We look at the division of 27713315 by 13 
The aim is to understand the frequency of 13 in 27713315.

Let's proceed to step 1:
When dividing 2 by 13, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 13

Let's proceed to step 2:
13 goes into 27 2 times with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 1 after subtracting 26 from 27.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 13

Going ahead to step 3:
The number 13 fits into 17 1 times, leaving a remainder of 4.
The next digit of our result is 1. 
Result so far: 21.0
If we subtract 13 from 17, we get 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 13

Step 4:
If we divide 41 by 13, we get 3 and a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 213.0
If we take 39 away from 41, we end up with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 13

On to step 5:
If we divide 23 by 13, we get 1 and a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 2131.0
Subtracting 13 from 23 leaves us with 10.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 13

Step 6:
If we divide 103 by 13, we get 7 and a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 21317.0
Deduct 91 from 103 and we're left with 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 13

Going ahead to step 7:
If we divide 121 by 13, we get 9 and a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 213179.0
The remainder is 4 after subtracting 117 from 121.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 13

On to step 8:
When dividing 45 by 13, we get 3 with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 2131793.0
If we subtract 39 from 45, 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 9:
The number 13 fits into 60 4 times, leaving a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 2131793.4
Deduct 52 from 60 and we're left 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 10:
80 divided by 13 is 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 2131793.46
If we take 78 away from 80, we end up 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.

Moving on to step 11:
13 goes into 20 1 times with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 2131793.461
If we take 13 away from 20, we end up 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 12:
When dividing 70 by 13, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 2131793.4615
Subtracting 65 from 70 leaves us 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.

Advancing to step 13:
When dividing 50 by 13, we get 3 with a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 2131793.46153
Subtracting 39 from 50 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 14:
110 divided by 13 is 8 with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 2131793.461538
Deduct 104 from 110 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 15:
13 can be fit into 60 4 times, resulting in a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 2131793.4615384
If we subtract 52 from 60, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 16:
80 divided by 13 is 6 with a remainder of 2.
The next digit of our result is 6. 
Result so far: 2131793.46153846
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.

The quotient of the division is 2131793.46153846, and the remainder is 2e-09.
