We look at the division of 13268450 by 344 
The aim is to understand the frequency of 344 in 13268450.

Moving on to step 1:
The number 344 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 344

Moving on to step 2:
344 goes into 13 0 times with a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Take the next digit (2) from the dividend and append it to 13, then repeat: 132 / 344

Going ahead to step 3:
344 goes into 132 0 times with a remainder of 132.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 132 leaves us with 132.
Grab the next digit (6) from the dividend, add it to 132, then carry on: 1326 / 344

Let's proceed to step 4:
If we divide 1326 by 344, we get 3 and a remainder of 294.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 1032 away from 1326, we end up with 294.
Grab the next digit (8) from the dividend, add it to 294, then carry on: 2948 / 344

Advancing to step 5:
2948 divided by 344 is 8 with a remainder of 196.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
If we take 2752 away from 2948, we end up with 196.
Fetch the next digit (4) from the dividend, attach it to 196 and continue: 1964 / 344

Going ahead to step 6:
When dividing 1964 by 344, we get 5 with a remainder of 244.
The number 5 becomes the next digit in our result. 
Result so far: 385.0
Deduct 1720 from 1964 and we're left with 244.
Grab the next digit (5) from the dividend, add it to 244, then carry on: 2445 / 344

Let's proceed to step 7:
If we divide 2445 by 344, we get 7 and a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 3857.0
If we take 2408 away from 2445, we end up with 37.
Fetch the next digit (0) from the dividend, attach it to 37 and continue: 370 / 344

Going ahead to step 8:
344 can be fit into 370 1 times, resulting in a remainder of 26.
The number 1 becomes the next digit in our result. 
Result so far: 38571.0
Deduct 344 from 370 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 9:
260 divided by 344 is 0 with a remainder of 260.
The next digit of our result is 0. 
Result so far: 38571.0
The remainder is 260 after subtracting 0 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 10:
2600 divided by 344 is 7 with a remainder of 192.
Record the quotient 7 as the next digit in the result. 
Result so far: 38571.07
Subtract 2408 from 2600 to get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Advancing to step 11:
If we divide 1920 by 344, we get 5 and a remainder of 200.
The next digit of our result is 5. 
Result so far: 38571.075
If we take 1720 away from 1920, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 12:
When dividing 2000 by 344, we get 5 with a remainder of 280.
The next digit of our result is 5. 
Result so far: 38571.0755
Subtracting 1720 from 2000 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

The final result is 38571.0755 with a remainder of 0.0028.
