We divide 168243 by 13
Our goal is to divide 168243 by 13.

Advancing to step 1:
If we divide 1 by 13, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 13

Step 2:
If we divide 16 by 13, we get 1 and a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 13 from 16, we get 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 13

Going ahead to step 3:
The number 13 fits into 38 2 times, leaving a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 26 from 38 leaves us with 12.
Include the next digit (2) from the dividend after 12, then repeat: 122 / 13

Moving on to step 4:
The number 13 fits into 122 9 times, leaving a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 129.0
The remainder is 5 after subtracting 117 from 122.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 13

Moving on to step 5:
13 goes into 54 4 times with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 1294.0
If we subtract 52 from 54, we get 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 13

Advancing to step 6:
The number 13 fits into 23 1 times, leaving a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 12941.0
If we take 13 away from 23, we end up 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.

On to step 7:
13 can be fit into 100 7 times, resulting in a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 12941.7
Subtract 91 from 100 to 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 8:
90 divided by 13 is 6 with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 12941.76
The remainder is 12 after subtracting 78 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
If we divide 120 by 13, we get 9 and a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 12941.769
If we take 117 away from 120, we end up 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.

Going ahead to step 10:
13 goes into 30 2 times with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 12941.7692
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.

Going ahead to step 11:
If we divide 40 by 13, we get 3 and a remainder of 1.
The next digit of our result is 3. 
Result so far: 12941.76923
Deduct 39 from 40 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.

Step 12:
The number 13 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 12941.76923
The remainder is 10 after subtracting 0 from 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 13:
When dividing 100 by 13, we get 7 with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 12941.7692307
Subtracting 91 from 100 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.

Going ahead to step 14:
13 goes into 90 6 times with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 12941.76923076
If we subtract 78 from 90, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 12941.76923076, with a leftover of 1.2e-08.
