549220 ÷ 31 
Let's see how many times 31 fits into 549220.

Step 1:
The number 31 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 31

Advancing to step 2:
31 can be fit into 54 1 times, resulting in a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 31 from 54 and we're left with 23.
Grab the next digit (9) from the dividend, add it to 23, then carry on: 239 / 31

Going ahead to step 3:
31 goes into 239 7 times with a remainder of 22.
Write down 7 as next digit of the result. 
Result so far: 17.0
If we subtract 217 from 239, we get 22.
Fetch the next digit (2) from the dividend, attach it to 22 and continue: 222 / 31

Let's proceed to step 4:
If we divide 222 by 31, we get 7 and a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 177.0
The remainder is 5 after subtracting 217 from 222.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 31

Step 5:
When dividing 52 by 31, we get 1 with a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 1771.0
The remainder is 21 after subtracting 31 from 52.
Include the next digit (0) from the dividend after 21, then repeat: 210 / 31

On to step 6:
31 goes into 210 6 times with a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 17716.0
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 7:
240 divided by 31 is 7 with a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 17716.7
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.

Step 8:
The number 31 fits into 230 7 times, leaving a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 17716.77
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.

After the division, we end up with 17716.77 and a remainder of 0.013.
