Let's divide 449037 by 13
The aim is to understand the frequency of 13 in 449037.

Let's proceed to step 1:
When dividing 4 by 13, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 13

Moving on to step 2:
If we divide 44 by 13, we get 3 and a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 39 from 44, we get 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 13

Let's proceed to step 3:
The number 13 fits into 59 4 times, leaving a remainder of 7.
Write down 4 as next digit of the result. 
Result so far: 34.0
If we subtract 52 from 59, we get 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 13

Advancing to step 4:
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: 345.0
Subtract 65 from 70 to get 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 13

Step 5:
When dividing 53 by 13, we get 4 with a remainder of 1.
The next digit of our result is 4. 
Result so far: 3454.0
If we subtract 52 from 53, we get 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 13

Step 6:
If we divide 17 by 13, we get 1 and a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 34541.0
Subtracting 13 from 17 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.

Going ahead to step 7:
The number 13 fits into 40 3 times, leaving a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 34541.3
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.

On to step 8:
10 divided by 13 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 34541.3
Deduct 0 from 10 and we're left 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.

On to step 9:
The number 13 fits into 100 7 times, leaving a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 34541.307
Deduct 91 from 100 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 10:
13 goes into 90 6 times with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 34541.3076
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.

Let's proceed to step 11:
The number 13 fits into 120 9 times, leaving a remainder of 3.
The next digit of our result is 9. 
Result so far: 34541.30769
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 12:
13 goes into 30 2 times with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 34541.307692
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.

Advancing to step 13:
13 goes into 40 3 times with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 34541.3076923
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.

Let's proceed to step 14:
The number 13 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 34541.3076923
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.

The final outcome is 34541.3076923, with a leftover of 1e-08.
