234450 divided by 13 
The aim is to understand the frequency of 13 in 234450.

Step 1:
When dividing 2 by 13, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 13

Let's proceed to step 2:
When dividing 23 by 13, we get 1 with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 13 from 23, we get 10.
Grab the next digit (4) from the dividend, add it to 10, then carry on: 104 / 13

Step 3:
The number 13 fits into 104 8 times, leaving a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
If we take 104 away from 104, we end up with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 13

Going ahead to step 4:
13 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 180.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 13

Moving on to step 5:
When dividing 45 by 13, we get 3 with a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 1803.0
The remainder is 6 after subtracting 39 from 45.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 13

Moving on to step 6:
60 divided by 13 is 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 18034.0
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.

On to step 7:
13 can be fit into 80 6 times, resulting in a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 18034.6
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.

On to step 8:
If we divide 20 by 13, we get 1 and a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 18034.61
Deduct 13 from 20 and we're left 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 9:
If we divide 70 by 13, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 18034.615
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.

Moving on to step 10:
13 goes into 50 3 times with a remainder of 11.
The next digit of our result is 3. 
Result so far: 18034.6153
If we subtract 39 from 50, we 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.

Let's proceed to step 11:
When dividing 110 by 13, we get 8 with a remainder of 6.
The next digit of our result is 8. 
Result so far: 18034.61538
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.

On to step 12:
13 goes into 60 4 times with a remainder of 8.
The next digit of our result is 4. 
Result so far: 18034.615384
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.

Moving on to step 13:
13 can be fit into 80 6 times, resulting in a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 18034.6153846
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.

Advancing to step 14:
When dividing 20 by 13, we get 1 with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 18034.61538461
Subtract 13 from 20 to 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.

In conclusion, the division gives 18034.61538461 with a balance of 7e-09.
