We're dividing 179964 by 13 
The aim is to understand the frequency of 13 in 179964.

Let's proceed to step 1:
13 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 13

Step 2:
17 divided by 13 is 1 with a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 13 from 17 to get 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 13

Let's proceed to step 3:
If we divide 49 by 13, we get 3 and a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtracting 39 from 49 leaves us with 10.
Append the next digit (9) from the dividend to 10 and continue with: 109 / 13

Moving on to step 4:
If we divide 109 by 13, we get 8 and a remainder of 5.
Put 8 as the next digit of the answer. 
Result so far: 138.0
Subtract 104 from 109 to get 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 13

Going ahead to step 5:
The number 13 fits into 56 4 times, leaving a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 1384.0
Subtract 52 from 56 to get 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 13

Moving on to step 6:
13 can be fit into 44 3 times, resulting in a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 13843.0
Subtracting 39 from 44 leaves us 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.

Moving on to step 7:
The number 13 fits into 50 3 times, leaving a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 13843.3
The remainder is 11 after subtracting 39 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 8:
13 can be fit into 110 8 times, resulting in a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 13843.38
If we take 104 away from 110, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
The number 13 fits into 60 4 times, leaving a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 13843.384
The remainder is 8 after subtracting 52 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
The number 13 fits into 80 6 times, leaving a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 13843.3846
If we subtract 78 from 80, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 11:
13 goes into 20 1 times with a remainder of 7.
The next digit of our result is 1. 
Result so far: 13843.38461
If we subtract 13 from 20, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 12:
13 goes into 70 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 13843.384615
If we take 65 away from 70, 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.

On to step 13:
When dividing 50 by 13, we get 3 with a remainder of 11.
The next digit of our result is 3. 
Result so far: 13843.3846153
Subtract 39 from 50 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 14:
If we divide 110 by 13, we get 8 and a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 13843.38461538
If we take 104 away from 110, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final result is 13843.38461538 with a remainder of 6e-09.
