We're dividing 858358 by 31 
Our goal is to divide 858358 by 31.

Moving on to step 1:
31 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 31

Moving on to step 2:
The number 31 fits into 85 2 times, leaving a remainder of 23.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 62 away from 85, we end up with 23.
Append the next digit (8) from the dividend to 23 and continue with: 238 / 31

On to step 3:
If we divide 238 by 31, we get 7 and a remainder of 21.
The next digit of our result is 7. 
Result so far: 27.0
Deduct 217 from 238 and we're left with 21.
Grab the next digit (3) from the dividend, add it to 21, then carry on: 213 / 31

Step 4:
When dividing 213 by 31, we get 6 with a remainder of 27.
The next digit of our result is 6. 
Result so far: 276.0
If we subtract 186 from 213, we get 27.
Append the next digit (5) from the dividend to 27 and continue with: 275 / 31

Let's proceed to step 5:
31 goes into 275 8 times with a remainder of 27.
The next digit of our result is 8. 
Result so far: 2768.0
The remainder is 27 after subtracting 248 from 275.
Append the next digit (8) from the dividend to 27 and continue with: 278 / 31

Step 6:
If we divide 278 by 31, we get 8 and a remainder of 30.
Write down 8 as next digit of the result. 
Result so far: 27688.0
If we subtract 248 from 278, we get 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:
If we divide 300 by 31, we get 9 and a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 27688.9
If we subtract 279 from 300, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 8:
210 divided by 31 is 6 with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 27688.96
Deduct 186 from 210 and we're left 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.

Advancing to step 9:
When dividing 240 by 31, we get 7 with a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 27688.967
Subtracting 217 from 240 leaves us 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.

Advancing to step 10:
31 goes into 230 7 times with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 27688.9677
Subtracting 217 from 230 leaves us 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 27688.9677 and a remainder of 0.00013.
