Let's divide 34749920 by 349
The aim is to understand the frequency of 349 in 34749920.

Moving on to step 1:
349 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 349

Going ahead to step 2:
34 divided by 349 is 0 with a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 34 after subtracting 0 from 34.
Grab the next digit (7) from the dividend, add it to 34, then carry on: 347 / 349

Advancing to step 3:
If we divide 347 by 349, we get 0 and a remainder of 347.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 347 and we're left with 347.
Bring next digit (4) of the dividend behind the 347 and repeat the process: 3474 / 349

Step 4:
If we divide 3474 by 349, we get 9 and a remainder of 333.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 3141 from 3474, we get 333.
Fetch the next digit (9) from the dividend, attach it to 333 and continue: 3339 / 349

On to step 5:
349 can be fit into 3339 9 times, resulting in a remainder of 198.
Use 9 as the next digit of our solution. 
Result so far: 99.0
If we take 3141 away from 3339, we end up with 198.
Fetch the next digit (9) from the dividend, attach it to 198 and continue: 1989 / 349

Advancing to step 6:
The number 349 fits into 1989 5 times, leaving a remainder of 244.
The number 5 becomes the next digit in our result. 
Result so far: 995.0
If we subtract 1745 from 1989, we get 244.
Include the next digit (2) from the dividend after 244, then repeat: 2442 / 349

Let's proceed to step 7:
349 goes into 2442 6 times with a remainder of 348.
Use 6 as the next digit of our solution. 
Result so far: 9956.0
Subtract 2094 from 2442 to get 348.
Take the next digit (0) from the dividend and append it to 348, then repeat: 3480 / 349

Let's proceed to step 8:
3480 divided by 349 is 9 with a remainder of 339.
Write down 9 as next digit of the result. 
Result so far: 99569.0
The remainder is 339 after subtracting 3141 from 3480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3390, and continue the process.

On to step 9:
349 goes into 3390 9 times with a remainder of 249.
Put 9 as the next digit of the answer. 
Result so far: 99569.9
Deduct 3141 from 3390 and we're left with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Advancing to step 10:
349 goes into 2490 7 times with a remainder of 47.
Write down 7 as next digit of the result. 
Result so far: 99569.97
If we take 2443 away from 2490, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 11:
349 goes into 470 1 times with a remainder of 121.
Put 1 as the next digit of the answer. 
Result so far: 99569.971
Subtracting 349 from 470 leaves us with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

On to step 12:
If we divide 1210 by 349, we get 3 and a remainder of 163.
Use 3 as the next digit of our solution. 
Result so far: 99569.9713
If we subtract 1047 from 1210, we get 163.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1630, and continue the process.

Going ahead to step 13:
349 can be fit into 1630 4 times, resulting in a remainder of 234.
Put 4 as the next digit of the answer. 
Result so far: 99569.97134
Subtracting 1396 from 1630 leaves us with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Advancing to step 14:
The number 349 fits into 2340 6 times, leaving a remainder of 246.
Record the quotient 6 as the next digit in the result. 
Result so far: 99569.971346
If we subtract 2094 from 2340, we get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Let's proceed to step 15:
349 can be fit into 2460 7 times, resulting in a remainder of 17.
The next digit of our result is 7. 
Result so far: 99569.9713467
If we subtract 2443 from 2460, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 16:
If we divide 170 by 349, we get 0 and a remainder of 170.
The next digit of our result is 0. 
Result so far: 99569.9713467
If we subtract 0 from 170, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

In conclusion, the division gives 99569.9713467 with a balance of 1.7e-07.
