We look at the division of 311539 by 31 
Let's see how many times 31 fits into 311539.

Advancing to step 1:
When dividing 3 by 31, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 31

Going ahead to step 2:
When dividing 31 by 31, we get 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 31 from 31 and we're left with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 31

Going ahead to step 3:
31 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 31

Let's proceed to step 4:
15 divided by 31 is 0 with a remainder of 15.
The next digit of our result is 0. 
Result so far: 100.0
Subtracting 0 from 15 leaves us with 15.
Append the next digit (3) from the dividend to 15 and continue with: 153 / 31

Advancing to step 5:
31 goes into 153 4 times with a remainder of 29.
Use 4 as the next digit of our solution. 
Result so far: 1004.0
The remainder is 29 after subtracting 124 from 153.
Include the next digit (9) from the dividend after 29, then repeat: 299 / 31

Advancing to step 6:
When dividing 299 by 31, we get 9 with a remainder of 20.
Record the quotient 9 as the next digit in the result. 
Result so far: 10049.0
Subtract 279 from 299 to 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.

Let's proceed to step 7:
The number 31 fits into 200 6 times, leaving a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 10049.6
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.

Advancing to step 8:
31 goes into 140 4 times with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 10049.64
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.

Going ahead to step 9:
31 can be fit into 160 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 10049.645
Subtract 155 from 160 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 10:
31 can be fit into 50 1 times, resulting in a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 10049.6451
If we take 31 away from 50, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 11:
31 goes into 190 6 times with a remainder of 4.
The next digit of our result is 6. 
Result so far: 10049.64516
If we subtract 186 from 190, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 12:
40 divided by 31 is 1 with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 10049.645161
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.

Step 13:
90 divided by 31 is 2 with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 10049.6451612
If we subtract 62 from 90, we get 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 14:
When dividing 280 by 31, we get 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 10049.64516129
Subtracting 279 from 280 leaves us 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.

In conclusion, the division gives 10049.64516129 with a balance of 1e-09.
