Let's divide 49924 by 13
The aim is to understand the frequency of 13 in 49924.

Step 1:
4 divided by 13 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 13

Step 2:
When dividing 49 by 13, we get 3 with a remainder of 10.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 39 from 49 to get 10.
Grab the next digit (9) from the dividend, add it to 10, then carry on: 109 / 13

Moving on to step 3:
109 divided by 13 is 8 with a remainder of 5.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
Subtract 104 from 109 to get 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 13

Moving on to step 4:
If we divide 52 by 13, we get 4 and a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 384.0
The remainder is 0 after subtracting 52 from 52.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 13

Step 5:
13 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 3840.0
If we take 0 away from 4, 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 6:
When dividing 40 by 13, we get 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 3840.3
If we take 39 away from 40, we end up 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.

Moving on to step 7:
10 divided by 13 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 3840.3
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.

Step 8:
100 divided by 13 is 7 with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 3840.307
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 9:
If we divide 90 by 13, we get 6 and a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 3840.3076
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.

On to step 10:
If we divide 120 by 13, we get 9 and a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 3840.30769
If we take 117 away from 120, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 11:
13 goes into 30 2 times with a remainder of 4.
The next digit of our result is 2. 
Result so far: 3840.307692
If we subtract 26 from 30, we 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.

On to step 12:
13 can be fit into 40 3 times, resulting in a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 3840.3076923
If we subtract 39 from 40, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 13:
When dividing 10 by 13, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 3840.3076923
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 3840.3076923 and a remainder of 1e-08.
