We look at the division of 343660 by 31 
We want to figure out the number of times 343660 can be divided by 31.

Advancing to step 1:
3 divided by 31 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 31

Advancing to step 2:
The number 31 fits into 34 1 times, leaving a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 3 after subtracting 31 from 34.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 31

Let's proceed to step 3:
The number 31 fits into 33 1 times, leaving a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we take 31 away from 33, we end up with 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 31

Moving on to step 4:
31 goes into 26 0 times with a remainder of 26.
The number 0 becomes the next digit in our result. 
Result so far: 110.0
If we take 0 away from 26, we end up with 26.
Grab the next digit (6) from the dividend, add it to 26, then carry on: 266 / 31

On to step 5:
31 can be fit into 266 8 times, resulting in a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 1108.0
Subtract 248 from 266 to get 18.
Fetch the next digit (0) from the dividend, attach it to 18 and continue: 180 / 31

On to step 6:
If we divide 180 by 31, we get 5 and a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 11085.0
Subtracting 155 from 180 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 7:
31 can be fit into 250 8 times, resulting in a remainder of 2.
The next digit of our result is 8. 
Result so far: 11085.8
Subtracting 248 from 250 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
31 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 11085.8
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
If we divide 200 by 31, we get 6 and a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 11085.806
Deduct 186 from 200 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 10:
31 goes into 140 4 times with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 11085.8064
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.

Advancing to step 11:
When dividing 160 by 31, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 11085.80645
If we take 155 away from 160, we end up with 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 12:
The number 31 fits into 50 1 times, leaving a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 11085.806451
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.

Let's proceed to step 13:
31 can be fit into 190 6 times, resulting in a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 11085.8064516
Subtracting 186 from 190 leaves us with 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 14:
31 goes into 40 1 times with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 11085.80645161
Subtracting 31 from 40 leaves us 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.

In conclusion, the division gives 11085.80645161 with a balance of 9e-09.
