We look at the division of 46353028 by 729 
The aim is to understand the frequency of 729 in 46353028.

Going ahead to step 1:
If we divide 4 by 729, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 729

Step 2:
The number 729 fits into 46 0 times, leaving a remainder of 46.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 46, we end up with 46.
Grab the next digit (3) from the dividend, add it to 46, then carry on: 463 / 729

Step 3:
463 divided by 729 is 0 with a remainder of 463.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 463 to get 463.
Include the next digit (5) from the dividend after 463, then repeat: 4635 / 729

Step 4:
The number 729 fits into 4635 6 times, leaving a remainder of 261.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 4374 from 4635, we get 261.
Fetch the next digit (3) from the dividend, attach it to 261 and continue: 2613 / 729

On to step 5:
2613 divided by 729 is 3 with a remainder of 426.
The number 3 becomes the next digit in our result. 
Result so far: 63.0
Subtract 2187 from 2613 to get 426.
Append the next digit (0) from the dividend to 426 and continue with: 4260 / 729

Step 6:
729 goes into 4260 5 times with a remainder of 615.
The next digit of our result is 5. 
Result so far: 635.0
If we take 3645 away from 4260, we end up with 615.
Bring next digit (2) of the dividend behind the 615 and repeat the process: 6152 / 729

On to step 7:
The number 729 fits into 6152 8 times, leaving a remainder of 320.
Use 8 as the next digit of our solution. 
Result so far: 6358.0
The remainder is 320 after subtracting 5832 from 6152.
Append the next digit (8) from the dividend to 320 and continue with: 3208 / 729

Let's proceed to step 8:
729 can be fit into 3208 4 times, resulting in a remainder of 292.
Put 4 as the next digit of the answer. 
Result so far: 63584.0
The remainder is 292 after subtracting 2916 from 3208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Moving on to step 9:
2920 divided by 729 is 4 with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 63584.4
Subtract 2916 from 2920 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
729 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 63584.4
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 11:
If we divide 400 by 729, we get 0 and a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 63584.4
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

After the division, we end up with 63584.4 and a remainder of 0.04.
