6580044 divided by 349 
The aim is to understand the frequency of 349 in 6580044.

Step 1:
349 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 349

Moving on to step 2:
349 can be fit into 65 0 times, resulting in a remainder of 65.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 65, we end up with 65.
Grab the next digit (8) from the dividend, add it to 65, then carry on: 658 / 349

Going ahead to step 3:
If we divide 658 by 349, we get 1 and a remainder of 309.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 309 after subtracting 349 from 658.
Take the next digit (0) from the dividend and append it to 309, then repeat: 3090 / 349

Moving on to step 4:
3090 divided by 349 is 8 with a remainder of 298.
Write down 8 as next digit of the result. 
Result so far: 18.0
If we subtract 2792 from 3090, we get 298.
Grab the next digit (0) from the dividend, add it to 298, then carry on: 2980 / 349

Advancing to step 5:
When dividing 2980 by 349, we get 8 with a remainder of 188.
Write down 8 as next digit of the result. 
Result so far: 188.0
Deduct 2792 from 2980 and we're left with 188.
Append the next digit (4) from the dividend to 188 and continue with: 1884 / 349

Step 6:
349 can be fit into 1884 5 times, resulting in a remainder of 139.
Write down 5 as next digit of the result. 
Result so far: 1885.0
Deduct 1745 from 1884 and we're left with 139.
Grab the next digit (4) from the dividend, add it to 139, then carry on: 1394 / 349

Going ahead to step 7:
349 can be fit into 1394 3 times, resulting in a remainder of 347.
The number 3 becomes the next digit in our result. 
Result so far: 18853.0
The remainder is 347 after subtracting 1047 from 1394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

Moving on to step 8:
3470 divided by 349 is 9 with a remainder of 329.
Record the quotient 9 as the next digit in the result. 
Result so far: 18853.9
If we take 3141 away from 3470, we end up with 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Let's proceed to step 9:
349 goes into 3290 9 times with a remainder of 149.
Put 9 as the next digit of the answer. 
Result so far: 18853.99
Subtracting 3141 from 3290 leaves us with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

The final result is 18853.99 with a remainder of 0.149.
