513224 ÷ 31 
Let's see how many times 31 fits into 513224.

Let's proceed to step 1:
5 divided by 31 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 31

Step 2:
31 can be fit into 51 1 times, resulting in a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 31 from 51, we get 20.
Bring next digit (3) of the dividend behind the 20 and repeat the process: 203 / 31

Step 3:
31 goes into 203 6 times with a remainder of 17.
Write down 6 as next digit of the result. 
Result so far: 16.0
Deduct 186 from 203 and we're left with 17.
Append the next digit (2) from the dividend to 17 and continue with: 172 / 31

Going ahead to step 4:
31 can be fit into 172 5 times, resulting in a remainder of 17.
Record the quotient 5 as the next digit in the result. 
Result so far: 165.0
Subtracting 155 from 172 leaves us with 17.
Append the next digit (2) from the dividend to 17 and continue with: 172 / 31

Advancing to step 5:
The number 31 fits into 172 5 times, leaving a remainder of 17.
Record the quotient 5 as the next digit in the result. 
Result so far: 1655.0
The remainder is 17 after subtracting 155 from 172.
Bring next digit (4) of the dividend behind the 17 and repeat the process: 174 / 31

Moving on to step 6:
The number 31 fits into 174 5 times, leaving a remainder of 19.
The number 5 becomes the next digit in our result. 
Result so far: 16555.0
If we subtract 155 from 174, we 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.

Let's proceed to step 7:
If we divide 190 by 31, we get 6 and a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 16555.6
The remainder is 4 after subtracting 186 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
The number 31 fits into 40 1 times, leaving a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 16555.61
Deduct 31 from 40 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 9:
31 goes into 90 2 times with a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 16555.612
Subtracting 62 from 90 leaves us 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.

Advancing to step 10:
The number 31 fits into 280 9 times, leaving a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 16555.6129
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.

Moving on to step 11:
31 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 16555.6129
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 12:
100 divided by 31 is 3 with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 16555.612903
Deduct 93 from 100 and we're left 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.

Advancing to step 13:
31 can be fit into 70 2 times, resulting in a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 16555.6129032
If we subtract 62 from 70, we 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.

On to step 14:
80 divided by 31 is 2 with a remainder of 18.
The next digit of our result is 2. 
Result so far: 16555.61290322
Subtracting 62 from 80 leaves us 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.

The final result is 16555.61290322 with a remainder of 1.8e-08.
