We look at the division of 239989 by 13 
We're looking to find how many times 13 goes into 239989.

On to step 1:
13 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 13

Step 2:
13 can be fit into 23 1 times, resulting in a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 10 after subtracting 13 from 23.
Include the next digit (9) from the dividend after 10, then repeat: 109 / 13

Moving on to step 3:
109 divided by 13 is 8 with a remainder of 5.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
If we subtract 104 from 109, we get 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 13

Moving on to step 4:
The number 13 fits into 59 4 times, leaving a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 184.0
If we take 52 away from 59, we end up with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 13

Going ahead to step 5:
78 divided by 13 is 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 1846.0
Subtracting 78 from 78 leaves us with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 13

Step 6:
13 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 18460.0
The remainder is 9 after subtracting 0 from 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 7:
When dividing 90 by 13, we get 6 with a remainder of 12.
The next digit of our result is 6. 
Result so far: 18460.6
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.

Going ahead to step 8:
The number 13 fits into 120 9 times, leaving a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 18460.69
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.

Going ahead to step 9:
13 goes into 30 2 times with a remainder of 4.
The next digit of our result is 2. 
Result so far: 18460.692
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.

Let's proceed to step 10:
The number 13 fits into 40 3 times, leaving a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 18460.6923
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.

On to step 11:
The number 13 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 18460.6923
If we take 0 away from 10, 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.

Advancing to step 12:
The number 13 fits into 100 7 times, leaving a remainder of 9.
The next digit of our result is 7. 
Result so far: 18460.692307
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.

Step 13:
13 goes into 90 6 times with a remainder of 12.
The next digit of our result is 6. 
Result so far: 18460.6923076
If we take 78 away from 90, we end up 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.

Moving on to step 14:
13 goes into 120 9 times with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 18460.69230769
If we subtract 117 from 120, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final result is 18460.69230769 with a remainder of 3e-09.
