311440 divided by 31 
Our goal is to divide 311440 by 31.

On to step 1:
3 divided by 31 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 31

On to step 2:
The number 31 fits into 31 1 times, leaving a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 31 from 31 to get 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 31

On to step 3:
31 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 1, we end up with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 31

Let's proceed to step 4:
The number 31 fits into 14 0 times, leaving a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 100.0
The remainder is 14 after subtracting 0 from 14.
Include the next digit (4) from the dividend after 14, then repeat: 144 / 31

Step 5:
The number 31 fits into 144 4 times, leaving a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 1004.0
The remainder is 20 after subtracting 124 from 144.
Fetch the next digit (0) from the dividend, attach it to 20 and continue: 200 / 31

Step 6:
31 can be fit into 200 6 times, resulting in a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 10046.0
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.

On to step 7:
31 can be fit into 140 4 times, resulting in a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 10046.4
If we subtract 124 from 140, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 8:
31 can be fit into 160 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 10046.45
If we subtract 155 from 160, we 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.

Step 9:
When dividing 50 by 31, we get 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 10046.451
The remainder is 19 after subtracting 31 from 50.
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 10:
31 can be fit into 190 6 times, resulting in a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 10046.4516
Subtract 186 from 190 to 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 11:
31 can be fit into 40 1 times, resulting in a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 10046.45161
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.

Advancing to step 12:
31 goes into 90 2 times with a remainder of 28.
The next digit of our result is 2. 
Result so far: 10046.451612
The remainder is 28 after subtracting 62 from 90.
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 13:
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: 10046.4516129
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.

On to step 14:
When dividing 10 by 31, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 10046.4516129
Deduct 0 from 10 and we're left 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.

The final result is 10046.4516129 with a remainder of 1e-08.
