We look at the division of 73280925 by 344 
The aim is to understand the frequency of 344 in 73280925.

On to step 1:
If we divide 7 by 344, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 344

Going ahead to step 2:
344 goes into 73 0 times with a remainder of 73.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 73, we end up with 73.
Include the next digit (2) from the dividend after 73, then repeat: 732 / 344

Step 3:
When dividing 732 by 344, we get 2 with a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 688 from 732, we get 44.
Take the next digit (8) from the dividend and append it to 44, then repeat: 448 / 344

On to step 4:
448 divided by 344 is 1 with a remainder of 104.
Use 1 as the next digit of our solution. 
Result so far: 21.0
If we subtract 344 from 448, we get 104.
Include the next digit (0) from the dividend after 104, then repeat: 1040 / 344

Let's proceed to step 5:
344 can be fit into 1040 3 times, resulting in a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 213.0
If we subtract 1032 from 1040, we get 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 344

Moving on to step 6:
89 divided by 344 is 0 with a remainder of 89.
Use 0 as the next digit of our solution. 
Result so far: 2130.0
If we take 0 away from 89, we end up with 89.
Fetch the next digit (2) from the dividend, attach it to 89 and continue: 892 / 344

Moving on to step 7:
If we divide 892 by 344, we get 2 and a remainder of 204.
The next digit of our result is 2. 
Result so far: 21302.0
Subtracting 688 from 892 leaves us with 204.
Bring next digit (5) of the dividend behind the 204 and repeat the process: 2045 / 344

Advancing to step 8:
344 can be fit into 2045 5 times, resulting in a remainder of 325.
The next digit of our result is 5. 
Result so far: 213025.0
Subtract 1720 from 2045 to get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Advancing to step 9:
344 can be fit into 3250 9 times, resulting in a remainder of 154.
Write down 9 as next digit of the result. 
Result so far: 213025.9
Deduct 3096 from 3250 and we're left with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

On to step 10:
344 can be fit into 1540 4 times, resulting in a remainder of 164.
The next digit of our result is 4. 
Result so far: 213025.94
Subtract 1376 from 1540 to get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Advancing to step 11:
344 can be fit into 1640 4 times, resulting in a remainder of 264.
The number 4 becomes the next digit in our result. 
Result so far: 213025.944
The remainder is 264 after subtracting 1376 from 1640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Our division results in 213025.944 with a remaining 0.0264.
