96450039 divided by 343 
The aim is to understand the frequency of 343 in 96450039.

Moving on to step 1:
If we divide 9 by 343, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 343

Moving on to step 2:
When dividing 96 by 343, we get 0 with a remainder of 96.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 96 after subtracting 0 from 96.
Take the next digit (4) from the dividend and append it to 96, then repeat: 964 / 343

Advancing to step 3:
343 can be fit into 964 2 times, resulting in a remainder of 278.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 686 away from 964, we end up with 278.
Take the next digit (5) from the dividend and append it to 278, then repeat: 2785 / 343

Let's proceed to step 4:
The number 343 fits into 2785 8 times, leaving a remainder of 41.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
If we subtract 2744 from 2785, we get 41.
Fetch the next digit (0) from the dividend, attach it to 41 and continue: 410 / 343

Moving on to step 5:
343 goes into 410 1 times with a remainder of 67.
Record the quotient 1 as the next digit in the result. 
Result so far: 281.0
Deduct 343 from 410 and we're left with 67.
Grab the next digit (0) from the dividend, add it to 67, then carry on: 670 / 343

Let's proceed to step 6:
343 goes into 670 1 times with a remainder of 327.
The next digit of our result is 1. 
Result so far: 2811.0
The remainder is 327 after subtracting 343 from 670.
Grab the next digit (3) from the dividend, add it to 327, then carry on: 3273 / 343

Let's proceed to step 7:
3273 divided by 343 is 9 with a remainder of 186.
Use 9 as the next digit of our solution. 
Result so far: 28119.0
Deduct 3087 from 3273 and we're left with 186.
Include the next digit (9) from the dividend after 186, then repeat: 1869 / 343

Step 8:
The number 343 fits into 1869 5 times, leaving a remainder of 154.
Record the quotient 5 as the next digit in the result. 
Result so far: 281195.0
The remainder is 154 after subtracting 1715 from 1869.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Let's proceed to step 9:
When dividing 1540 by 343, we get 4 with a remainder of 168.
The next digit of our result is 4. 
Result so far: 281195.4
If we subtract 1372 from 1540, we get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Advancing to step 10:
The number 343 fits into 1680 4 times, leaving a remainder of 308.
Put 4 as the next digit of the answer. 
Result so far: 281195.44
If we subtract 1372 from 1680, we get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

The final result is 281195.44 with a remainder of 0.308.
