We look at the division of 56299865 by 729 
The aim is to understand the frequency of 729 in 56299865.

Let's proceed to step 1:
When dividing 5 by 729, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 729

Moving on to step 2:
729 goes into 56 0 times with a remainder of 56.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 56, we end up with 56.
Grab the next digit (2) from the dividend, add it to 56, then carry on: 562 / 729

Advancing to step 3:
562 divided by 729 is 0 with a remainder of 562.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 562 leaves us with 562.
Fetch the next digit (9) from the dividend, attach it to 562 and continue: 5629 / 729

Advancing to step 4:
When dividing 5629 by 729, we get 7 with a remainder of 526.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 5103 away from 5629, we end up with 526.
Include the next digit (9) from the dividend after 526, then repeat: 5269 / 729

Advancing to step 5:
When dividing 5269 by 729, we get 7 with a remainder of 166.
Write down 7 as next digit of the result. 
Result so far: 77.0
Subtract 5103 from 5269 to get 166.
Fetch the next digit (8) from the dividend, attach it to 166 and continue: 1668 / 729

On to step 6:
When dividing 1668 by 729, we get 2 with a remainder of 210.
Use 2 as the next digit of our solution. 
Result so far: 772.0
The remainder is 210 after subtracting 1458 from 1668.
Fetch the next digit (6) from the dividend, attach it to 210 and continue: 2106 / 729

Going ahead to step 7:
The number 729 fits into 2106 2 times, leaving a remainder of 648.
Use 2 as the next digit of our solution. 
Result so far: 7722.0
Deduct 1458 from 2106 and we're left with 648.
Include the next digit (5) from the dividend after 648, then repeat: 6485 / 729

Advancing to step 8:
729 can be fit into 6485 8 times, resulting in a remainder of 653.
Use 8 as the next digit of our solution. 
Result so far: 77228.0
Subtracting 5832 from 6485 leaves us with 653.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6530, and continue the process.

Advancing to step 9:
When dividing 6530 by 729, we get 8 with a remainder of 698.
Write down 8 as next digit of the result. 
Result so far: 77228.8
If we subtract 5832 from 6530, we get 698.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6980, and continue the process.

Step 10:
729 can be fit into 6980 9 times, resulting in a remainder of 419.
Record the quotient 9 as the next digit in the result. 
Result so far: 77228.89
If we take 6561 away from 6980, we end up with 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

Going ahead to step 11:
4190 divided by 729 is 5 with a remainder of 545.
Put 5 as the next digit of the answer. 
Result so far: 77228.895
The remainder is 545 after subtracting 3645 from 4190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5450, and continue the process.

On to step 12:
729 goes into 5450 7 times with a remainder of 347.
The number 7 becomes the next digit in our result. 
Result so far: 77228.8957
If we subtract 5103 from 5450, we get 347.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

Advancing to step 13:
3470 divided by 729 is 4 with a remainder of 554.
Record the quotient 4 as the next digit in the result. 
Result so far: 77228.89574
If we take 2916 away from 3470, we end up with 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Going ahead to step 14:
729 can be fit into 5540 7 times, resulting in a remainder of 437.
Use 7 as the next digit of our solution. 
Result so far: 77228.895747
If we take 5103 away from 5540, we end up with 437.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

Step 15:
729 can be fit into 4370 5 times, resulting in a remainder of 725.
Use 5 as the next digit of our solution. 
Result so far: 77228.8957475
Subtract 3645 from 4370 to get 725.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7250, and continue the process.

Moving on to step 16:
The number 729 fits into 7250 9 times, leaving a remainder of 689.
The next digit of our result is 9. 
Result so far: 77228.89574759
Deduct 6561 from 7250 and we're left with 689.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6890, and continue the process.

The final outcome is 77228.89574759, with a leftover of 6.89e-07.
