We divide 248173 by 13
The aim is to understand the frequency of 13 in 248173.

Moving on to step 1:
The number 13 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 13

On to step 2:
If we divide 24 by 13, we get 1 and a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 13 away from 24, we end up with 11.
Take the next digit (8) from the dividend and append it to 11, then repeat: 118 / 13

Advancing to step 3:
If we divide 118 by 13, we get 9 and a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Subtract 117 from 118 to get 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 13

Step 4:
13 goes into 11 0 times with a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 190.0
If we subtract 0 from 11, we get 11.
Fetch the next digit (7) from the dividend, attach it to 11 and continue: 117 / 13

Step 5:
117 divided by 13 is 9 with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 1909.0
Subtracting 117 from 117 leaves us with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 13

Moving on to step 6:
13 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 19090.0
The remainder is 3 after subtracting 0 from 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
13 goes into 30 2 times with a remainder of 4.
The next digit of our result is 2. 
Result so far: 19090.2
Subtracting 26 from 30 leaves us 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.

Advancing to step 8:
40 divided by 13 is 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 19090.23
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.

Moving on to step 9:
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: 19090.23
Subtract 0 from 10 to 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.

On to step 10:
13 can be fit into 100 7 times, resulting in a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 19090.2307
The remainder is 9 after subtracting 91 from 100.
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 11:
90 divided by 13 is 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 19090.23076
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.

Let's proceed to step 12:
13 can be fit into 120 9 times, resulting in a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 19090.230769
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.

Advancing to step 13:
13 goes into 30 2 times with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 19090.2307692
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 14:
The number 13 fits into 40 3 times, leaving a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 19090.23076923
Subtract 39 from 40 to 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.

The final outcome is 19090.23076923, with a leftover of 1e-09.
