302707 ÷ 13 
The aim is to understand the frequency of 13 in 302707.

Moving on to step 1:
If we divide 3 by 13, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 13

Going ahead to step 2:
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: 2.0
Deduct 26 from 30 and we're left with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 13

Advancing to step 3:
42 divided by 13 is 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 23.0
If we take 39 away from 42, we end up with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 13

Let's proceed to step 4:
When dividing 37 by 13, we get 2 with a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 232.0
Subtracting 26 from 37 leaves us with 11.
Grab the next digit (0) from the dividend, add it to 11, then carry on: 110 / 13

Let's proceed to step 5:
When dividing 110 by 13, we get 8 with a remainder of 6.
The next digit of our result is 8. 
Result so far: 2328.0
Subtract 104 from 110 to get 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 13

On to step 6:
When dividing 67 by 13, we get 5 with a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 23285.0
Subtract 65 from 67 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.

Advancing to step 7:
The number 13 fits into 20 1 times, leaving a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 23285.1
If we subtract 13 from 20, we 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.

Moving on to step 8:
If we divide 70 by 13, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 23285.15
If we subtract 65 from 70, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
50 divided by 13 is 3 with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 23285.153
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.

Step 10:
If we divide 110 by 13, we get 8 and a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 23285.1538
The remainder is 6 after subtracting 104 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 11:
If we divide 60 by 13, we get 4 and a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 23285.15384
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 12:
13 can be fit into 80 6 times, resulting in a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 23285.153846
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.

Step 13:
When dividing 20 by 13, we get 1 with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 23285.1538461
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.

Going ahead to step 14:
13 goes into 70 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 23285.15384615
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.

The quotient of the division is 23285.15384615, and the remainder is 5e-09.
