We're dividing 490862 by 31 
We want to divide 490862 by 31.

Going ahead to 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
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 31

Let's proceed to step 2:
If we divide 49 by 31, we get 1 and a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 31 from 49 leaves us with 18.
Fetch the next digit (0) from the dividend, attach it to 18 and continue: 180 / 31

Moving on to step 3:
31 goes into 180 5 times with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 15.0
The remainder is 25 after subtracting 155 from 180.
Bring next digit (8) of the dividend behind the 25 and repeat the process: 258 / 31

Advancing to step 4:
31 can be fit into 258 8 times, resulting in a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 158.0
The remainder is 10 after subtracting 248 from 258.
Include the next digit (6) from the dividend after 10, then repeat: 106 / 31

Let's proceed to step 5:
31 goes into 106 3 times with a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 1583.0
Subtract 93 from 106 to get 13.
Grab the next digit (2) from the dividend, add it to 13, then carry on: 132 / 31

Going ahead to step 6:
If we divide 132 by 31, we get 4 and a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 15834.0
Subtracting 124 from 132 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 7:
80 divided by 31 is 2 with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 15834.2
If we take 62 away from 80, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 8:
31 can be fit into 180 5 times, resulting in a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 15834.25
The remainder is 25 after subtracting 155 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 9:
31 can be fit into 250 8 times, resulting in a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 15834.258
Deduct 248 from 250 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 10:
31 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 15834.258
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 11:
When dividing 200 by 31, we get 6 with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 15834.25806
The remainder is 14 after subtracting 186 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 12:
31 goes into 140 4 times with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 15834.258064
If we take 124 away from 140, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 13:
When dividing 160 by 31, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 15834.2580645
Deduct 155 from 160 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 14:
50 divided by 31 is 1 with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 15834.25806451
Subtract 31 from 50 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The final outcome is 15834.25806451, with a leftover of 1.9e-08.
