We're dividing 44035700 by 13 
The aim is to understand the frequency of 13 in 44035700.

Going ahead to step 1:
If we divide 4 by 13, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 13

Let's proceed to step 2:
44 divided by 13 is 3 with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 39 from 44 leaves us with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 13

Moving on to step 3:
13 goes into 50 3 times with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 33.0
If we take 39 away from 50, we end up with 11.
Fetch the next digit (3) from the dividend, attach it to 11 and continue: 113 / 13

Step 4:
If we divide 113 by 13, we get 8 and a remainder of 9.
Use 8 as the next digit of our solution. 
Result so far: 338.0
The remainder is 9 after subtracting 104 from 113.
Grab the next digit (5) from the dividend, add it to 9, then carry on: 95 / 13

Step 5:
If we divide 95 by 13, we get 7 and a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 3387.0
If we subtract 91 from 95, we get 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 13

Going ahead to step 6:
47 divided by 13 is 3 with a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 33873.0
The remainder is 8 after subtracting 39 from 47.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 13

Advancing to step 7:
If we divide 80 by 13, we get 6 and a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 338736.0
Subtracting 78 from 80 leaves us with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 13

Let's proceed to step 8:
If we divide 20 by 13, we get 1 and a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 3387361.0
If we take 13 away from 20, we end up 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.

Going ahead to step 9:
13 can be fit into 70 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 3387361.5
The remainder is 5 after subtracting 65 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 10:
50 divided by 13 is 3 with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 3387361.53
If we subtract 39 from 50, we get 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 11:
When dividing 110 by 13, we get 8 with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 3387361.538
Subtract 104 from 110 to 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.

Going ahead to step 12:
If we divide 60 by 13, we get 4 and a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 3387361.5384
Subtracting 52 from 60 leaves us 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.

Moving on to step 13:
13 goes into 80 6 times with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 3387361.53846
The remainder is 2 after subtracting 78 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 14:
13 goes into 20 1 times with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 3387361.538461
Subtract 13 from 20 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 15:
13 goes into 70 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 3387361.5384615
The remainder is 5 after subtracting 65 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 16:
13 goes into 50 3 times with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 3387361.53846153
Subtract 39 from 50 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final result is 3387361.53846153 with a remainder of 1.1e-08.
