441387 divided by 13 
The aim is to understand the frequency of 13 in 441387.

Going ahead to step 1:
13 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 13

Moving on to step 2:
13 goes into 44 3 times with a remainder of 5.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 5 after subtracting 39 from 44.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 13

Step 3:
The number 13 fits into 51 3 times, leaving a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
Deduct 39 from 51 and we're left with 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 13

Step 4:
The number 13 fits into 123 9 times, leaving a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 339.0
If we take 117 away from 123, we end up with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 13

Step 5:
The number 13 fits into 68 5 times, leaving a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 3395.0
Subtract 65 from 68 to get 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 13

On to step 6:
When dividing 37 by 13, we get 2 with a remainder of 11.
Write down 2 as next digit of the result. 
Result so far: 33952.0
If we subtract 26 from 37, 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.

Moving on to step 7:
13 can be fit into 110 8 times, resulting in a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 33952.8
If we take 104 away from 110, 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.

Moving on to step 8:
The number 13 fits into 60 4 times, leaving a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 33952.84
If we subtract 52 from 60, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
When dividing 80 by 13, we get 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 33952.846
Subtracting 78 from 80 leaves us with 2.
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 10:
13 goes into 20 1 times with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 33952.8461
Deduct 13 from 20 and we're left 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.

Moving on to step 11:
The number 13 fits into 70 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 33952.84615
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.

Going ahead to step 12:
13 goes into 50 3 times with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 33952.846153
The remainder is 11 after subtracting 39 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 13:
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: 33952.8461538
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.

On to step 14:
If we divide 60 by 13, we get 4 and a remainder of 8.
The next digit of our result is 4. 
Result so far: 33952.84615384
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.

After the division, we end up with 33952.84615384 and a remainder of 8e-09.
