850395 ÷ 31 
We're looking to find how many times 31 goes into 850395.

Advancing to step 1:
8 divided by 31 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 31

Advancing to step 2:
31 can be fit into 85 2 times, resulting in a remainder of 23.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 62 away from 85, we end up with 23.
Grab the next digit (0) from the dividend, add it to 23, then carry on: 230 / 31

Step 3:
If we divide 230 by 31, we get 7 and a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
Subtract 217 from 230 to get 13.
Bring next digit (3) of the dividend behind the 13 and repeat the process: 133 / 31

Going ahead to step 4:
133 divided by 31 is 4 with a remainder of 9.
Write down 4 as next digit of the result. 
Result so far: 274.0
Subtract 124 from 133 to get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 31

Moving on to step 5:
When dividing 99 by 31, we get 3 with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 2743.0
Subtracting 93 from 99 leaves us with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 31

Step 6:
31 can be fit into 65 2 times, resulting in a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 27432.0
Subtracting 62 from 65 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
30 divided by 31 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 27432.0
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
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: 27432.09
Deduct 279 from 300 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 9:
If we divide 210 by 31, we get 6 and a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 27432.096
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.

Moving on to step 10:
31 can be fit into 240 7 times, resulting in a remainder of 23.
The next digit of our result is 7. 
Result so far: 27432.0967
If we subtract 217 from 240, we 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.

On to step 11:
If we divide 230 by 31, we get 7 and a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 27432.09677
Subtract 217 from 230 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final result is 27432.09677 with a remainder of 1.3e-05.
