We look at the division of 521305 by 31 
We're looking to find how many times 31 goes into 521305.

Going ahead to step 1:
31 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 31

Going ahead to step 2:
31 goes into 52 1 times with a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 31 away from 52, we end up with 21.
Bring next digit (1) of the dividend behind the 21 and repeat the process: 211 / 31

Going ahead to step 3:
If we divide 211 by 31, we get 6 and a remainder of 25.
Write down 6 as next digit of the result. 
Result so far: 16.0
The remainder is 25 after subtracting 186 from 211.
Fetch the next digit (3) from the dividend, attach it to 25 and continue: 253 / 31

Step 4:
31 can be fit into 253 8 times, resulting in a remainder of 5.
Put 8 as the next digit of the answer. 
Result so far: 168.0
If we subtract 248 from 253, we get 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 31

Let's proceed to step 5:
50 divided by 31 is 1 with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 1681.0
Subtract 31 from 50 to get 19.
Grab the next digit (5) from the dividend, add it to 19, then carry on: 195 / 31

On to step 6:
If we divide 195 by 31, we get 6 and a remainder of 9.
The next digit of our result is 6. 
Result so far: 16816.0
The remainder is 9 after subtracting 186 from 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
31 goes into 90 2 times with a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 16816.2
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.

Let's proceed to step 8:
31 can be fit into 280 9 times, resulting in a remainder of 1.
The next digit of our result is 9. 
Result so far: 16816.29
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 9:
31 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 16816.29
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 10:
100 divided by 31 is 3 with a remainder of 7.
The next digit of our result is 3. 
Result so far: 16816.2903
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 11:
If we divide 70 by 31, we get 2 and a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 16816.29032
If we take 62 away from 70, we end up 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.

Advancing to step 12:
31 can be fit into 80 2 times, resulting in a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 16816.290322
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.

In conclusion, the division gives 16816.290322 with a balance of 1.8e-06.
