Let's divide 30912169 by 235
The aim is to understand the frequency of 235 in 30912169.

Advancing to step 1:
When dividing 3 by 235, we get 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.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 235

On to step 2:
235 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Include the next digit (9) from the dividend after 30, then repeat: 309 / 235

Step 3:
The number 235 fits into 309 1 times, leaving a remainder of 74.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 235 from 309 leaves us with 74.
Bring next digit (1) of the dividend behind the 74 and repeat the process: 741 / 235

Step 4:
235 can be fit into 741 3 times, resulting in a remainder of 36.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtract 705 from 741 to get 36.
Include the next digit (2) from the dividend after 36, then repeat: 362 / 235

Let's proceed to step 5:
The number 235 fits into 362 1 times, leaving a remainder of 127.
The number 1 becomes the next digit in our result. 
Result so far: 131.0
Subtract 235 from 362 to get 127.
Append the next digit (1) from the dividend to 127 and continue with: 1271 / 235

Let's proceed to step 6:
235 goes into 1271 5 times with a remainder of 96.
Use 5 as the next digit of our solution. 
Result so far: 1315.0
Deduct 1175 from 1271 and we're left with 96.
Append the next digit (6) from the dividend to 96 and continue with: 966 / 235

Step 7:
235 can be fit into 966 4 times, resulting in a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 13154.0
If we subtract 940 from 966, we get 26.
Take the next digit (9) from the dividend and append it to 26, then repeat: 269 / 235

Let's proceed to step 8:
If we divide 269 by 235, we get 1 and a remainder of 34.
The next digit of our result is 1. 
Result so far: 131541.0
The remainder is 34 after subtracting 235 from 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 9:
When dividing 340 by 235, we get 1 with a remainder of 105.
Write down 1 as next digit of the result. 
Result so far: 131541.1
Subtracting 235 from 340 leaves us with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

On to step 10:
The number 235 fits into 1050 4 times, leaving a remainder of 110.
Write down 4 as next digit of the result. 
Result so far: 131541.14
Subtract 940 from 1050 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 11:
235 can be fit into 1100 4 times, resulting in a remainder of 160.
The next digit of our result is 4. 
Result so far: 131541.144
If we subtract 940 from 1100, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

In conclusion, the division gives 131541.144 with a balance of 0.016.
