We're dividing 18506837 by 349 
The aim is to understand the frequency of 349 in 18506837.

Going ahead to step 1:
If we divide 1 by 349, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 349

Going ahead to step 2:
When dividing 18 by 349, we get 0 with a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Bring next digit (5) of the dividend behind the 18 and repeat the process: 185 / 349

Step 3:
185 divided by 349 is 0 with a remainder of 185.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 185, we get 185.
Fetch the next digit (0) from the dividend, attach it to 185 and continue: 1850 / 349

Going ahead to step 4:
1850 divided by 349 is 5 with a remainder of 105.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 1745 away from 1850, we end up with 105.
Fetch the next digit (6) from the dividend, attach it to 105 and continue: 1056 / 349

Step 5:
349 can be fit into 1056 3 times, resulting in a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 53.0
If we subtract 1047 from 1056, we get 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 349

Advancing to step 6:
349 can be fit into 98 0 times, resulting in a remainder of 98.
Use 0 as the next digit of our solution. 
Result so far: 530.0
Subtract 0 from 98 to get 98.
Bring next digit (3) of the dividend behind the 98 and repeat the process: 983 / 349

Advancing to step 7:
349 goes into 983 2 times with a remainder of 285.
Use 2 as the next digit of our solution. 
Result so far: 5302.0
If we take 698 away from 983, we end up with 285.
Include the next digit (7) from the dividend after 285, then repeat: 2857 / 349

On to step 8:
The number 349 fits into 2857 8 times, leaving a remainder of 65.
Record the quotient 8 as the next digit in the result. 
Result so far: 53028.0
The remainder is 65 after subtracting 2792 from 2857.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 9:
349 can be fit into 650 1 times, resulting in a remainder of 301.
Write down 1 as next digit of the result. 
Result so far: 53028.1
The remainder is 301 after subtracting 349 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Step 10:
The number 349 fits into 3010 8 times, leaving a remainder of 218.
Put 8 as the next digit of the answer. 
Result so far: 53028.18
If we subtract 2792 from 3010, we get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Step 11:
349 can be fit into 2180 6 times, resulting in a remainder of 86.
Record the quotient 6 as the next digit in the result. 
Result so far: 53028.186
Subtract 2094 from 2180 to get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Moving on to step 12:
When dividing 860 by 349, we get 2 with a remainder of 162.
Put 2 as the next digit of the answer. 
Result so far: 53028.1862
Deduct 698 from 860 and we're left with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Step 13:
When dividing 1620 by 349, we get 4 with a remainder of 224.
Use 4 as the next digit of our solution. 
Result so far: 53028.18624
Subtracting 1396 from 1620 leaves us with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Let's proceed to step 14:
349 goes into 2240 6 times with a remainder of 146.
Record the quotient 6 as the next digit in the result. 
Result so far: 53028.186246
If we take 2094 away from 2240, we end up with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

On to step 15:
349 can be fit into 1460 4 times, resulting in a remainder of 64.
The next digit of our result is 4. 
Result so far: 53028.1862464
If we subtract 1396 from 1460, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 16:
The number 349 fits into 640 1 times, leaving a remainder of 291.
The number 1 becomes the next digit in our result. 
Result so far: 53028.18624641
The remainder is 291 after subtracting 349 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

In conclusion, the division gives 53028.18624641 with a balance of 2.91e-07.
