680510 divided by 31 
We want to divide 680510 by 31.

On to step 1:
6 divided by 31 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 31

Going ahead to step 2:
68 divided by 31 is 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 62 from 68 to get 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 31

Advancing to step 3:
31 goes into 60 1 times with a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
The remainder is 29 after subtracting 31 from 60.
Bring next digit (5) of the dividend behind the 29 and repeat the process: 295 / 31

Step 4:
The number 31 fits into 295 9 times, leaving a remainder of 16.
The next digit of our result is 9. 
Result so far: 219.0
If we take 279 away from 295, we end up with 16.
Append the next digit (1) from the dividend to 16 and continue with: 161 / 31

Going ahead to step 5:
If we divide 161 by 31, we get 5 and a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 2195.0
Subtract 155 from 161 to get 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 31

Step 6:
If we divide 60 by 31, we get 1 and a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 21951.0
Subtracting 31 from 60 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 7:
The number 31 fits into 290 9 times, leaving a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 21951.9
Subtracting 279 from 290 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 8:
110 divided by 31 is 3 with a remainder of 17.
The next digit of our result is 3. 
Result so far: 21951.93
If we subtract 93 from 110, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 9:
170 divided by 31 is 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 21951.935
Deduct 155 from 170 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 10:
If we divide 150 by 31, we get 4 and a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 21951.9354
Subtract 124 from 150 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 11:
31 goes into 260 8 times with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 21951.93548
The remainder is 12 after subtracting 248 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 12:
31 can be fit into 120 3 times, resulting in a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 21951.935483
If we subtract 93 from 120, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 13:
If we divide 270 by 31, we get 8 and a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 21951.9354838
If we subtract 248 from 270, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 14:
The number 31 fits into 220 7 times, leaving a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 21951.93548387
Subtract 217 from 220 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The quotient of the division is 21951.93548387, and the remainder is 3e-09.
