879649 ÷ 31 
Let's see how many times 31 fits into 879649.

Going ahead to step 1:
8 divided by 31 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 31

On to step 2:
31 can be fit into 87 2 times, resulting in a remainder of 25.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 62 from 87 and we're left with 25.
Fetch the next digit (9) from the dividend, attach it to 25 and continue: 259 / 31

Going ahead to step 3:
The number 31 fits into 259 8 times, leaving a remainder of 11.
Put 8 as the next digit of the answer. 
Result so far: 28.0
Subtracting 248 from 259 leaves us with 11.
Append the next digit (6) from the dividend to 11 and continue with: 116 / 31

On to step 4:
If we divide 116 by 31, we get 3 and a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 283.0
Subtracting 93 from 116 leaves us with 23.
Fetch the next digit (4) from the dividend, attach it to 23 and continue: 234 / 31

Moving on to step 5:
31 can be fit into 234 7 times, resulting in a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 2837.0
If we subtract 217 from 234, we get 17.
Include the next digit (9) from the dividend after 17, then repeat: 179 / 31

On to step 6:
When dividing 179 by 31, we get 5 with a remainder of 24.
Record the quotient 5 as the next digit in the result. 
Result so far: 28375.0
Subtract 155 from 179 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.

On to step 7:
31 goes into 240 7 times with a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 28375.7
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.

Going ahead to step 8:
When dividing 230 by 31, we get 7 with a remainder of 13.
The next digit of our result is 7. 
Result so far: 28375.77
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.

In conclusion, the division gives 28375.77 with a balance of 0.013.
