648572 divided by 31 
We want to divide 648572 by 31.

Let's proceed to step 1:
31 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 31

Step 2:
The number 31 fits into 64 2 times, leaving a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 2 after subtracting 62 from 64.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 31

Let's proceed to step 3:
31 can be fit into 28 0 times, resulting in a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 20.0
If we take 0 away from 28, we end up with 28.
Grab the next digit (5) from the dividend, add it to 28, then carry on: 285 / 31

Step 4:
The number 31 fits into 285 9 times, leaving a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 209.0
Subtracting 279 from 285 leaves us with 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 31

Going ahead to step 5:
The number 31 fits into 67 2 times, leaving a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 2092.0
Subtract 62 from 67 to get 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 31

Going ahead to step 6:
The number 31 fits into 52 1 times, leaving a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 20921.0
The remainder is 21 after subtracting 31 from 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 7:
The number 31 fits into 210 6 times, leaving a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 20921.6
Subtract 186 from 210 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 8:
31 goes into 240 7 times with a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 20921.67
Subtract 217 from 240 to 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.

Moving on to step 9:
If we divide 230 by 31, we get 7 and a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 20921.677
Deduct 217 from 230 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final result is 20921.677 with a remainder of 0.0013.
