We're dividing 680728 by 31 
We're looking to find how many times 31 goes into 680728.

Going ahead to step 1:
If we divide 6 by 31, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 31

Let's proceed to step 2:
31 goes into 68 2 times with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 62 from 68 to get 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 31

Going ahead to step 3:
When dividing 60 by 31, we get 1 with a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 21.0
Subtracting 31 from 60 leaves us with 29.
Take the next digit (7) from the dividend and append it to 29, then repeat: 297 / 31

On to step 4:
31 goes into 297 9 times with a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 219.0
Subtracting 279 from 297 leaves us with 18.
Fetch the next digit (2) from the dividend, attach it to 18 and continue: 182 / 31

Let's proceed to step 5:
31 can be fit into 182 5 times, resulting in a remainder of 27.
Record the quotient 5 as the next digit in the result. 
Result so far: 2195.0
Subtract 155 from 182 to get 27.
Grab the next digit (8) from the dividend, add it to 27, then carry on: 278 / 31

On to step 6:
278 divided by 31 is 8 with a remainder of 30.
Put 8 as the next digit of the answer. 
Result so far: 21958.0
If we take 248 away from 278, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 7:
31 can be fit into 300 9 times, resulting in a remainder of 21.
The next digit of our result is 9. 
Result so far: 21958.9
The remainder is 21 after subtracting 279 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 8:
31 can be fit into 210 6 times, resulting in a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 21958.96
The remainder is 24 after subtracting 186 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 9:
31 can be fit into 240 7 times, resulting in a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 21958.967
If we take 217 away from 240, we end up with 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 10:
When dividing 230 by 31, we get 7 with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 21958.9677
If we take 217 away from 230, we end up 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 quotient of the division is 21958.9677, and the remainder is 0.00013.
