We look at the division of 26103013 by 729 
The aim is to understand the frequency of 729 in 26103013.

Let's proceed to step 1:
729 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 729

Going ahead to step 2:
729 goes into 26 0 times with a remainder of 26.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 26 after subtracting 0 from 26.
Include the next digit (1) from the dividend after 26, then repeat: 261 / 729

Advancing to step 3:
729 goes into 261 0 times with a remainder of 261.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 261 and we're left with 261.
Include the next digit (0) from the dividend after 261, then repeat: 2610 / 729

On to step 4:
If we divide 2610 by 729, we get 3 and a remainder of 423.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 2187 from 2610, we get 423.
Append the next digit (3) from the dividend to 423 and continue with: 4233 / 729

Advancing to step 5:
The number 729 fits into 4233 5 times, leaving a remainder of 588.
The next digit of our result is 5. 
Result so far: 35.0
Deduct 3645 from 4233 and we're left with 588.
Grab the next digit (0) from the dividend, add it to 588, then carry on: 5880 / 729

Step 6:
If we divide 5880 by 729, we get 8 and a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 358.0
Subtract 5832 from 5880 to get 48.
Include the next digit (1) from the dividend after 48, then repeat: 481 / 729

Let's proceed to step 7:
If we divide 481 by 729, we get 0 and a remainder of 481.
Use 0 as the next digit of our solution. 
Result so far: 3580.0
Subtracting 0 from 481 leaves us with 481.
Fetch the next digit (3) from the dividend, attach it to 481 and continue: 4813 / 729

On to step 8:
4813 divided by 729 is 6 with a remainder of 439.
Write down 6 as next digit of the result. 
Result so far: 35806.0
Subtracting 4374 from 4813 leaves us with 439.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4390, and continue the process.

Advancing to step 9:
The number 729 fits into 4390 6 times, leaving a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 35806.6
Deduct 4374 from 4390 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 10:
729 goes into 160 0 times with a remainder of 160.
Use 0 as the next digit of our solution. 
Result so far: 35806.6
If we take 0 away from 160, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 11:
When dividing 1600 by 729, we get 2 with a remainder of 142.
Record the quotient 2 as the next digit in the result. 
Result so far: 35806.602
Subtracting 1458 from 1600 leaves us with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Moving on to step 12:
729 goes into 1420 1 times with a remainder of 691.
The next digit of our result is 1. 
Result so far: 35806.6021
The remainder is 691 after subtracting 729 from 1420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6910, and continue the process.

On to step 13:
If we divide 6910 by 729, we get 9 and a remainder of 349.
Use 9 as the next digit of our solution. 
Result so far: 35806.60219
The remainder is 349 after subtracting 6561 from 6910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Going ahead to step 14:
729 can be fit into 3490 4 times, resulting in a remainder of 574.
Put 4 as the next digit of the answer. 
Result so far: 35806.602194
Subtract 2916 from 3490 to get 574.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

Step 15:
5740 divided by 729 is 7 with a remainder of 637.
The next digit of our result is 7. 
Result so far: 35806.6021947
If we subtract 5103 from 5740, we get 637.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6370, and continue the process.

Moving on to step 16:
The number 729 fits into 6370 8 times, leaving a remainder of 538.
Use 8 as the next digit of our solution. 
Result so far: 35806.60219478
Subtracting 5832 from 6370 leaves us with 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

The final outcome is 35806.60219478, with a leftover of 5.38e-07.
