We look at the division of 31823368 by 243 
The aim is to understand the frequency of 243 in 31823368.

Step 1:
243 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 243

Moving on to step 2:
If we divide 31 by 243, we get 0 and a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Append the next digit (8) from the dividend to 31 and continue with: 318 / 243

Let's proceed to step 3:
If we divide 318 by 243, we get 1 and a remainder of 75.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 243 from 318 leaves us with 75.
Grab the next digit (2) from the dividend, add it to 75, then carry on: 752 / 243

Let's proceed to step 4:
The number 243 fits into 752 3 times, leaving a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Deduct 729 from 752 and we're left with 23.
Take the next digit (3) from the dividend and append it to 23, then repeat: 233 / 243

On to step 5:
243 goes into 233 0 times with a remainder of 233.
Put 0 as the next digit of the answer. 
Result so far: 130.0
Subtract 0 from 233 to get 233.
Grab the next digit (3) from the dividend, add it to 233, then carry on: 2333 / 243

Going ahead to step 6:
When dividing 2333 by 243, we get 9 with a remainder of 146.
Put 9 as the next digit of the answer. 
Result so far: 1309.0
If we take 2187 away from 2333, we end up with 146.
Fetch the next digit (6) from the dividend, attach it to 146 and continue: 1466 / 243

On to step 7:
The number 243 fits into 1466 6 times, leaving a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 13096.0
If we subtract 1458 from 1466, we get 8.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 243

Step 8:
If we divide 88 by 243, we get 0 and a remainder of 88.
Use 0 as the next digit of our solution. 
Result so far: 130960.0
Deduct 0 from 88 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 9:
If we divide 880 by 243, we get 3 and a remainder of 151.
Put 3 as the next digit of the answer. 
Result so far: 130960.3
Subtracting 729 from 880 leaves us with 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Step 10:
243 can be fit into 1510 6 times, resulting in a remainder of 52.
The next digit of our result is 6. 
Result so far: 130960.36
Deduct 1458 from 1510 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 11:
If we divide 520 by 243, we get 2 and a remainder of 34.
Record the quotient 2 as the next digit in the result. 
Result so far: 130960.362
Deduct 486 from 520 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 12:
The number 243 fits into 340 1 times, leaving a remainder of 97.
Write down 1 as next digit of the result. 
Result so far: 130960.3621
If we take 243 away from 340, we end up with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Advancing to step 13:
The number 243 fits into 970 3 times, leaving a remainder of 241.
Use 3 as the next digit of our solution. 
Result so far: 130960.36213
The remainder is 241 after subtracting 729 from 970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Moving on to step 14:
2410 divided by 243 is 9 with a remainder of 223.
Write down 9 as next digit of the result. 
Result so far: 130960.362139
Deduct 2187 from 2410 and we're left with 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Step 15:
When dividing 2230 by 243, we get 9 with a remainder of 43.
Use 9 as the next digit of our solution. 
Result so far: 130960.3621399
If we subtract 2187 from 2230, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

After the division, we end up with 130960.3621399 and a remainder of 4.3e-07.
