We look at the division of 52536025 by 239 
The aim is to understand the frequency of 239 in 52536025.

Going ahead to step 1:
239 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 239

Step 2:
If we divide 52 by 239, we get 0 and a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 52 after subtracting 0 from 52.
Bring next digit (5) of the dividend behind the 52 and repeat the process: 525 / 239

Let's proceed to step 3:
525 divided by 239 is 2 with a remainder of 47.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 478 from 525 and we're left with 47.
Grab the next digit (3) from the dividend, add it to 47, then carry on: 473 / 239

Going ahead to step 4:
If we divide 473 by 239, we get 1 and a remainder of 234.
Put 1 as the next digit of the answer. 
Result so far: 21.0
The remainder is 234 after subtracting 239 from 473.
Take the next digit (6) from the dividend and append it to 234, then repeat: 2346 / 239

Advancing to step 5:
If we divide 2346 by 239, we get 9 and a remainder of 195.
Use 9 as the next digit of our solution. 
Result so far: 219.0
Subtracting 2151 from 2346 leaves us with 195.
Bring next digit (0) of the dividend behind the 195 and repeat the process: 1950 / 239

Let's proceed to step 6:
239 goes into 1950 8 times with a remainder of 38.
Use 8 as the next digit of our solution. 
Result so far: 2198.0
Subtract 1912 from 1950 to get 38.
Include the next digit (2) from the dividend after 38, then repeat: 382 / 239

On to step 7:
239 can be fit into 382 1 times, resulting in a remainder of 143.
The next digit of our result is 1. 
Result so far: 21981.0
Subtract 239 from 382 to get 143.
Fetch the next digit (5) from the dividend, attach it to 143 and continue: 1435 / 239

Step 8:
239 goes into 1435 6 times with a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 219816.0
The remainder is 1 after subtracting 1434 from 1435.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 9:
10 divided by 239 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 219816.0
If we subtract 0 from 10, we 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.

Advancing to step 10:
239 can be fit into 100 0 times, resulting in a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 219816.0
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The quotient of the division is 219816.0, and the remainder is 0.1.
