490783 divided by 31 
Let's see how many times 31 fits into 490783.

Step 1:
The number 31 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 31

On to step 2:
The number 31 fits into 49 1 times, leaving a remainder of 18.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 31 from 49 to get 18.
Grab the next digit (0) from the dividend, add it to 18, then carry on: 180 / 31

On to step 3:
When dividing 180 by 31, we get 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we subtract 155 from 180, we get 25.
Append the next digit (7) from the dividend to 25 and continue with: 257 / 31

Let's proceed to step 4:
257 divided by 31 is 8 with a remainder of 9.
The next digit of our result is 8. 
Result so far: 158.0
Subtract 248 from 257 to get 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 31

Going ahead to step 5:
31 goes into 98 3 times with a remainder of 5.
The next digit of our result is 3. 
Result so far: 1583.0
If we take 93 away from 98, we end up with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 31

Step 6:
31 goes into 53 1 times with a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 15831.0
The remainder is 22 after subtracting 31 from 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 7:
220 divided by 31 is 7 with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 15831.7
Subtract 217 from 220 to get 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 8:
30 divided by 31 is 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 15831.7
Subtract 0 from 30 to 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.

Advancing to step 9:
The number 31 fits into 300 9 times, leaving a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 15831.709
Subtracting 279 from 300 leaves us 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.

Step 10:
When dividing 210 by 31, we get 6 with a remainder of 24.
The next digit of our result is 6. 
Result so far: 15831.7096
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 11:
31 can be fit into 240 7 times, resulting in a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 15831.70967
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.

Step 12:
If we divide 230 by 31, we get 7 and a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 15831.709677
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.

In conclusion, the division gives 15831.709677 with a balance of 1.3e-06.
