We're dividing 12386939 by 235 
The aim is to understand the frequency of 235 in 12386939.

Going ahead to step 1:
When dividing 1 by 235, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 235

Step 2:
When dividing 12 by 235, we get 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Include the next digit (3) from the dividend after 12, then repeat: 123 / 235

Step 3:
The number 235 fits into 123 0 times, leaving a remainder of 123.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 123 and we're left with 123.
Take the next digit (8) from the dividend and append it to 123, then repeat: 1238 / 235

Going ahead to step 4:
The number 235 fits into 1238 5 times, leaving a remainder of 63.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 1175 away from 1238, we end up with 63.
Append the next digit (6) from the dividend to 63 and continue with: 636 / 235

Advancing to step 5:
When dividing 636 by 235, we get 2 with a remainder of 166.
Record the quotient 2 as the next digit in the result. 
Result so far: 52.0
Subtracting 470 from 636 leaves us with 166.
Grab the next digit (9) from the dividend, add it to 166, then carry on: 1669 / 235

Step 6:
235 can be fit into 1669 7 times, resulting in a remainder of 24.
Use 7 as the next digit of our solution. 
Result so far: 527.0
Subtract 1645 from 1669 to get 24.
Include the next digit (3) from the dividend after 24, then repeat: 243 / 235

Let's proceed to step 7:
When dividing 243 by 235, we get 1 with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 5271.0
The remainder is 8 after subtracting 235 from 243.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 235

Going ahead to step 8:
235 goes into 89 0 times with a remainder of 89.
The number 0 becomes the next digit in our result. 
Result so far: 52710.0
The remainder is 89 after subtracting 0 from 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Going ahead to step 9:
890 divided by 235 is 3 with a remainder of 185.
Put 3 as the next digit of the answer. 
Result so far: 52710.3
Subtracting 705 from 890 leaves us with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Moving on to step 10:
235 can be fit into 1850 7 times, resulting in a remainder of 205.
The number 7 becomes the next digit in our result. 
Result so far: 52710.37
Subtract 1645 from 1850 to get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Step 11:
If we divide 2050 by 235, we get 8 and a remainder of 170.
The next digit of our result is 8. 
Result so far: 52710.378
If we take 1880 away from 2050, 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 12:
235 goes into 1700 7 times with a remainder of 55.
The next digit of our result is 7. 
Result so far: 52710.3787
The remainder is 55 after subtracting 1645 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 13:
235 goes into 550 2 times with a remainder of 80.
Use 2 as the next digit of our solution. 
Result so far: 52710.37872
Subtract 470 from 550 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 14:
The number 235 fits into 800 3 times, leaving a remainder of 95.
Put 3 as the next digit of the answer. 
Result so far: 52710.378723
Subtracting 705 from 800 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

On to step 15:
When dividing 950 by 235, we get 4 with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 52710.3787234
If we take 940 away from 950, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 16:
If we divide 100 by 235, we get 0 and a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 52710.3787234
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.

In conclusion, the division gives 52710.3787234 with a balance of 1e-07.
