We're dividing 2497 by 13 
The aim is to understand the frequency of 13 in 2497.

Advancing to step 1:
If we divide 2 by 13, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 13

Step 2:
The number 13 fits into 24 1 times, leaving a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 13 from 24, we get 11.
Bring next digit (9) of the dividend behind the 11 and repeat the process: 119 / 13

Let's proceed to step 3:
119 divided by 13 is 9 with a remainder of 2.
The next digit of our result is 9. 
Result so far: 19.0
Deduct 117 from 119 and we're left with 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 13

Let's proceed to step 4:
27 divided by 13 is 2 with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 192.0
The remainder is 1 after subtracting 26 from 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 5:
13 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 192.0
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 6:
13 goes into 100 7 times with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 192.07
If we take 91 away from 100, we end up 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.

On to step 7:
13 can be fit into 90 6 times, resulting in a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 192.076
Subtract 78 from 90 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 8:
If we divide 120 by 13, we get 9 and a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 192.0769
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.

Advancing to step 9:
30 divided by 13 is 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 192.07692
The remainder is 4 after subtracting 26 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
13 goes into 40 3 times with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 192.076923
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.

Advancing to step 11:
When dividing 10 by 13, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 192.076923
Subtracting 0 from 10 leaves us 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.

Moving on to step 12:
13 goes into 100 7 times with a remainder of 9.
The next digit of our result is 7. 
Result so far: 192.07692307
Subtracting 91 from 100 leaves us 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.

The final result is 192.07692307 with a remainder of 9e-09.
