

Going ahead to step 1:
When dividing 6 by 31, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 31

On to step 2:
31 can be fit into 66 2 times, resulting in a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 4 after subtracting 62 from 66.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 31

Going ahead to step 3:
When dividing 40 by 31, we get 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 21.0
If we subtract 31 from 40, we get 9.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 31

Step 4:
31 goes into 94 3 times with a remainder of 1.
The next digit of our result is 3. 
Result so far: 213.0
If we subtract 93 from 94, we get 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 31

Going ahead to step 5:
The number 31 fits into 11 0 times, leaving a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 2130.0
The remainder is 11 after subtracting 0 from 11.
Bring next digit (7) of the dividend behind the 11 and repeat the process: 117 / 31

Step 6:
The number 31 fits into 117 3 times, leaving a remainder of 24.
Use 3 as the next digit of our solution. 
Result so far: 21303.0
Subtracting 93 from 117 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 7:
31 can be fit into 240 7 times, resulting in a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 21303.7
If we subtract 217 from 240, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 8:
The number 31 fits into 230 7 times, leaving a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 21303.77
The remainder is 13 after subtracting 217 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

After the division, we end up with 21303.77 and a remainder of 0.013.
