Let's divide 15955955 by 239
The aim is to understand the frequency of 239 in 15955955.

On to step 1:
239 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 239

Going ahead to step 2:
239 can be fit into 15 0 times, resulting in a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Append the next digit (9) from the dividend to 15 and continue with: 159 / 239

Moving on to step 3:
If we divide 159 by 239, we get 0 and a remainder of 159.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 159, we get 159.
Take the next digit (5) from the dividend and append it to 159, then repeat: 1595 / 239

Moving on to step 4:
239 goes into 1595 6 times with a remainder of 161.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtracting 1434 from 1595 leaves us with 161.
Grab the next digit (5) from the dividend, add it to 161, then carry on: 1615 / 239

Step 5:
239 can be fit into 1615 6 times, resulting in a remainder of 181.
The number 6 becomes the next digit in our result. 
Result so far: 66.0
The remainder is 181 after subtracting 1434 from 1615.
Grab the next digit (9) from the dividend, add it to 181, then carry on: 1819 / 239

Advancing to step 6:
1819 divided by 239 is 7 with a remainder of 146.
The number 7 becomes the next digit in our result. 
Result so far: 667.0
The remainder is 146 after subtracting 1673 from 1819.
Append the next digit (5) from the dividend to 146 and continue with: 1465 / 239

Let's proceed to step 7:
When dividing 1465 by 239, we get 6 with a remainder of 31.
The number 6 becomes the next digit in our result. 
Result so far: 6676.0
If we take 1434 away from 1465, we end up with 31.
Include the next digit (5) from the dividend after 31, then repeat: 315 / 239

Step 8:
239 can be fit into 315 1 times, resulting in a remainder of 76.
Record the quotient 1 as the next digit in the result. 
Result so far: 66761.0
Deduct 239 from 315 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 9:
If we divide 760 by 239, we get 3 and a remainder of 43.
Record the quotient 3 as the next digit in the result. 
Result so far: 66761.3
Subtracting 717 from 760 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 10:
430 divided by 239 is 1 with a remainder of 191.
Use 1 as the next digit of our solution. 
Result so far: 66761.31
Subtracting 239 from 430 leaves us with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Advancing to step 11:
1910 divided by 239 is 7 with a remainder of 237.
Use 7 as the next digit of our solution. 
Result so far: 66761.317
Subtract 1673 from 1910 to get 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

On to step 12:
If we divide 2370 by 239, we get 9 and a remainder of 219.
Write down 9 as next digit of the result. 
Result so far: 66761.3179
If we take 2151 away from 2370, we end up with 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Step 13:
239 goes into 2190 9 times with a remainder of 39.
Record the quotient 9 as the next digit in the result. 
Result so far: 66761.31799
Subtracting 2151 from 2190 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The final outcome is 66761.31799, with a leftover of 3.9e-05.
