744308 divided by 13 
The aim is to understand the frequency of 13 in 744308.

Let's proceed to step 1:
13 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 13

Going ahead to step 2:
The number 13 fits into 74 5 times, leaving a remainder of 9.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 65 away from 74, we end up with 9.
Fetch the next digit (4) from the dividend, attach it to 9 and continue: 94 / 13

Moving on to step 3:
13 can be fit into 94 7 times, resulting in a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 57.0
Deduct 91 from 94 and we're left with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 13

On to step 4:
When dividing 33 by 13, we get 2 with a remainder of 7.
The next digit of our result is 2. 
Result so far: 572.0
Deduct 26 from 33 and we're left with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 13

Moving on to step 5:
70 divided by 13 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 5725.0
If we subtract 65 from 70, we get 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 13

Moving on to step 6:
13 can be fit into 58 4 times, resulting in a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 57254.0
If we take 52 away from 58, 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.

On to step 7:
60 divided by 13 is 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 57254.4
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.

Step 8:
When dividing 80 by 13, we get 6 with a remainder of 2.
The next digit of our result is 6. 
Result so far: 57254.46
Subtract 78 from 80 to 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.

Step 9:
13 can be fit into 20 1 times, resulting in a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 57254.461
Subtracting 13 from 20 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 10:
13 can be fit into 70 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 57254.4615
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.

Step 11:
The number 13 fits into 50 3 times, leaving a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 57254.46153
Subtracting 39 from 50 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 12:
13 can be fit into 110 8 times, resulting in a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 57254.461538
If we subtract 104 from 110, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 13:
13 goes into 60 4 times with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 57254.4615384
If we take 52 away from 60, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 14:
13 can be fit into 80 6 times, resulting in a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 57254.46153846
Subtract 78 from 80 to 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.

In conclusion, the division gives 57254.46153846 with a balance of 2e-09.
