Let's divide 64040411 by 648
The aim is to understand the frequency of 648 in 64040411.

Going ahead to step 1:
648 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 648

Advancing to step 2:
When dividing 64 by 648, we get 0 with a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Include the next digit (0) from the dividend after 64, then repeat: 640 / 648

On to step 3:
The number 648 fits into 640 0 times, leaving a remainder of 640.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 640 after subtracting 0 from 640.
Append the next digit (4) from the dividend to 640 and continue with: 6404 / 648

Moving on to step 4:
When dividing 6404 by 648, we get 9 with a remainder of 572.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 572 after subtracting 5832 from 6404.
Grab the next digit (0) from the dividend, add it to 572, then carry on: 5720 / 648

Step 5:
If we divide 5720 by 648, we get 8 and a remainder of 536.
Use 8 as the next digit of our solution. 
Result so far: 98.0
If we take 5184 away from 5720, we end up with 536.
Append the next digit (4) from the dividend to 536 and continue with: 5364 / 648

On to step 6:
When dividing 5364 by 648, we get 8 with a remainder of 180.
Write down 8 as next digit of the result. 
Result so far: 988.0
If we subtract 5184 from 5364, we get 180.
Grab the next digit (1) from the dividend, add it to 180, then carry on: 1801 / 648

Advancing to step 7:
648 can be fit into 1801 2 times, resulting in a remainder of 505.
The number 2 becomes the next digit in our result. 
Result so far: 9882.0
If we take 1296 away from 1801, we end up with 505.
Bring next digit (1) of the dividend behind the 505 and repeat the process: 5051 / 648

Advancing to step 8:
5051 divided by 648 is 7 with a remainder of 515.
Record the quotient 7 as the next digit in the result. 
Result so far: 98827.0
If we subtract 4536 from 5051, we get 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Advancing to step 9:
When dividing 5150 by 648, we get 7 with a remainder of 614.
Write down 7 as next digit of the result. 
Result so far: 98827.7
Subtracting 4536 from 5150 leaves us with 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

Moving on to step 10:
When dividing 6140 by 648, we get 9 with a remainder of 308.
The next digit of our result is 9. 
Result so far: 98827.79
The remainder is 308 after subtracting 5832 from 6140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Moving on to step 11:
648 goes into 3080 4 times with a remainder of 488.
Use 4 as the next digit of our solution. 
Result so far: 98827.794
Subtract 2592 from 3080 to get 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Let's proceed to step 12:
648 goes into 4880 7 times with a remainder of 344.
Use 7 as the next digit of our solution. 
Result so far: 98827.7947
The remainder is 344 after subtracting 4536 from 4880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Moving on to step 13:
The number 648 fits into 3440 5 times, leaving a remainder of 200.
Use 5 as the next digit of our solution. 
Result so far: 98827.79475
The remainder is 200 after subtracting 3240 from 3440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 14:
When dividing 2000 by 648, we get 3 with a remainder of 56.
Put 3 as the next digit of the answer. 
Result so far: 98827.794753
Deduct 1944 from 2000 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 15:
If we divide 560 by 648, we get 0 and a remainder of 560.
Use 0 as the next digit of our solution. 
Result so far: 98827.794753
The remainder is 560 after subtracting 0 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Step 16:
If we divide 5600 by 648, we get 8 and a remainder of 416.
Record the quotient 8 as the next digit in the result. 
Result so far: 98827.79475308
Deduct 5184 from 5600 and we're left with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

In conclusion, the division gives 98827.79475308 with a balance of 4.16e-07.
