71964699 ÷ 648 
The aim is to understand the frequency of 648 in 71964699.

Advancing to step 1:
648 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 648

Let's proceed to step 2:
648 can be fit into 71 0 times, resulting in a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 71, we end up with 71.
Append the next digit (9) from the dividend to 71 and continue with: 719 / 648

Advancing to step 3:
719 divided by 648 is 1 with a remainder of 71.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 648 from 719 and we're left with 71.
Take the next digit (6) from the dividend and append it to 71, then repeat: 716 / 648

Let's proceed to step 4:
648 can be fit into 716 1 times, resulting in a remainder of 68.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtract 648 from 716 to get 68.
Include the next digit (4) from the dividend after 68, then repeat: 684 / 648

Going ahead to step 5:
648 goes into 684 1 times with a remainder of 36.
The next digit of our result is 1. 
Result so far: 111.0
Subtract 648 from 684 to get 36.
Include the next digit (6) from the dividend after 36, then repeat: 366 / 648

Moving on to step 6:
648 goes into 366 0 times with a remainder of 366.
Put 0 as the next digit of the answer. 
Result so far: 1110.0
The remainder is 366 after subtracting 0 from 366.
Fetch the next digit (9) from the dividend, attach it to 366 and continue: 3669 / 648

Let's proceed to step 7:
If we divide 3669 by 648, we get 5 and a remainder of 429.
The next digit of our result is 5. 
Result so far: 11105.0
The remainder is 429 after subtracting 3240 from 3669.
Bring next digit (9) of the dividend behind the 429 and repeat the process: 4299 / 648

Moving on to step 8:
648 can be fit into 4299 6 times, resulting in a remainder of 411.
Put 6 as the next digit of the answer. 
Result so far: 111056.0
The remainder is 411 after subtracting 3888 from 4299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4110, and continue the process.

Going ahead to step 9:
If we divide 4110 by 648, we get 6 and a remainder of 222.
Use 6 as the next digit of our solution. 
Result so far: 111056.6
Subtracting 3888 from 4110 leaves us with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

On to step 10:
If we divide 2220 by 648, we get 3 and a remainder of 276.
The number 3 becomes the next digit in our result. 
Result so far: 111056.63
Subtracting 1944 from 2220 leaves us with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Let's proceed to step 11:
2760 divided by 648 is 4 with a remainder of 168.
Write down 4 as next digit of the result. 
Result so far: 111056.634
The remainder is 168 after subtracting 2592 from 2760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Going ahead to step 12:
If we divide 1680 by 648, we get 2 and a remainder of 384.
Use 2 as the next digit of our solution. 
Result so far: 111056.6342
If we subtract 1296 from 1680, we get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Advancing to step 13:
When dividing 3840 by 648, we get 5 with a remainder of 600.
The number 5 becomes the next digit in our result. 
Result so far: 111056.63425
If we subtract 3240 from 3840, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Advancing to step 14:
6000 divided by 648 is 9 with a remainder of 168.
The number 9 becomes the next digit in our result. 
Result so far: 111056.634259
If we take 5832 away from 6000, we end up with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Moving on to step 15:
648 goes into 1680 2 times with a remainder of 384.
Record the quotient 2 as the next digit in the result. 
Result so far: 111056.6342592
If we take 1296 away from 1680, we end up with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Step 16:
3840 divided by 648 is 5 with a remainder of 600.
The number 5 becomes the next digit in our result. 
Result so far: 111056.63425925
Subtract 3240 from 3840 to get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

In conclusion, the division gives 111056.63425925 with a balance of 6e-07.
