490424 ÷ 31 
We want to figure out the number of times 490424 can be divided by 31.

On to step 1:
If we divide 4 by 31, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 31

Going ahead to step 2:
If we divide 49 by 31, we get 1 and a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 31 from 49 to get 18.
Take the next digit (0) from the dividend and append it to 18, then repeat: 180 / 31

Going ahead to step 3:
180 divided by 31 is 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we take 155 away from 180, we end up with 25.
Include the next digit (4) from the dividend after 25, then repeat: 254 / 31

Moving on to step 4:
31 can be fit into 254 8 times, resulting in a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 158.0
If we subtract 248 from 254, we get 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 31

Step 5:
31 can be fit into 62 2 times, resulting in a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 1582.0
Subtracting 62 from 62 leaves us with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 31

Let's proceed to step 6:
31 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 15820.0
If we take 0 away from 4, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
If we divide 40 by 31, we get 1 and a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 15820.1
If we subtract 31 from 40, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 8:
90 divided by 31 is 2 with a remainder of 28.
The next digit of our result is 2. 
Result so far: 15820.12
Deduct 62 from 90 and we're left 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.

On to step 9:
280 divided by 31 is 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 15820.129
Deduct 279 from 280 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 10:
If we divide 10 by 31, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 15820.129
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.

Let's proceed to step 11:
The number 31 fits into 100 3 times, leaving a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 15820.12903
Subtracting 93 from 100 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 12:
31 can be fit into 70 2 times, resulting in a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 15820.129032
Subtracting 62 from 70 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 13:
31 can be fit into 80 2 times, resulting in a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 15820.1290322
Subtract 62 from 80 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

In conclusion, the division gives 15820.1290322 with a balance of 1.8e-07.
