We look at the division of 343983 by 13 
Our goal is to divide 343983 by 13.

Let's proceed to step 1:
13 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 13

Moving on to step 2:
34 divided by 13 is 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 8 after subtracting 26 from 34.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 13

On to step 3:
The number 13 fits into 83 6 times, leaving a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 26.0
Subtract 78 from 83 to get 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 13

Let's proceed to step 4:
If we divide 59 by 13, we get 4 and a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 264.0
The remainder is 7 after subtracting 52 from 59.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 13

Going ahead to step 5:
13 can be fit into 78 6 times, resulting in a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 2646.0
Subtracting 78 from 78 leaves us with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 13

Advancing to step 6:
13 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 26460.0
The remainder is 3 after subtracting 0 from 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
13 can be fit into 30 2 times, resulting in a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 26460.2
The remainder is 4 after subtracting 26 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
40 divided by 13 is 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 26460.23
If we take 39 away from 40, we end up 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:
When dividing 10 by 13, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 26460.23
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
13 can be fit into 100 7 times, resulting in a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 26460.2307
If we take 91 away from 100, we end up 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.

Going ahead to step 11:
13 can be fit into 90 6 times, resulting in a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 26460.23076
Subtracting 78 from 90 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 12:
120 divided by 13 is 9 with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 26460.230769
The remainder is 3 after subtracting 117 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 13:
The number 13 fits into 30 2 times, leaving a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 26460.2307692
If we subtract 26 from 30, 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.

Going ahead to step 14:
13 goes into 40 3 times with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 26460.23076923
If we subtract 39 from 40, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

After the division, we end up with 26460.23076923 and a remainder of 1e-09.
