13258064 ÷ 239 
The aim is to understand the frequency of 239 in 13258064.

Going ahead to step 1:
The number 239 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 239

On to step 2:
239 can be fit into 13 0 times, resulting in a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Take the next digit (2) from the dividend and append it to 13, then repeat: 132 / 239

Advancing to step 3:
When dividing 132 by 239, we get 0 with a remainder of 132.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 132 to get 132.
Append the next digit (5) from the dividend to 132 and continue with: 1325 / 239

Let's proceed to step 4:
239 can be fit into 1325 5 times, resulting in a remainder of 130.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 130 after subtracting 1195 from 1325.
Include the next digit (8) from the dividend after 130, then repeat: 1308 / 239

Going ahead to step 5:
The number 239 fits into 1308 5 times, leaving a remainder of 113.
Write down 5 as next digit of the result. 
Result so far: 55.0
Subtract 1195 from 1308 to get 113.
Append the next digit (0) from the dividend to 113 and continue with: 1130 / 239

Let's proceed to step 6:
1130 divided by 239 is 4 with a remainder of 174.
The number 4 becomes the next digit in our result. 
Result so far: 554.0
Deduct 956 from 1130 and we're left with 174.
Take the next digit (6) from the dividend and append it to 174, then repeat: 1746 / 239

On to step 7:
239 can be fit into 1746 7 times, resulting in a remainder of 73.
Write down 7 as next digit of the result. 
Result so far: 5547.0
Deduct 1673 from 1746 and we're left with 73.
Take the next digit (4) from the dividend and append it to 73, then repeat: 734 / 239

Moving on to step 8:
239 can be fit into 734 3 times, resulting in a remainder of 17.
The next digit of our result is 3. 
Result so far: 55473.0
Subtract 717 from 734 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 9:
239 goes into 170 0 times with a remainder of 170.
The next digit of our result is 0. 
Result so far: 55473.0
If we take 0 away from 170, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 10:
239 goes into 1700 7 times with a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 55473.07
Deduct 1673 from 1700 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 11:
The number 239 fits into 270 1 times, leaving a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 55473.071
If we subtract 239 from 270, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 12:
When dividing 310 by 239, we get 1 with a remainder of 71.
Record the quotient 1 as the next digit in the result. 
Result so far: 55473.0711
The remainder is 71 after subtracting 239 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

The final outcome is 55473.0711, with a leftover of 0.00071.
