We divide 10304454 by 243
The aim is to understand the frequency of 243 in 10304454.

Going ahead to step 1:
243 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 243

Step 2:
10 divided by 243 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 10 and we're left with 10.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 243

Let's proceed to step 3:
If we divide 103 by 243, we get 0 and a remainder of 103.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 103, we get 103.
Take the next digit (0) from the dividend and append it to 103, then repeat: 1030 / 243

Moving on to step 4:
When dividing 1030 by 243, we get 4 with a remainder of 58.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 972 from 1030, we get 58.
Take the next digit (4) from the dividend and append it to 58, then repeat: 584 / 243

Advancing to step 5:
The number 243 fits into 584 2 times, leaving a remainder of 98.
The next digit of our result is 2. 
Result so far: 42.0
Subtracting 486 from 584 leaves us with 98.
Grab the next digit (4) from the dividend, add it to 98, then carry on: 984 / 243

Moving on to step 6:
When dividing 984 by 243, we get 4 with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 424.0
Deduct 972 from 984 and we're left with 12.
Fetch the next digit (5) from the dividend, attach it to 12 and continue: 125 / 243

Advancing to step 7:
243 can be fit into 125 0 times, resulting in a remainder of 125.
Use 0 as the next digit of our solution. 
Result so far: 4240.0
Subtracting 0 from 125 leaves us with 125.
Take the next digit (4) from the dividend and append it to 125, then repeat: 1254 / 243

Going ahead to step 8:
243 can be fit into 1254 5 times, resulting in a remainder of 39.
The next digit of our result is 5. 
Result so far: 42405.0
Subtracting 1215 from 1254 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 9:
390 divided by 243 is 1 with a remainder of 147.
Use 1 as the next digit of our solution. 
Result so far: 42405.1
If we subtract 243 from 390, we get 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Going ahead to step 10:
The number 243 fits into 1470 6 times, leaving a remainder of 12.
The next digit of our result is 6. 
Result so far: 42405.16
If we subtract 1458 from 1470, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 11:
243 goes into 120 0 times with a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 42405.16
If we subtract 0 from 120, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 12:
243 can be fit into 1200 4 times, resulting in a remainder of 228.
Write down 4 as next digit of the result. 
Result so far: 42405.1604
The remainder is 228 after subtracting 972 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Advancing to step 13:
When dividing 2280 by 243, we get 9 with a remainder of 93.
Put 9 as the next digit of the answer. 
Result so far: 42405.16049
If we take 2187 away from 2280, we end up with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

On to step 14:
243 can be fit into 930 3 times, resulting in a remainder of 201.
The next digit of our result is 3. 
Result so far: 42405.160493
If we take 729 away from 930, we end up with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Going ahead to step 15:
2010 divided by 243 is 8 with a remainder of 66.
Record the quotient 8 as the next digit in the result. 
Result so far: 42405.1604938
The remainder is 66 after subtracting 1944 from 2010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 16:
When dividing 660 by 243, we get 2 with a remainder of 174.
Put 2 as the next digit of the answer. 
Result so far: 42405.16049382
Subtracting 486 from 660 leaves us with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

The quotient of the division is 42405.16049382, and the remainder is 1.74e-07.
