392328 divided by 13 
The aim is to understand the frequency of 13 in 392328.

Advancing to step 1:
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: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 13

Advancing to step 2:
If we divide 39 by 13, we get 3 and a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 39 from 39, we get 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 13

Moving on to step 3:
If we divide 2 by 13, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 13

Step 4:
If we divide 23 by 13, we get 1 and a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 301.0
Subtracting 13 from 23 leaves us with 10.
Take the next digit (2) from the dividend and append it to 10, then repeat: 102 / 13

Advancing to step 5:
13 can be fit into 102 7 times, resulting in a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 3017.0
Subtracting 91 from 102 leaves us with 11.
Bring next digit (8) of the dividend behind the 11 and repeat the process: 118 / 13

Moving on to step 6:
13 goes into 118 9 times with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 30179.0
Subtract 117 from 118 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.

Advancing to step 7:
The number 13 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 30179.0
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.

Advancing to step 8:
13 can be fit into 100 7 times, resulting in a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 30179.07
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.

On to step 9:
13 goes into 90 6 times with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 30179.076
Subtract 78 from 90 to 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.

Moving on to step 10:
13 goes into 120 9 times with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 30179.0769
Subtract 117 from 120 to 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.

Let's proceed to step 11:
When dividing 30 by 13, we get 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 30179.07692
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.

Step 12:
40 divided by 13 is 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 30179.076923
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.

Advancing to step 13:
13 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 30179.076923
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.

Let's proceed to step 14:
13 goes into 100 7 times with a remainder of 9.
The next digit of our result is 7. 
Result so far: 30179.07692307
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.

The final outcome is 30179.07692307, with a leftover of 9e-09.
