We look at the division of 33239514 by 235 
The aim is to understand the frequency of 235 in 33239514.

Going ahead to step 1:
3 divided by 235 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 235

Let's proceed to step 2:
If we divide 33 by 235, we get 0 and a remainder of 33.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 33 and we're left with 33.
Take the next digit (2) from the dividend and append it to 33, then repeat: 332 / 235

Going ahead to step 3:
332 divided by 235 is 1 with a remainder of 97.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 235 away from 332, we end up with 97.
Include the next digit (3) from the dividend after 97, then repeat: 973 / 235

Moving on to step 4:
If we divide 973 by 235, we get 4 and a remainder of 33.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
The remainder is 33 after subtracting 940 from 973.
Bring next digit (9) of the dividend behind the 33 and repeat the process: 339 / 235

Going ahead to step 5:
When dividing 339 by 235, we get 1 with a remainder of 104.
Record the quotient 1 as the next digit in the result. 
Result so far: 141.0
Subtract 235 from 339 to get 104.
Append the next digit (5) from the dividend to 104 and continue with: 1045 / 235

Advancing to step 6:
If we divide 1045 by 235, we get 4 and a remainder of 105.
The next digit of our result is 4. 
Result so far: 1414.0
If we take 940 away from 1045, we end up with 105.
Include the next digit (1) from the dividend after 105, then repeat: 1051 / 235

Step 7:
1051 divided by 235 is 4 with a remainder of 111.
Put 4 as the next digit of the answer. 
Result so far: 14144.0
If we subtract 940 from 1051, we get 111.
Fetch the next digit (4) from the dividend, attach it to 111 and continue: 1114 / 235

Going ahead to step 8:
1114 divided by 235 is 4 with a remainder of 174.
The number 4 becomes the next digit in our result. 
Result so far: 141444.0
The remainder is 174 after subtracting 940 from 1114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Step 9:
235 can be fit into 1740 7 times, resulting in a remainder of 95.
Put 7 as the next digit of the answer. 
Result so far: 141444.7
Subtracting 1645 from 1740 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.

Let's proceed to step 10:
If we divide 950 by 235, we get 4 and a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 141444.74
Subtracting 940 from 950 leaves us 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.

Advancing to step 11:
The number 235 fits into 100 0 times, leaving a remainder of 100.
The next digit of our result is 0. 
Result so far: 141444.74
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 12:
When dividing 1000 by 235, we get 4 with a remainder of 60.
Put 4 as the next digit of the answer. 
Result so far: 141444.7404
Subtracting 940 from 1000 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 13:
235 goes into 600 2 times with a remainder of 130.
Use 2 as the next digit of our solution. 
Result so far: 141444.74042
Deduct 470 from 600 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 14:
235 goes into 1300 5 times with a remainder of 125.
Use 5 as the next digit of our solution. 
Result so far: 141444.740425
Subtracting 1175 from 1300 leaves us with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Advancing to step 15:
The number 235 fits into 1250 5 times, leaving a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 141444.7404255
The remainder is 75 after subtracting 1175 from 1250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

The final outcome is 141444.7404255, with a leftover of 7.5e-07.
