We look at the division of 304670 by 13 
The aim is to understand the frequency of 13 in 304670.

Going ahead to step 1:
13 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 13

Let's proceed to step 2:
If we divide 30 by 13, we get 2 and a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 26 from 30 and we're left with 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 13

Step 3:
13 goes into 44 3 times with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 23.0
The remainder is 5 after subtracting 39 from 44.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 13

Moving on to step 4:
When dividing 56 by 13, we get 4 with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 234.0
Deduct 52 from 56 and we're left with 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 13

Step 5:
The number 13 fits into 47 3 times, leaving a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 2343.0
Subtracting 39 from 47 leaves us with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 13

Let's proceed to step 6:
13 goes into 80 6 times with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 23436.0
Deduct 78 from 80 and we're left 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.

Advancing to step 7:
When dividing 20 by 13, we get 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 23436.1
If we subtract 13 from 20, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 8:
70 divided by 13 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 23436.15
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.

Going ahead to step 9:
50 divided by 13 is 3 with a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 23436.153
Subtract 39 from 50 to get 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 10:
13 can be fit into 110 8 times, resulting in a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 23436.1538
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.

Let's proceed to step 11:
13 goes into 60 4 times with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 23436.15384
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.

Going ahead to step 12:
13 can be fit into 80 6 times, resulting in a remainder of 2.
The next digit of our result is 6. 
Result so far: 23436.153846
Subtracting 78 from 80 leaves us 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.

Going ahead to step 13:
If we divide 20 by 13, we get 1 and a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 23436.1538461
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.

Moving on to step 14:
If we divide 70 by 13, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 23436.15384615
Subtract 65 from 70 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

In conclusion, the division gives 23436.15384615 with a balance of 5e-09.
