We look at the division of 70304883 by 729 
The aim is to understand the frequency of 729 in 70304883.

Let's proceed to step 1:
When dividing 7 by 729, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 729

Step 2:
When dividing 70 by 729, we get 0 with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 70 and we're left with 70.
Append the next digit (3) from the dividend to 70 and continue with: 703 / 729

Advancing to step 3:
The number 729 fits into 703 0 times, leaving a remainder of 703.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 703, we get 703.
Take the next digit (0) from the dividend and append it to 703, then repeat: 7030 / 729

Advancing to step 4:
When dividing 7030 by 729, we get 9 with a remainder of 469.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 6561 from 7030 to get 469.
Bring next digit (4) of the dividend behind the 469 and repeat the process: 4694 / 729

Going ahead to step 5:
729 goes into 4694 6 times with a remainder of 320.
Use 6 as the next digit of our solution. 
Result so far: 96.0
Subtract 4374 from 4694 to get 320.
Include the next digit (8) from the dividend after 320, then repeat: 3208 / 729

Advancing to step 6:
729 goes into 3208 4 times with a remainder of 292.
Use 4 as the next digit of our solution. 
Result so far: 964.0
If we subtract 2916 from 3208, we get 292.
Grab the next digit (8) from the dividend, add it to 292, then carry on: 2928 / 729

Let's proceed to step 7:
729 goes into 2928 4 times with a remainder of 12.
The next digit of our result is 4. 
Result so far: 9644.0
Subtracting 2916 from 2928 leaves us with 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 729

Moving on to step 8:
The number 729 fits into 123 0 times, leaving a remainder of 123.
Use 0 as the next digit of our solution. 
Result so far: 96440.0
If we subtract 0 from 123, we get 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Moving on to step 9:
729 can be fit into 1230 1 times, resulting in a remainder of 501.
The next digit of our result is 1. 
Result so far: 96440.1
Subtract 729 from 1230 to get 501.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5010, and continue the process.

Advancing to step 10:
If we divide 5010 by 729, we get 6 and a remainder of 636.
Record the quotient 6 as the next digit in the result. 
Result so far: 96440.16
Deduct 4374 from 5010 and we're left with 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Going ahead to step 11:
6360 divided by 729 is 8 with a remainder of 528.
Write down 8 as next digit of the result. 
Result so far: 96440.168
Deduct 5832 from 6360 and we're left with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

On to step 12:
729 goes into 5280 7 times with a remainder of 177.
The number 7 becomes the next digit in our result. 
Result so far: 96440.1687
If we subtract 5103 from 5280, we get 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Moving on to step 13:
729 can be fit into 1770 2 times, resulting in a remainder of 312.
Use 2 as the next digit of our solution. 
Result so far: 96440.16872
If we subtract 1458 from 1770, we get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

On to step 14:
3120 divided by 729 is 4 with a remainder of 204.
Use 4 as the next digit of our solution. 
Result so far: 96440.168724
Deduct 2916 from 3120 and we're left with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Step 15:
729 can be fit into 2040 2 times, resulting in a remainder of 582.
The number 2 becomes the next digit in our result. 
Result so far: 96440.1687242
Deduct 1458 from 2040 and we're left with 582.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5820, and continue the process.

Step 16:
729 can be fit into 5820 7 times, resulting in a remainder of 717.
Put 7 as the next digit of the answer. 
Result so far: 96440.16872427
Subtracting 5103 from 5820 leaves us with 717.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7170, and continue the process.

After the division, we end up with 96440.16872427 and a remainder of 7.17e-07.
