Let's divide 858008 by 31
We're looking to find how many times 31 goes into 858008.

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
Subtract 0 from 8 to get 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 31

Advancing to step 2:
31 goes into 85 2 times with a remainder of 23.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 62 from 85, we get 23.
Bring next digit (8) of the dividend behind the 23 and repeat the process: 238 / 31

Advancing to step 3:
238 divided by 31 is 7 with a remainder of 21.
The next digit of our result is 7. 
Result so far: 27.0
The remainder is 21 after subtracting 217 from 238.
Grab the next digit (0) from the dividend, add it to 21, then carry on: 210 / 31

Let's proceed to step 4:
When dividing 210 by 31, we get 6 with a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 276.0
Subtract 186 from 210 to get 24.
Grab the next digit (0) from the dividend, add it to 24, then carry on: 240 / 31

Moving on to step 5:
240 divided by 31 is 7 with a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 2767.0
If we take 217 away from 240, we end up with 23.
Bring next digit (8) of the dividend behind the 23 and repeat the process: 238 / 31

Moving on to step 6:
238 divided by 31 is 7 with a remainder of 21.
Put 7 as the next digit of the answer. 
Result so far: 27677.0
The remainder is 21 after subtracting 217 from 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 7:
When dividing 210 by 31, we get 6 with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 27677.6
If we take 186 away from 210, we end up with 24.
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 8:
240 divided by 31 is 7 with a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 27677.67
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.

Moving on to step 9:
31 can be fit into 230 7 times, resulting in a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 27677.677
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.

After the division, we end up with 27677.677 and a remainder of 0.0013.
