Let's divide 3297087 by 349
The aim is to understand the frequency of 349 in 3297087.

Going ahead to step 1:
If we divide 3 by 349, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 349

Step 2:
The number 349 fits into 32 0 times, leaving a remainder of 32.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 32 to get 32.
Append the next digit (9) from the dividend to 32 and continue with: 329 / 349

Advancing to step 3:
If we divide 329 by 349, we get 0 and a remainder of 329.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 329 to get 329.
Include the next digit (7) from the dividend after 329, then repeat: 3297 / 349

Going ahead to step 4:
If we divide 3297 by 349, we get 9 and a remainder of 156.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtract 3141 from 3297 to get 156.
Append the next digit (0) from the dividend to 156 and continue with: 1560 / 349

Moving on to step 5:
If we divide 1560 by 349, we get 4 and a remainder of 164.
Use 4 as the next digit of our solution. 
Result so far: 94.0
If we subtract 1396 from 1560, we get 164.
Include the next digit (8) from the dividend after 164, then repeat: 1648 / 349

Moving on to step 6:
349 goes into 1648 4 times with a remainder of 252.
Put 4 as the next digit of the answer. 
Result so far: 944.0
Subtracting 1396 from 1648 leaves us with 252.
Include the next digit (7) from the dividend after 252, then repeat: 2527 / 349

Step 7:
If we divide 2527 by 349, we get 7 and a remainder of 84.
Put 7 as the next digit of the answer. 
Result so far: 9447.0
Subtracting 2443 from 2527 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 8:
349 can be fit into 840 2 times, resulting in a remainder of 142.
Put 2 as the next digit of the answer. 
Result so far: 9447.2
Subtracting 698 from 840 leaves us with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Moving on to step 9:
If we divide 1420 by 349, we get 4 and a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 9447.24
Deduct 1396 from 1420 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 10:
The number 349 fits into 240 0 times, leaving a remainder of 240.
The next digit of our result is 0. 
Result so far: 9447.24
If we subtract 0 from 240, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Going ahead to step 11:
2400 divided by 349 is 6 with a remainder of 306.
Put 6 as the next digit of the answer. 
Result so far: 9447.2406
The remainder is 306 after subtracting 2094 from 2400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Step 12:
If we divide 3060 by 349, we get 8 and a remainder of 268.
The next digit of our result is 8. 
Result so far: 9447.24068
If we subtract 2792 from 3060, we get 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Going ahead to step 13:
If we divide 2680 by 349, we get 7 and a remainder of 237.
Record the quotient 7 as the next digit in the result. 
Result so far: 9447.240687
Subtracting 2443 from 2680 leaves us with 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Step 14:
When dividing 2370 by 349, we get 6 with a remainder of 276.
Record the quotient 6 as the next digit in the result. 
Result so far: 9447.2406876
The remainder is 276 after subtracting 2094 from 2370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Advancing to step 15:
349 can be fit into 2760 7 times, resulting in a remainder of 317.
The next digit of our result is 7. 
Result so far: 9447.24068767
If we take 2443 away from 2760, we end up with 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

The final result is 9447.24068767 with a remainder of 3.17e-07.
