14843221 ÷ 13 
The aim is to understand the frequency of 13 in 14843221.

Step 1:
13 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 13

Moving on to step 2:
14 divided by 13 is 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 13 from 14, we get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 13

Moving on to step 3:
13 can be fit into 18 1 times, resulting in a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 11.0
The remainder is 5 after subtracting 13 from 18.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 13

Let's proceed to step 4:
When dividing 54 by 13, we get 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 114.0
Subtract 52 from 54 to get 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 13

Moving on to step 5:
When dividing 23 by 13, we get 1 with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 1141.0
If we subtract 13 from 23, we get 10.
Grab the next digit (2) from the dividend, add it to 10, then carry on: 102 / 13

On to step 6:
When dividing 102 by 13, we get 7 with a remainder of 11.
The next digit of our result is 7. 
Result so far: 11417.0
If we take 91 away from 102, we end up with 11.
Include the next digit (2) from the dividend after 11, then repeat: 112 / 13

Going ahead to step 7:
112 divided by 13 is 8 with a remainder of 8.
The next digit of our result is 8. 
Result so far: 114178.0
If we subtract 104 from 112, we get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 13

Step 8:
The number 13 fits into 81 6 times, leaving a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 1141786.0
If we subtract 78 from 81, we 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.

On to step 9:
13 can be fit into 30 2 times, resulting in a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 1141786.2
If we take 26 away from 30, we end up 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 10:
40 divided by 13 is 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 1141786.23
Subtracting 39 from 40 leaves us 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 11:
If we divide 10 by 13, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 1141786.23
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.

Step 12:
If we divide 100 by 13, we get 7 and a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 1141786.2307
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 13:
When dividing 90 by 13, we get 6 with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 1141786.23076
The remainder is 12 after subtracting 78 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 14:
120 divided by 13 is 9 with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 1141786.230769
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.

On to step 15:
If we divide 30 by 13, we get 2 and a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 1141786.2307692
Subtract 26 from 30 to 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.

Let's proceed to step 16:
13 can be fit into 40 3 times, resulting in a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 1141786.23076923
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.

The quotient of the division is 1141786.23076923, and the remainder is 1e-09.
