We divide 178350 by 13
The aim is to understand the frequency of 13 in 178350.

Moving on to step 1:
The number 13 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 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.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 13 away from 17, we end up with 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 13

On to step 3:
The number 13 fits into 48 3 times, leaving a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtract 39 from 48 to get 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 13

Let's proceed to step 4:
13 can be fit into 93 7 times, resulting in a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 137.0
Subtracting 91 from 93 leaves us with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 13

Going ahead to step 5:
If we divide 25 by 13, we get 1 and a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 1371.0
The remainder is 12 after subtracting 13 from 25.
Take the next digit (0) from the dividend and append it to 12, then repeat: 120 / 13

Advancing to step 6:
When dividing 120 by 13, we get 9 with a remainder of 3.
The next digit of our result is 9. 
Result so far: 13719.0
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.

On to step 7:
When dividing 30 by 13, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 13719.2
Subtract 26 from 30 to 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.

Moving on to step 8:
If we divide 40 by 13, we get 3 and a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 13719.23
Subtract 39 from 40 to 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.

Moving on to step 9:
10 divided by 13 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 13719.23
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.

Moving on to step 10:
100 divided by 13 is 7 with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 13719.2307
If we subtract 91 from 100, we 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.

Moving on to step 11:
When dividing 90 by 13, we get 6 with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 13719.23076
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.

Going ahead to step 12:
13 can be fit into 120 9 times, resulting in a remainder of 3.
The next digit of our result is 9. 
Result so far: 13719.230769
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.

Step 13:
When dividing 30 by 13, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 13719.2307692
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 14:
When dividing 40 by 13, we get 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 13719.23076923
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.

The final outcome is 13719.23076923, with a leftover of 1e-09.
