820357 divided by 31 
We want to figure out the number of times 820357 can be divided by 31.

Step 1:
If we divide 8 by 31, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 31

Step 2:
If we divide 82 by 31, we get 2 and a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 62 from 82 to get 20.
Include the next digit (0) from the dividend after 20, then repeat: 200 / 31

On to step 3:
If we divide 200 by 31, we get 6 and a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 26.0
Subtracting 186 from 200 leaves us with 14.
Fetch the next digit (3) from the dividend, attach it to 14 and continue: 143 / 31

Step 4:
31 can be fit into 143 4 times, resulting in a remainder of 19.
Use 4 as the next digit of our solution. 
Result so far: 264.0
If we take 124 away from 143, we end up with 19.
Bring next digit (5) of the dividend behind the 19 and repeat the process: 195 / 31

Moving on to step 5:
If we divide 195 by 31, we get 6 and a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 2646.0
Subtracting 186 from 195 leaves us with 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 31

Let's proceed to step 6:
When dividing 97 by 31, we get 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 26463.0
The remainder is 4 after subtracting 93 from 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
The number 31 fits into 40 1 times, leaving a remainder of 9.
The next digit of our result is 1. 
Result so far: 26463.1
The remainder is 9 after subtracting 31 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 8:
When dividing 90 by 31, we get 2 with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 26463.12
If we take 62 away from 90, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 9:
31 can be fit into 280 9 times, resulting in a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 26463.129
The remainder is 1 after subtracting 279 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 10:
31 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 26463.129
If we take 0 away from 10, we end up with 10.
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 11:
31 can be fit into 100 3 times, resulting in a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 26463.12903
If we subtract 93 from 100, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 12:
The number 31 fits into 70 2 times, leaving a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 26463.129032
Subtract 62 from 70 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 13:
31 goes into 80 2 times with a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 26463.1290322
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 result is 26463.1290322 with a remainder of 1.8e-07.
