We're dividing 16439609 by 344 
The aim is to understand the frequency of 344 in 16439609.

Going ahead to step 1:
344 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 344

Going ahead to step 2:
16 divided by 344 is 0 with a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Fetch the next digit (4) from the dividend, attach it to 16 and continue: 164 / 344

Moving on to step 3:
344 goes into 164 0 times with a remainder of 164.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 164, we end up with 164.
Include the next digit (3) from the dividend after 164, then repeat: 1643 / 344

On to step 4:
When dividing 1643 by 344, we get 4 with a remainder of 267.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 1376 from 1643 to get 267.
Take the next digit (9) from the dividend and append it to 267, then repeat: 2679 / 344

Advancing to step 5:
The number 344 fits into 2679 7 times, leaving a remainder of 271.
Use 7 as the next digit of our solution. 
Result so far: 47.0
If we subtract 2408 from 2679, we get 271.
Append the next digit (6) from the dividend to 271 and continue with: 2716 / 344

On to step 6:
When dividing 2716 by 344, we get 7 with a remainder of 308.
Put 7 as the next digit of the answer. 
Result so far: 477.0
Deduct 2408 from 2716 and we're left with 308.
Bring next digit (0) of the dividend behind the 308 and repeat the process: 3080 / 344

Let's proceed to step 7:
If we divide 3080 by 344, we get 8 and a remainder of 328.
Put 8 as the next digit of the answer. 
Result so far: 4778.0
Subtract 2752 from 3080 to get 328.
Grab the next digit (9) from the dividend, add it to 328, then carry on: 3289 / 344

Advancing to step 8:
344 can be fit into 3289 9 times, resulting in a remainder of 193.
Put 9 as the next digit of the answer. 
Result so far: 47789.0
Subtracting 3096 from 3289 leaves us with 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Moving on to step 9:
344 can be fit into 1930 5 times, resulting in a remainder of 210.
The next digit of our result is 5. 
Result so far: 47789.5
Subtracting 1720 from 1930 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Let's proceed to step 10:
The number 344 fits into 2100 6 times, leaving a remainder of 36.
Put 6 as the next digit of the answer. 
Result so far: 47789.56
Deduct 2064 from 2100 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 11:
344 goes into 360 1 times with a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 47789.561
Subtracting 344 from 360 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 12:
344 can be fit into 160 0 times, resulting in a remainder of 160.
Record the quotient 0 as the next digit in the result. 
Result so far: 47789.561
The remainder is 160 after subtracting 0 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 13:
When dividing 1600 by 344, we get 4 with a remainder of 224.
Put 4 as the next digit of the answer. 
Result so far: 47789.56104
Subtract 1376 from 1600 to get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Moving on to step 14:
344 can be fit into 2240 6 times, resulting in a remainder of 176.
Use 6 as the next digit of our solution. 
Result so far: 47789.561046
Deduct 2064 from 2240 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Step 15:
344 goes into 1760 5 times with a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 47789.5610465
Deduct 1720 from 1760 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 16:
When dividing 400 by 344, we get 1 with a remainder of 56.
The number 1 becomes the next digit in our result. 
Result so far: 47789.56104651
Subtract 344 from 400 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

After the division, we end up with 47789.56104651 and a remainder of 5.6e-08.
