43925490 ÷ 239 
The aim is to understand the frequency of 239 in 43925490.

Moving on to step 1:
4 divided by 239 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 239

On to step 2:
43 divided by 239 is 0 with a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Bring next digit (9) of the dividend behind the 43 and repeat the process: 439 / 239

Going ahead to step 3:
439 divided by 239 is 1 with a remainder of 200.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 239 from 439 leaves us with 200.
Fetch the next digit (2) from the dividend, attach it to 200 and continue: 2002 / 239

Going ahead to step 4:
The number 239 fits into 2002 8 times, leaving a remainder of 90.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Deduct 1912 from 2002 and we're left with 90.
Bring next digit (5) of the dividend behind the 90 and repeat the process: 905 / 239

Step 5:
905 divided by 239 is 3 with a remainder of 188.
The next digit of our result is 3. 
Result so far: 183.0
Deduct 717 from 905 and we're left with 188.
Bring next digit (4) of the dividend behind the 188 and repeat the process: 1884 / 239

Let's proceed to step 6:
The number 239 fits into 1884 7 times, leaving a remainder of 211.
Put 7 as the next digit of the answer. 
Result so far: 1837.0
Deduct 1673 from 1884 and we're left with 211.
Append the next digit (9) from the dividend to 211 and continue with: 2119 / 239

Let's proceed to step 7:
239 goes into 2119 8 times with a remainder of 207.
Write down 8 as next digit of the result. 
Result so far: 18378.0
Subtracting 1912 from 2119 leaves us with 207.
Take the next digit (0) from the dividend and append it to 207, then repeat: 2070 / 239

Going ahead to step 8:
239 goes into 2070 8 times with a remainder of 158.
Record the quotient 8 as the next digit in the result. 
Result so far: 183788.0
Deduct 1912 from 2070 and we're left with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Advancing to step 9:
1580 divided by 239 is 6 with a remainder of 146.
Use 6 as the next digit of our solution. 
Result so far: 183788.6
Subtract 1434 from 1580 to get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Moving on to step 10:
239 can be fit into 1460 6 times, resulting in a remainder of 26.
Record the quotient 6 as the next digit in the result. 
Result so far: 183788.66
Subtracting 1434 from 1460 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final result is 183788.66 with a remainder of 0.026.
