We're dividing 343886 by 31 
We want to divide 343886 by 31.

On to step 1:
If we divide 3 by 31, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 31

Advancing to step 2:
If we divide 34 by 31, we get 1 and a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 31 from 34 leaves us with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 31

Moving on to step 3:
31 can be fit into 33 1 times, resulting in a remainder of 2.
The next digit of our result is 1. 
Result so far: 11.0
If we subtract 31 from 33, we get 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 31

Step 4:
The number 31 fits into 28 0 times, leaving a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 110.0
The remainder is 28 after subtracting 0 from 28.
Include the next digit (8) from the dividend after 28, then repeat: 288 / 31

Step 5:
The number 31 fits into 288 9 times, leaving a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 1109.0
If we subtract 279 from 288, we get 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 31

Moving on to step 6:
31 can be fit into 96 3 times, resulting in a remainder of 3.
The next digit of our result is 3. 
Result so far: 11093.0
Deduct 93 from 96 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
When dividing 30 by 31, we get 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 11093.0
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
300 divided by 31 is 9 with a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 11093.09
Deduct 279 from 300 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 9:
The number 31 fits into 210 6 times, leaving a remainder of 24.
The next digit of our result is 6. 
Result so far: 11093.096
The remainder is 24 after subtracting 186 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 10:
31 can be fit into 240 7 times, resulting in a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 11093.0967
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.

Going ahead to step 11:
31 can be fit into 230 7 times, resulting in a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 11093.09677
If we take 217 away from 230, we end up 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.

The quotient of the division is 11093.09677, and the remainder is 1.3e-05.
