We divide 75229253 by 243
The aim is to understand the frequency of 243 in 75229253.

Let's proceed to step 1:
The number 243 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 243

Moving on to step 2:
The number 243 fits into 75 0 times, leaving a remainder of 75.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 75 to get 75.
Bring next digit (2) of the dividend behind the 75 and repeat the process: 752 / 243

Advancing to step 3:
752 divided by 243 is 3 with a remainder of 23.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 729 away from 752, we end up with 23.
Bring next digit (2) of the dividend behind the 23 and repeat the process: 232 / 243

Moving on to step 4:
243 can be fit into 232 0 times, resulting in a remainder of 232.
Write down 0 as next digit of the result. 
Result so far: 30.0
The remainder is 232 after subtracting 0 from 232.
Include the next digit (9) from the dividend after 232, then repeat: 2329 / 243

Step 5:
243 goes into 2329 9 times with a remainder of 142.
Use 9 as the next digit of our solution. 
Result so far: 309.0
If we take 2187 away from 2329, we end up with 142.
Take the next digit (2) from the dividend and append it to 142, then repeat: 1422 / 243

Moving on to step 6:
When dividing 1422 by 243, we get 5 with a remainder of 207.
Put 5 as the next digit of the answer. 
Result so far: 3095.0
Subtracting 1215 from 1422 leaves us with 207.
Bring next digit (5) of the dividend behind the 207 and repeat the process: 2075 / 243

Let's proceed to step 7:
243 can be fit into 2075 8 times, resulting in a remainder of 131.
The number 8 becomes the next digit in our result. 
Result so far: 30958.0
The remainder is 131 after subtracting 1944 from 2075.
Fetch the next digit (3) from the dividend, attach it to 131 and continue: 1313 / 243

Advancing to step 8:
When dividing 1313 by 243, we get 5 with a remainder of 98.
Write down 5 as next digit of the result. 
Result so far: 309585.0
If we subtract 1215 from 1313, we get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Step 9:
If we divide 980 by 243, we get 4 and a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 309585.4
Subtract 972 from 980 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
If we divide 80 by 243, we get 0 and a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 309585.4
The remainder is 80 after subtracting 0 from 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 11:
When dividing 800 by 243, we get 3 with a remainder of 71.
Use 3 as the next digit of our solution. 
Result so far: 309585.403
Deduct 729 from 800 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 12:
When dividing 710 by 243, we get 2 with a remainder of 224.
The next digit of our result is 2. 
Result so far: 309585.4032
Subtracting 486 from 710 leaves us with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

On to step 13:
The number 243 fits into 2240 9 times, leaving a remainder of 53.
Record the quotient 9 as the next digit in the result. 
Result so far: 309585.40329
Deduct 2187 from 2240 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 14:
If we divide 530 by 243, we get 2 and a remainder of 44.
Use 2 as the next digit of our solution. 
Result so far: 309585.403292
Subtract 486 from 530 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 15:
440 divided by 243 is 1 with a remainder of 197.
Write down 1 as next digit of the result. 
Result so far: 309585.4032921
Subtract 243 from 440 to get 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Advancing to step 16:
1970 divided by 243 is 8 with a remainder of 26.
Write down 8 as next digit of the result. 
Result so far: 309585.40329218
If we subtract 1944 from 1970, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final result is 309585.40329218 with a remainder of 2.6e-08.
