83096230 divided by 243 
The aim is to understand the frequency of 243 in 83096230.

Step 1:
8 divided by 243 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 243

On to step 2:
If we divide 83 by 243, we get 0 and a remainder of 83.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 83 leaves us with 83.
Grab the next digit (0) from the dividend, add it to 83, then carry on: 830 / 243

Advancing to step 3:
243 goes into 830 3 times with a remainder of 101.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 729 from 830 and we're left with 101.
Bring next digit (9) of the dividend behind the 101 and repeat the process: 1019 / 243

Step 4:
243 can be fit into 1019 4 times, resulting in a remainder of 47.
Put 4 as the next digit of the answer. 
Result so far: 34.0
If we subtract 972 from 1019, we get 47.
Take the next digit (6) from the dividend and append it to 47, then repeat: 476 / 243

Moving on to step 5:
The number 243 fits into 476 1 times, leaving a remainder of 233.
The number 1 becomes the next digit in our result. 
Result so far: 341.0
If we subtract 243 from 476, we get 233.
Bring next digit (2) of the dividend behind the 233 and repeat the process: 2332 / 243

Advancing to step 6:
2332 divided by 243 is 9 with a remainder of 145.
The next digit of our result is 9. 
Result so far: 3419.0
Subtracting 2187 from 2332 leaves us with 145.
Fetch the next digit (3) from the dividend, attach it to 145 and continue: 1453 / 243

Going ahead to step 7:
243 can be fit into 1453 5 times, resulting in a remainder of 238.
Use 5 as the next digit of our solution. 
Result so far: 34195.0
Subtracting 1215 from 1453 leaves us with 238.
Fetch the next digit (0) from the dividend, attach it to 238 and continue: 2380 / 243

On to step 8:
When dividing 2380 by 243, we get 9 with a remainder of 193.
The number 9 becomes the next digit in our result. 
Result so far: 341959.0
If we subtract 2187 from 2380, we get 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Advancing to step 9:
243 goes into 1930 7 times with a remainder of 229.
Record the quotient 7 as the next digit in the result. 
Result so far: 341959.7
The remainder is 229 after subtracting 1701 from 1930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Going ahead to step 10:
When dividing 2290 by 243, we get 9 with a remainder of 103.
The number 9 becomes the next digit in our result. 
Result so far: 341959.79
Subtracting 2187 from 2290 leaves us with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Moving on to step 11:
The number 243 fits into 1030 4 times, leaving a remainder of 58.
Use 4 as the next digit of our solution. 
Result so far: 341959.794
Deduct 972 from 1030 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 12:
If we divide 580 by 243, we get 2 and a remainder of 94.
Use 2 as the next digit of our solution. 
Result so far: 341959.7942
The remainder is 94 after subtracting 486 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

On to step 13:
When dividing 940 by 243, we get 3 with a remainder of 211.
Write down 3 as next digit of the result. 
Result so far: 341959.79423
Subtracting 729 from 940 leaves us with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Step 14:
2110 divided by 243 is 8 with a remainder of 166.
The next digit of our result is 8. 
Result so far: 341959.794238
Subtracting 1944 from 2110 leaves us with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Let's proceed to step 15:
243 can be fit into 1660 6 times, resulting in a remainder of 202.
Put 6 as the next digit of the answer. 
Result so far: 341959.7942386
If we subtract 1458 from 1660, we get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Let's proceed to step 16:
If we divide 2020 by 243, we get 8 and a remainder of 76.
Record the quotient 8 as the next digit in the result. 
Result so far: 341959.79423868
Deduct 1944 from 2020 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final result is 341959.79423868 with a remainder of 7.6e-08.
