We divide 64421671 by 343
The aim is to understand the frequency of 343 in 64421671.

Let's proceed to step 1:
6 divided by 343 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 343

Moving on to step 2:
343 goes into 64 0 times with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Include the next digit (4) from the dividend after 64, then repeat: 644 / 343

Let's proceed to step 3:
If we divide 644 by 343, we get 1 and a remainder of 301.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 343 from 644 to get 301.
Take the next digit (2) from the dividend and append it to 301, then repeat: 3012 / 343

Moving on to step 4:
343 goes into 3012 8 times with a remainder of 268.
Write down 8 as next digit of the result. 
Result so far: 18.0
If we subtract 2744 from 3012, we get 268.
Fetch the next digit (1) from the dividend, attach it to 268 and continue: 2681 / 343

Step 5:
343 can be fit into 2681 7 times, resulting in a remainder of 280.
The next digit of our result is 7. 
Result so far: 187.0
Subtracting 2401 from 2681 leaves us with 280.
Take the next digit (6) from the dividend and append it to 280, then repeat: 2806 / 343

Moving on to step 6:
When dividing 2806 by 343, we get 8 with a remainder of 62.
Write down 8 as next digit of the result. 
Result so far: 1878.0
If we take 2744 away from 2806, we end up with 62.
Include the next digit (7) from the dividend after 62, then repeat: 627 / 343

Going ahead to step 7:
343 goes into 627 1 times with a remainder of 284.
The number 1 becomes the next digit in our result. 
Result so far: 18781.0
If we take 343 away from 627, we end up with 284.
Take the next digit (1) from the dividend and append it to 284, then repeat: 2841 / 343

On to step 8:
If we divide 2841 by 343, we get 8 and a remainder of 97.
Use 8 as the next digit of our solution. 
Result so far: 187818.0
Subtract 2744 from 2841 to get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Going ahead to step 9:
343 goes into 970 2 times with a remainder of 284.
The next digit of our result is 2. 
Result so far: 187818.2
The remainder is 284 after subtracting 686 from 970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

On to step 10:
343 can be fit into 2840 8 times, resulting in a remainder of 96.
Use 8 as the next digit of our solution. 
Result so far: 187818.28
The remainder is 96 after subtracting 2744 from 2840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 11:
When dividing 960 by 343, we get 2 with a remainder of 274.
Write down 2 as next digit of the result. 
Result so far: 187818.282
Deduct 686 from 960 and we're left with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

On to step 12:
The number 343 fits into 2740 7 times, leaving a remainder of 339.
The next digit of our result is 7. 
Result so far: 187818.2827
If we take 2401 away from 2740, we end up with 339.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

Going ahead to step 13:
When dividing 3390 by 343, we get 9 with a remainder of 303.
Use 9 as the next digit of our solution. 
Result so far: 187818.28279
If we subtract 3087 from 3390, we get 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

Advancing to step 14:
343 goes into 3030 8 times with a remainder of 286.
The next digit of our result is 8. 
Result so far: 187818.282798
If we subtract 2744 from 3030, we get 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Moving on to step 15:
343 can be fit into 2860 8 times, resulting in a remainder of 116.
Put 8 as the next digit of the answer. 
Result so far: 187818.2827988
If we subtract 2744 from 2860, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

The final outcome is 187818.2827988, with a leftover of 1.16e-06.
