293988 ÷ 13 
The aim is to understand the frequency of 13 in 293988.

Going ahead to step 1:
2 divided by 13 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 13

Let's proceed to step 2:
29 divided by 13 is 2 with a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 26 from 29 and we're left with 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 13

Moving on to step 3:
If we divide 33 by 13, we get 2 and a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
The remainder is 7 after subtracting 26 from 33.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 13

Advancing to step 4:
The number 13 fits into 79 6 times, leaving a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 226.0
If we take 78 away from 79, we end up with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 13

Moving on to step 5:
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: 2261.0
Subtract 13 from 18 to get 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 13

Moving on to step 6:
If we divide 58 by 13, we get 4 and a remainder of 6.
The next digit of our result is 4. 
Result so far: 22614.0
If we subtract 52 from 58, we 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.

Moving on to step 7:
When dividing 60 by 13, we get 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 22614.4
The remainder is 8 after subtracting 52 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 8:
80 divided by 13 is 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 22614.46
If we subtract 78 from 80, we 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.

Let's proceed to step 9:
13 can be fit into 20 1 times, resulting in a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 22614.461
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.

On to step 10:
70 divided by 13 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 22614.4615
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.

Let's proceed to step 11:
The number 13 fits into 50 3 times, leaving a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 22614.46153
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 12:
The number 13 fits into 110 8 times, leaving a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 22614.461538
If we subtract 104 from 110, we 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 13:
When dividing 60 by 13, we get 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 22614.4615384
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.

Let's proceed to step 14:
80 divided by 13 is 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 22614.46153846
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.

The quotient of the division is 22614.46153846, and the remainder is 2e-09.
