57854386 ÷ 343 
The aim is to understand the frequency of 343 in 57854386.

Advancing to step 1:
5 divided by 343 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 343

Let's proceed to step 2:
The number 343 fits into 57 0 times, leaving a remainder of 57.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 57, we end up with 57.
Fetch the next digit (8) from the dividend, attach it to 57 and continue: 578 / 343

Advancing to step 3:
If we divide 578 by 343, we get 1 and a remainder of 235.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 343 from 578 to get 235.
Fetch the next digit (5) from the dividend, attach it to 235 and continue: 2355 / 343

Step 4:
2355 divided by 343 is 6 with a remainder of 297.
The next digit of our result is 6. 
Result so far: 16.0
The remainder is 297 after subtracting 2058 from 2355.
Grab the next digit (4) from the dividend, add it to 297, then carry on: 2974 / 343

On to step 5:
The number 343 fits into 2974 8 times, leaving a remainder of 230.
Use 8 as the next digit of our solution. 
Result so far: 168.0
Deduct 2744 from 2974 and we're left with 230.
Include the next digit (3) from the dividend after 230, then repeat: 2303 / 343

Going ahead to step 6:
When dividing 2303 by 343, we get 6 with a remainder of 245.
The next digit of our result is 6. 
Result so far: 1686.0
The remainder is 245 after subtracting 2058 from 2303.
Fetch the next digit (8) from the dividend, attach it to 245 and continue: 2458 / 343

Let's proceed to step 7:
343 can be fit into 2458 7 times, resulting in a remainder of 57.
Use 7 as the next digit of our solution. 
Result so far: 16867.0
Deduct 2401 from 2458 and we're left with 57.
Grab the next digit (6) from the dividend, add it to 57, then carry on: 576 / 343

Advancing to step 8:
576 divided by 343 is 1 with a remainder of 233.
Write down 1 as next digit of the result. 
Result so far: 168671.0
Subtract 343 from 576 to get 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Let's proceed to step 9:
When dividing 2330 by 343, we get 6 with a remainder of 272.
Use 6 as the next digit of our solution. 
Result so far: 168671.6
The remainder is 272 after subtracting 2058 from 2330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Moving on to step 10:
If we divide 2720 by 343, we get 7 and a remainder of 319.
Record the quotient 7 as the next digit in the result. 
Result so far: 168671.67
The remainder is 319 after subtracting 2401 from 2720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Step 11:
343 can be fit into 3190 9 times, resulting in a remainder of 103.
The number 9 becomes the next digit in our result. 
Result so far: 168671.679
Subtract 3087 from 3190 to get 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 12:
The number 343 fits into 1030 3 times, leaving a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 168671.6793
If we subtract 1029 from 1030, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 13:
343 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 168671.6793
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 14:
343 can be fit into 100 0 times, resulting in a remainder of 100.
The next digit of our result is 0. 
Result so far: 168671.6793
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final result is 168671.6793 with a remainder of 1e-05.
