84384596 ÷ 13 
The aim is to understand the frequency of 13 in 84384596.

Let's proceed to step 1:
The number 13 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 13

Moving on to step 2:
13 goes into 84 6 times with a remainder of 6.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 78 from 84 leaves us with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 13

Moving on to step 3:
When dividing 63 by 13, we get 4 with a remainder of 11.
Put 4 as the next digit of the answer. 
Result so far: 64.0
The remainder is 11 after subtracting 52 from 63.
Append the next digit (8) from the dividend to 11 and continue with: 118 / 13

Let's proceed to step 4:
13 can be fit into 118 9 times, resulting in a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 649.0
The remainder is 1 after subtracting 117 from 118.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 13

Advancing to step 5:
The number 13 fits into 14 1 times, leaving a remainder of 1.
The next digit of our result is 1. 
Result so far: 6491.0
If we take 13 away from 14, we end up with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 13

Step 6:
13 goes into 15 1 times with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 64911.0
If we take 13 away from 15, we end up with 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 13

Going ahead to step 7:
If we divide 29 by 13, we get 2 and a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 649112.0
If we subtract 26 from 29, we get 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 13

Step 8:
The number 13 fits into 36 2 times, leaving a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 6491122.0
Subtracting 26 from 36 leaves us 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 9:
13 can be fit into 100 7 times, resulting in a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 6491122.7
The remainder is 9 after subtracting 91 from 100.
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 10:
13 goes into 90 6 times with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 6491122.76
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.

Moving on to step 11:
13 goes into 120 9 times with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 6491122.769
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.

On to step 12:
13 goes into 30 2 times with a remainder of 4.
The next digit of our result is 2. 
Result so far: 6491122.7692
If we take 26 away from 30, we end up with 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 13:
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: 6491122.76923
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.

On to step 14:
If we divide 10 by 13, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 6491122.76923
Subtracting 0 from 10 leaves us 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.

Going ahead to step 15:
When dividing 100 by 13, we get 7 with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 6491122.7692307
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.

Step 16:
13 can be fit into 90 6 times, resulting in a remainder of 12.
The next digit of our result is 6. 
Result so far: 6491122.76923076
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.

The final result is 6491122.76923076 with a remainder of 1.2e-08.
