We look at the division of 6463254 by 729 
The aim is to understand the frequency of 729 in 6463254.

Step 1:
The number 729 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 729

On to step 2:
729 can be fit into 64 0 times, resulting in a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Grab the next digit (6) from the dividend, add it to 64, then carry on: 646 / 729

Advancing to step 3:
729 goes into 646 0 times with a remainder of 646.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 646 and we're left with 646.
Fetch the next digit (3) from the dividend, attach it to 646 and continue: 6463 / 729

Step 4:
729 goes into 6463 8 times with a remainder of 631.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 5832 from 6463, we get 631.
Include the next digit (2) from the dividend after 631, then repeat: 6312 / 729

Let's proceed to step 5:
729 goes into 6312 8 times with a remainder of 480.
Write down 8 as next digit of the result. 
Result so far: 88.0
Subtracting 5832 from 6312 leaves us with 480.
Grab the next digit (5) from the dividend, add it to 480, then carry on: 4805 / 729

Advancing to step 6:
729 can be fit into 4805 6 times, resulting in a remainder of 431.
Use 6 as the next digit of our solution. 
Result so far: 886.0
If we take 4374 away from 4805, we end up with 431.
Take the next digit (4) from the dividend and append it to 431, then repeat: 4314 / 729

Advancing to step 7:
The number 729 fits into 4314 5 times, leaving a remainder of 669.
Put 5 as the next digit of the answer. 
Result so far: 8865.0
Subtracting 3645 from 4314 leaves us with 669.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6690, and continue the process.

Moving on to step 8:
729 goes into 6690 9 times with a remainder of 129.
Record the quotient 9 as the next digit in the result. 
Result so far: 8865.9
Subtract 6561 from 6690 to get 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Let's proceed to step 9:
If we divide 1290 by 729, we get 1 and a remainder of 561.
The next digit of our result is 1. 
Result so far: 8865.91
If we subtract 729 from 1290, we get 561.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5610, and continue the process.

On to step 10:
If we divide 5610 by 729, we get 7 and a remainder of 507.
The number 7 becomes the next digit in our result. 
Result so far: 8865.917
The remainder is 507 after subtracting 5103 from 5610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5070, and continue the process.

On to step 11:
729 can be fit into 5070 6 times, resulting in a remainder of 696.
Record the quotient 6 as the next digit in the result. 
Result so far: 8865.9176
If we take 4374 away from 5070, we end up with 696.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

Advancing to step 12:
When dividing 6960 by 729, we get 9 with a remainder of 399.
Use 9 as the next digit of our solution. 
Result so far: 8865.91769
If we take 6561 away from 6960, we end up with 399.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

Advancing to step 13:
3990 divided by 729 is 5 with a remainder of 345.
Record the quotient 5 as the next digit in the result. 
Result so far: 8865.917695
If we subtract 3645 from 3990, we get 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Step 14:
If we divide 3450 by 729, we get 4 and a remainder of 534.
Put 4 as the next digit of the answer. 
Result so far: 8865.9176954
If we subtract 2916 from 3450, we get 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Advancing to step 15:
729 goes into 5340 7 times with a remainder of 237.
The next digit of our result is 7. 
Result so far: 8865.91769547
Subtract 5103 from 5340 to get 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Our division results in 8865.91769547 with a remaining 2.37e-07.
