858834 divided by 31 
We want to figure out the number of times 858834 can be divided by 31.

Let's proceed to step 1:
8 divided by 31 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 31

Going ahead to step 2:
31 goes into 85 2 times with a remainder of 23.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 23 after subtracting 62 from 85.
Grab the next digit (8) from the dividend, add it to 23, then carry on: 238 / 31

Let's proceed to step 3:
When dividing 238 by 31, we get 7 with a remainder of 21.
The next digit of our result is 7. 
Result so far: 27.0
Subtracting 217 from 238 leaves us with 21.
Bring next digit (8) of the dividend behind the 21 and repeat the process: 218 / 31

Step 4:
31 goes into 218 7 times with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 277.0
Subtract 217 from 218 to get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 31

Going ahead to step 5:
If we divide 13 by 31, we get 0 and a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 2770.0
If we subtract 0 from 13, we get 13.
Append the next digit (4) from the dividend to 13 and continue with: 134 / 31

Going ahead to step 6:
134 divided by 31 is 4 with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 27704.0
The remainder is 10 after subtracting 124 from 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 7:
If we divide 100 by 31, we get 3 and a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 27704.3
If we take 93 away from 100, we end up with 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 8:
When dividing 70 by 31, we get 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 27704.32
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.

Step 9:
When dividing 80 by 31, we get 2 with a remainder of 18.
The next digit of our result is 2. 
Result so far: 27704.322
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.

The final outcome is 27704.322, with a leftover of 0.0018.
