We're dividing 21344089 by 725 
The aim is to understand the frequency of 725 in 21344089.

On to step 1:
2 divided by 725 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 725

Moving on to step 2:
725 can be fit into 21 0 times, resulting in a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Take the next digit (3) from the dividend and append it to 21, then repeat: 213 / 725

Let's proceed to step 3:
When dividing 213 by 725, we get 0 with a remainder of 213.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 213 and we're left with 213.
Append the next digit (4) from the dividend to 213 and continue with: 2134 / 725

Advancing to step 4:
725 goes into 2134 2 times with a remainder of 684.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 1450 from 2134, we get 684.
Append the next digit (4) from the dividend to 684 and continue with: 6844 / 725

Step 5:
725 goes into 6844 9 times with a remainder of 319.
Put 9 as the next digit of the answer. 
Result so far: 29.0
Deduct 6525 from 6844 and we're left with 319.
Bring next digit (0) of the dividend behind the 319 and repeat the process: 3190 / 725

Moving on to step 6:
The number 725 fits into 3190 4 times, leaving a remainder of 290.
Record the quotient 4 as the next digit in the result. 
Result so far: 294.0
Subtract 2900 from 3190 to get 290.
Take the next digit (8) from the dividend and append it to 290, then repeat: 2908 / 725

Step 7:
When dividing 2908 by 725, we get 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 2944.0
The remainder is 8 after subtracting 2900 from 2908.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 725

Going ahead to step 8:
89 divided by 725 is 0 with a remainder of 89.
Record the quotient 0 as the next digit in the result. 
Result so far: 29440.0
Subtract 0 from 89 to get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

On to step 9:
890 divided by 725 is 1 with a remainder of 165.
The number 1 becomes the next digit in our result. 
Result so far: 29440.1
The remainder is 165 after subtracting 725 from 890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Going ahead to step 10:
725 can be fit into 1650 2 times, resulting in a remainder of 200.
The next digit of our result is 2. 
Result so far: 29440.12
The remainder is 200 after subtracting 1450 from 1650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 11:
725 goes into 2000 2 times with a remainder of 550.
The next digit of our result is 2. 
Result so far: 29440.122
Subtracting 1450 from 2000 leaves us with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

After the division, we end up with 29440.122 and a remainder of 0.055.
