64023046 ÷ 13 
The aim is to understand the frequency of 13 in 64023046.

Let's proceed to step 1:
The number 13 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 13

Going ahead to step 2:
13 goes into 64 4 times with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 52 away from 64, we end up with 12.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 13

Moving on to step 3:
13 goes into 120 9 times with a remainder of 3.
The next digit of our result is 9. 
Result so far: 49.0
If we take 117 away from 120, we end up with 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 13

On to step 4:
When dividing 32 by 13, we get 2 with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 492.0
Deduct 26 from 32 and we're left with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 13

Step 5:
63 divided by 13 is 4 with a remainder of 11.
Put 4 as the next digit of the answer. 
Result so far: 4924.0
Subtract 52 from 63 to get 11.
Take the next digit (0) from the dividend and append it to 11, then repeat: 110 / 13

Moving on to step 6:
13 can be fit into 110 8 times, resulting in a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 49248.0
The remainder is 6 after subtracting 104 from 110.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 13

Moving on to step 7:
64 divided by 13 is 4 with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 492484.0
Subtracting 52 from 64 leaves us with 12.
Grab the next digit (6) from the dividend, add it to 12, then carry on: 126 / 13

On to step 8:
126 divided by 13 is 9 with a remainder of 9.
The next digit of our result is 9. 
Result so far: 4924849.0
Deduct 117 from 126 and we're left 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.

Let's proceed to step 9:
13 can be fit into 90 6 times, resulting in a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 4924849.6
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.

On to step 10:
The number 13 fits into 120 9 times, leaving a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 4924849.69
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.

Moving on to step 11:
13 goes into 30 2 times with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 4924849.692
Subtracting 26 from 30 leaves us 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.

Step 12:
40 divided by 13 is 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 4924849.6923
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.

Let's proceed to step 13:
13 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 4924849.6923
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.

Let's proceed to step 14:
When dividing 100 by 13, we get 7 with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 4924849.692307
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.

Going ahead to step 15:
13 can be fit into 90 6 times, resulting in a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 4924849.6923076
If we subtract 78 from 90, we 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.

On to step 16:
The number 13 fits into 120 9 times, leaving a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 4924849.69230769
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.

The final outcome is 4924849.69230769, with a leftover of 3e-09.
