29558597 divided by 648 
The aim is to understand the frequency of 648 in 29558597.

Let's proceed to step 1:
The number 648 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 648

On to step 2:
If we divide 29 by 648, we get 0 and a remainder of 29.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 29 leaves us with 29.
Take the next digit (5) from the dividend and append it to 29, then repeat: 295 / 648

Moving on to step 3:
648 goes into 295 0 times with a remainder of 295.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 295, we get 295.
Take the next digit (5) from the dividend and append it to 295, then repeat: 2955 / 648

Moving on to step 4:
648 can be fit into 2955 4 times, resulting in a remainder of 363.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 2592 from 2955 to get 363.
Bring next digit (8) of the dividend behind the 363 and repeat the process: 3638 / 648

Step 5:
When dividing 3638 by 648, we get 5 with a remainder of 398.
Put 5 as the next digit of the answer. 
Result so far: 45.0
Subtract 3240 from 3638 to get 398.
Take the next digit (5) from the dividend and append it to 398, then repeat: 3985 / 648

Step 6:
648 goes into 3985 6 times with a remainder of 97.
The number 6 becomes the next digit in our result. 
Result so far: 456.0
Subtracting 3888 from 3985 leaves us with 97.
Append the next digit (9) from the dividend to 97 and continue with: 979 / 648

Moving on to step 7:
The number 648 fits into 979 1 times, leaving a remainder of 331.
Use 1 as the next digit of our solution. 
Result so far: 4561.0
Subtract 648 from 979 to get 331.
Bring next digit (7) of the dividend behind the 331 and repeat the process: 3317 / 648

On to step 8:
3317 divided by 648 is 5 with a remainder of 77.
Record the quotient 5 as the next digit in the result. 
Result so far: 45615.0
Subtracting 3240 from 3317 leaves us with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 9:
When dividing 770 by 648, we get 1 with a remainder of 122.
Put 1 as the next digit of the answer. 
Result so far: 45615.1
Subtract 648 from 770 to get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

On to step 10:
If we divide 1220 by 648, we get 1 and a remainder of 572.
Write down 1 as next digit of the result. 
Result so far: 45615.11
Subtracting 648 from 1220 leaves us with 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

In conclusion, the division gives 45615.11 with a balance of 0.572.
