63875029 ÷ 647 
The aim is to understand the frequency of 647 in 63875029.

On to step 1:
When dividing 6 by 647, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 647

Advancing to step 2:
647 can be fit into 63 0 times, resulting in a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Take the next digit (8) from the dividend and append it to 63, then repeat: 638 / 647

On to step 3:
The number 647 fits into 638 0 times, leaving a remainder of 638.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 638 to get 638.
Fetch the next digit (7) from the dividend, attach it to 638 and continue: 6387 / 647

Let's proceed to step 4:
6387 divided by 647 is 9 with a remainder of 564.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 5823 away from 6387, we end up with 564.
Grab the next digit (5) from the dividend, add it to 564, then carry on: 5645 / 647

Going ahead to step 5:
5645 divided by 647 is 8 with a remainder of 469.
The number 8 becomes the next digit in our result. 
Result so far: 98.0
Subtracting 5176 from 5645 leaves us with 469.
Grab the next digit (0) from the dividend, add it to 469, then carry on: 4690 / 647

Advancing to step 6:
647 goes into 4690 7 times with a remainder of 161.
Put 7 as the next digit of the answer. 
Result so far: 987.0
Subtracting 4529 from 4690 leaves us with 161.
Fetch the next digit (2) from the dividend, attach it to 161 and continue: 1612 / 647

Let's proceed to step 7:
647 goes into 1612 2 times with a remainder of 318.
Put 2 as the next digit of the answer. 
Result so far: 9872.0
If we subtract 1294 from 1612, we get 318.
Include the next digit (9) from the dividend after 318, then repeat: 3189 / 647

Let's proceed to step 8:
If we divide 3189 by 647, we get 4 and a remainder of 601.
The number 4 becomes the next digit in our result. 
Result so far: 98724.0
If we subtract 2588 from 3189, we get 601.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6010, and continue the process.

Step 9:
The number 647 fits into 6010 9 times, leaving a remainder of 187.
Record the quotient 9 as the next digit in the result. 
Result so far: 98724.9
The remainder is 187 after subtracting 5823 from 6010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

Let's proceed to step 10:
647 can be fit into 1870 2 times, resulting in a remainder of 576.
Write down 2 as next digit of the result. 
Result so far: 98724.92
Deduct 1294 from 1870 and we're left with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Moving on to step 11:
647 goes into 5760 8 times with a remainder of 584.
The number 8 becomes the next digit in our result. 
Result so far: 98724.928
Subtract 5176 from 5760 to get 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Going ahead to step 12:
The number 647 fits into 5840 9 times, leaving a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 98724.9289
If we subtract 5823 from 5840, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 13:
The number 647 fits into 170 0 times, leaving a remainder of 170.
Use 0 as the next digit of our solution. 
Result so far: 98724.9289
If we subtract 0 from 170, we get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

On to step 14:
647 goes into 1700 2 times with a remainder of 406.
Write down 2 as next digit of the result. 
Result so far: 98724.928902
The remainder is 406 after subtracting 1294 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Let's proceed to step 15:
If we divide 4060 by 647, we get 6 and a remainder of 178.
The number 6 becomes the next digit in our result. 
Result so far: 98724.9289026
Subtracting 3882 from 4060 leaves us with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

On to step 16:
When dividing 1780 by 647, we get 2 with a remainder of 486.
Write down 2 as next digit of the result. 
Result so far: 98724.92890262
Deduct 1294 from 1780 and we're left with 486.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4860, and continue the process.

In conclusion, the division gives 98724.92890262 with a balance of 4.86e-07.
