We look at the division of 3043829 by 243 
The aim is to understand the frequency of 243 in 3043829.

Step 1:
When dividing 3 by 243, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 243

On to step 2:
The number 243 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Fetch the next digit (4) from the dividend, attach it to 30 and continue: 304 / 243

Let's proceed to step 3:
243 goes into 304 1 times with a remainder of 61.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 243 from 304, we get 61.
Include the next digit (3) from the dividend after 61, then repeat: 613 / 243

Going ahead to step 4:
243 can be fit into 613 2 times, resulting in a remainder of 127.
The next digit of our result is 2. 
Result so far: 12.0
Subtracting 486 from 613 leaves us with 127.
Bring next digit (8) of the dividend behind the 127 and repeat the process: 1278 / 243

Step 5:
243 goes into 1278 5 times with a remainder of 63.
The next digit of our result is 5. 
Result so far: 125.0
The remainder is 63 after subtracting 1215 from 1278.
Take the next digit (2) from the dividend and append it to 63, then repeat: 632 / 243

On to step 6:
243 can be fit into 632 2 times, resulting in a remainder of 146.
The number 2 becomes the next digit in our result. 
Result so far: 1252.0
Subtract 486 from 632 to get 146.
Take the next digit (9) from the dividend and append it to 146, then repeat: 1469 / 243

Going ahead to step 7:
If we divide 1469 by 243, we get 6 and a remainder of 11.
Record the quotient 6 as the next digit in the result. 
Result so far: 12526.0
If we subtract 1458 from 1469, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 8:
243 goes into 110 0 times with a remainder of 110.
Record the quotient 0 as the next digit in the result. 
Result so far: 12526.0
If we subtract 0 from 110, we 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.

Step 9:
1100 divided by 243 is 4 with a remainder of 128.
The number 4 becomes the next digit in our result. 
Result so far: 12526.04
Deduct 972 from 1100 and we're left with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 10:
243 goes into 1280 5 times with a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 12526.045
If we take 1215 away from 1280, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 11:
When dividing 650 by 243, we get 2 with a remainder of 164.
Record the quotient 2 as the next digit in the result. 
Result so far: 12526.0452
The remainder is 164 after subtracting 486 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Step 12:
If we divide 1640 by 243, we get 6 and a remainder of 182.
Record the quotient 6 as the next digit in the result. 
Result so far: 12526.04526
Deduct 1458 from 1640 and we're left with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Let's proceed to step 13:
When dividing 1820 by 243, we get 7 with a remainder of 119.
The next digit of our result is 7. 
Result so far: 12526.045267
Subtracting 1701 from 1820 leaves us with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Moving on to step 14:
The number 243 fits into 1190 4 times, leaving a remainder of 218.
The next digit of our result is 4. 
Result so far: 12526.0452674
Subtract 972 from 1190 to get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Let's proceed to step 15:
If we divide 2180 by 243, we get 8 and a remainder of 236.
Use 8 as the next digit of our solution. 
Result so far: 12526.04526748
If we subtract 1944 from 2180, we get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

After the division, we end up with 12526.04526748 and a remainder of 2.36e-07.
