38396243 ÷ 729 
The aim is to understand the frequency of 729 in 38396243.

Going ahead to step 1:
3 divided by 729 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 729

Step 2:
729 goes into 38 0 times with a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 38, we end up with 38.
Fetch the next digit (3) from the dividend, attach it to 38 and continue: 383 / 729

On to step 3:
383 divided by 729 is 0 with a remainder of 383.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 383 after subtracting 0 from 383.
Take the next digit (9) from the dividend and append it to 383, then repeat: 3839 / 729

Step 4:
When dividing 3839 by 729, we get 5 with a remainder of 194.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 3645 away from 3839, we end up with 194.
Grab the next digit (6) from the dividend, add it to 194, then carry on: 1946 / 729

Let's proceed to step 5:
When dividing 1946 by 729, we get 2 with a remainder of 488.
The number 2 becomes the next digit in our result. 
Result so far: 52.0
The remainder is 488 after subtracting 1458 from 1946.
Grab the next digit (2) from the dividend, add it to 488, then carry on: 4882 / 729

Moving on to step 6:
The number 729 fits into 4882 6 times, leaving a remainder of 508.
The number 6 becomes the next digit in our result. 
Result so far: 526.0
If we take 4374 away from 4882, we end up with 508.
Append the next digit (4) from the dividend to 508 and continue with: 5084 / 729

Let's proceed to step 7:
729 goes into 5084 6 times with a remainder of 710.
The number 6 becomes the next digit in our result. 
Result so far: 5266.0
Deduct 4374 from 5084 and we're left with 710.
Include the next digit (3) from the dividend after 710, then repeat: 7103 / 729

Step 8:
729 can be fit into 7103 9 times, resulting in a remainder of 542.
Write down 9 as next digit of the result. 
Result so far: 52669.0
Deduct 6561 from 7103 and we're left with 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

Step 9:
729 can be fit into 5420 7 times, resulting in a remainder of 317.
Use 7 as the next digit of our solution. 
Result so far: 52669.7
Subtracting 5103 from 5420 leaves us with 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Let's proceed to step 10:
729 goes into 3170 4 times with a remainder of 254.
Record the quotient 4 as the next digit in the result. 
Result so far: 52669.74
If we take 2916 away from 3170, we end up with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Step 11:
When dividing 2540 by 729, we get 3 with a remainder of 353.
Use 3 as the next digit of our solution. 
Result so far: 52669.743
Subtract 2187 from 2540 to get 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

Advancing to step 12:
If we divide 3530 by 729, we get 4 and a remainder of 614.
Use 4 as the next digit of our solution. 
Result so far: 52669.7434
If we take 2916 away from 3530, we end up with 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

On to step 13:
The number 729 fits into 6140 8 times, leaving a remainder of 308.
Write down 8 as next digit of the result. 
Result so far: 52669.74348
Subtract 5832 from 6140 to get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

On to step 14:
The number 729 fits into 3080 4 times, leaving a remainder of 164.
Write down 4 as next digit of the result. 
Result so far: 52669.743484
Subtracting 2916 from 3080 leaves us with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

On to step 15:
When dividing 1640 by 729, we get 2 with a remainder of 182.
Put 2 as the next digit of the answer. 
Result so far: 52669.7434842
Subtracting 1458 from 1640 leaves us with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Step 16:
If we divide 1820 by 729, we get 2 and a remainder of 362.
Write down 2 as next digit of the result. 
Result so far: 52669.74348422
Subtract 1458 from 1820 to get 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

After the division, we end up with 52669.74348422 and a remainder of 3.62e-07.
