We look at the division of 80547503 by 343 
The aim is to understand the frequency of 343 in 80547503.

Moving on to step 1:
343 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 343

On to step 2:
When dividing 80 by 343, we get 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Include the next digit (5) from the dividend after 80, then repeat: 805 / 343

Let's proceed to step 3:
The number 343 fits into 805 2 times, leaving a remainder of 119.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 686 from 805 leaves us with 119.
Bring next digit (4) of the dividend behind the 119 and repeat the process: 1194 / 343

Let's proceed to step 4:
If we divide 1194 by 343, we get 3 and a remainder of 165.
Use 3 as the next digit of our solution. 
Result so far: 23.0
Subtract 1029 from 1194 to get 165.
Include the next digit (7) from the dividend after 165, then repeat: 1657 / 343

Advancing to step 5:
343 can be fit into 1657 4 times, resulting in a remainder of 285.
Record the quotient 4 as the next digit in the result. 
Result so far: 234.0
Subtracting 1372 from 1657 leaves us with 285.
Fetch the next digit (5) from the dividend, attach it to 285 and continue: 2855 / 343

Going ahead to step 6:
343 can be fit into 2855 8 times, resulting in a remainder of 111.
Record the quotient 8 as the next digit in the result. 
Result so far: 2348.0
Deduct 2744 from 2855 and we're left with 111.
Include the next digit (0) from the dividend after 111, then repeat: 1110 / 343

Advancing to step 7:
343 goes into 1110 3 times with a remainder of 81.
Use 3 as the next digit of our solution. 
Result so far: 23483.0
Subtract 1029 from 1110 to get 81.
Take the next digit (3) from the dividend and append it to 81, then repeat: 813 / 343

Going ahead to step 8:
343 goes into 813 2 times with a remainder of 127.
Write down 2 as next digit of the result. 
Result so far: 234832.0
If we take 686 away from 813, we end up with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Advancing to step 9:
When dividing 1270 by 343, we get 3 with a remainder of 241.
Write down 3 as next digit of the result. 
Result so far: 234832.3
If we take 1029 away from 1270, we end up with 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

On to step 10:
When dividing 2410 by 343, we get 7 with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 234832.37
Deduct 2401 from 2410 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 11:
The number 343 fits into 90 0 times, leaving a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 234832.37
If we take 0 away from 90, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 12:
When dividing 900 by 343, we get 2 with a remainder of 214.
Write down 2 as next digit of the result. 
Result so far: 234832.3702
Subtract 686 from 900 to get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Advancing to step 13:
The number 343 fits into 2140 6 times, leaving a remainder of 82.
Write down 6 as next digit of the result. 
Result so far: 234832.37026
The remainder is 82 after subtracting 2058 from 2140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 14:
The number 343 fits into 820 2 times, leaving a remainder of 134.
Record the quotient 2 as the next digit in the result. 
Result so far: 234832.370262
The remainder is 134 after subtracting 686 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Going ahead to step 15:
343 can be fit into 1340 3 times, resulting in a remainder of 311.
The next digit of our result is 3. 
Result so far: 234832.3702623
If we subtract 1029 from 1340, we get 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Step 16:
When dividing 3110 by 343, we get 9 with a remainder of 23.
Record the quotient 9 as the next digit in the result. 
Result so far: 234832.37026239
Deduct 3087 from 3110 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The final outcome is 234832.37026239, with a leftover of 2.3e-08.
