We're dividing 19641603 by 239 
The aim is to understand the frequency of 239 in 19641603.

Moving on to step 1:
If we divide 1 by 239, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 239

Going ahead to step 2:
When dividing 19 by 239, we get 0 with a remainder of 19.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 19, we get 19.
Include the next digit (6) from the dividend after 19, then repeat: 196 / 239

Let's proceed to step 3:
If we divide 196 by 239, we get 0 and a remainder of 196.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 196, we get 196.
Take the next digit (4) from the dividend and append it to 196, then repeat: 1964 / 239

On to step 4:
239 can be fit into 1964 8 times, resulting in a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 1912 away from 1964, we end up with 52.
Take the next digit (1) from the dividend and append it to 52, then repeat: 521 / 239

Advancing to step 5:
521 divided by 239 is 2 with a remainder of 43.
Write down 2 as next digit of the result. 
Result so far: 82.0
Subtract 478 from 521 to get 43.
Bring next digit (6) of the dividend behind the 43 and repeat the process: 436 / 239

Moving on to step 6:
436 divided by 239 is 1 with a remainder of 197.
The number 1 becomes the next digit in our result. 
Result so far: 821.0
Subtract 239 from 436 to get 197.
Fetch the next digit (0) from the dividend, attach it to 197 and continue: 1970 / 239

Let's proceed to step 7:
If we divide 1970 by 239, we get 8 and a remainder of 58.
Put 8 as the next digit of the answer. 
Result so far: 8218.0
If we take 1912 away from 1970, we end up with 58.
Fetch the next digit (3) from the dividend, attach it to 58 and continue: 583 / 239

Step 8:
239 can be fit into 583 2 times, resulting in a remainder of 105.
The number 2 becomes the next digit in our result. 
Result so far: 82182.0
Subtract 478 from 583 to get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Let's proceed to step 9:
If we divide 1050 by 239, we get 4 and a remainder of 94.
Use 4 as the next digit of our solution. 
Result so far: 82182.4
If we take 956 away from 1050, we end up with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Let's proceed to step 10:
If we divide 940 by 239, we get 3 and a remainder of 223.
Put 3 as the next digit of the answer. 
Result so far: 82182.43
If we subtract 717 from 940, we get 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Advancing to step 11:
The number 239 fits into 2230 9 times, leaving a remainder of 79.
Write down 9 as next digit of the result. 
Result so far: 82182.439
Subtracting 2151 from 2230 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Advancing to step 12:
239 can be fit into 790 3 times, resulting in a remainder of 73.
Write down 3 as next digit of the result. 
Result so far: 82182.4393
Subtract 717 from 790 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 13:
The number 239 fits into 730 3 times, leaving a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 82182.43933
Subtracting 717 from 730 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

After the division, we end up with 82182.43933 and a remainder of 1.3e-05.
