We look at the division of 828639 by 31 
Let's see how many times 31 fits into 828639.

Step 1:
When dividing 8 by 31, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 31

Going ahead to step 2:
82 divided by 31 is 2 with a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 62 from 82 to get 20.
Append the next digit (8) from the dividend to 20 and continue with: 208 / 31

On to step 3:
31 goes into 208 6 times with a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 26.0
The remainder is 22 after subtracting 186 from 208.
Take the next digit (6) from the dividend and append it to 22, then repeat: 226 / 31

Advancing to step 4:
226 divided by 31 is 7 with a remainder of 9.
The next digit of our result is 7. 
Result so far: 267.0
If we subtract 217 from 226, we get 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 31

Going ahead to step 5:
31 can be fit into 93 3 times, resulting in a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 2673.0
Subtract 93 from 93 to get 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 31

Moving on to step 6:
When dividing 9 by 31, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 26730.0
If we take 0 away from 9, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
If we divide 90 by 31, we get 2 and a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 26730.2
If we subtract 62 from 90, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 8:
The number 31 fits into 280 9 times, leaving a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 26730.29
Deduct 279 from 280 and we're left 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.

Let's proceed to step 9:
10 divided by 31 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 26730.29
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 10:
When dividing 100 by 31, we get 3 with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 26730.2903
Subtract 93 from 100 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 11:
31 can be fit into 70 2 times, resulting in a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 26730.29032
Subtracting 62 from 70 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 12:
80 divided by 31 is 2 with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 26730.290322
The remainder is 18 after subtracting 62 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

After the division, we end up with 26730.290322 and a remainder of 1.8e-06.
