We divide 84523909 by 729
The aim is to understand the frequency of 729 in 84523909.

Advancing to step 1:
The number 729 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 729

Moving on to step 2:
84 divided by 729 is 0 with a remainder of 84.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 84 after subtracting 0 from 84.
Grab the next digit (5) from the dividend, add it to 84, then carry on: 845 / 729

Advancing to step 3:
If we divide 845 by 729, we get 1 and a remainder of 116.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 729 from 845 and we're left with 116.
Include the next digit (2) from the dividend after 116, then repeat: 1162 / 729

Let's proceed to step 4:
When dividing 1162 by 729, we get 1 with a remainder of 433.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Deduct 729 from 1162 and we're left with 433.
Take the next digit (3) from the dividend and append it to 433, then repeat: 4333 / 729

On to step 5:
If we divide 4333 by 729, we get 5 and a remainder of 688.
The number 5 becomes the next digit in our result. 
Result so far: 115.0
If we take 3645 away from 4333, we end up with 688.
Bring next digit (9) of the dividend behind the 688 and repeat the process: 6889 / 729

Step 6:
729 can be fit into 6889 9 times, resulting in a remainder of 328.
The next digit of our result is 9. 
Result so far: 1159.0
The remainder is 328 after subtracting 6561 from 6889.
Fetch the next digit (0) from the dividend, attach it to 328 and continue: 3280 / 729

Going ahead to step 7:
729 can be fit into 3280 4 times, resulting in a remainder of 364.
Use 4 as the next digit of our solution. 
Result so far: 11594.0
If we take 2916 away from 3280, we end up with 364.
Fetch the next digit (9) from the dividend, attach it to 364 and continue: 3649 / 729

Advancing to step 8:
729 can be fit into 3649 5 times, resulting in a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 115945.0
Deduct 3645 from 3649 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
If we divide 40 by 729, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 115945.0
Subtracting 0 from 40 leaves us with 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 10:
400 divided by 729 is 0 with a remainder of 400.
Put 0 as the next digit of the answer. 
Result so far: 115945.0
Subtracting 0 from 400 leaves us with 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 115945.0 and a remainder of 0.4.
