7749873 ÷ 729 
The aim is to understand the frequency of 729 in 7749873.

Going ahead to step 1:
729 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 729

Step 2:
729 goes into 77 0 times with a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Bring next digit (4) of the dividend behind the 77 and repeat the process: 774 / 729

Moving on to step 3:
729 goes into 774 1 times with a remainder of 45.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 729 from 774, we get 45.
Append the next digit (9) from the dividend to 45 and continue with: 459 / 729

Moving on to step 4:
The number 729 fits into 459 0 times, leaving a remainder of 459.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 459 and we're left with 459.
Fetch the next digit (8) from the dividend, attach it to 459 and continue: 4598 / 729

Let's proceed to step 5:
The number 729 fits into 4598 6 times, leaving a remainder of 224.
The number 6 becomes the next digit in our result. 
Result so far: 106.0
If we take 4374 away from 4598, we end up with 224.
Bring next digit (7) of the dividend behind the 224 and repeat the process: 2247 / 729

Moving on to step 6:
The number 729 fits into 2247 3 times, leaving a remainder of 60.
Write down 3 as next digit of the result. 
Result so far: 1063.0
Subtracting 2187 from 2247 leaves us with 60.
Bring next digit (3) of the dividend behind the 60 and repeat the process: 603 / 729

Advancing to step 7:
603 divided by 729 is 0 with a remainder of 603.
Put 0 as the next digit of the answer. 
Result so far: 10630.0
Deduct 0 from 603 and we're left with 603.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6030, and continue the process.

Going ahead to step 8:
729 can be fit into 6030 8 times, resulting in a remainder of 198.
Write down 8 as next digit of the result. 
Result so far: 10630.8
Subtract 5832 from 6030 to get 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

On to step 9:
729 goes into 1980 2 times with a remainder of 522.
Record the quotient 2 as the next digit in the result. 
Result so far: 10630.82
Subtracting 1458 from 1980 leaves us with 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Advancing to step 10:
729 goes into 5220 7 times with a remainder of 117.
Use 7 as the next digit of our solution. 
Result so far: 10630.827
If we subtract 5103 from 5220, we get 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

On to step 11:
729 goes into 1170 1 times with a remainder of 441.
Write down 1 as next digit of the result. 
Result so far: 10630.8271
If we take 729 away from 1170, we end up with 441.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4410, and continue the process.

Step 12:
729 goes into 4410 6 times with a remainder of 36.
Use 6 as the next digit of our solution. 
Result so far: 10630.82716
If we subtract 4374 from 4410, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 13:
When dividing 360 by 729, we get 0 with a remainder of 360.
The next digit of our result is 0. 
Result so far: 10630.82716
If we subtract 0 from 360, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 14:
If we divide 3600 by 729, we get 4 and a remainder of 684.
The next digit of our result is 4. 
Result so far: 10630.8271604
Subtract 2916 from 3600 to get 684.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6840, and continue the process.

Step 15:
The number 729 fits into 6840 9 times, leaving a remainder of 279.
Use 9 as the next digit of our solution. 
Result so far: 10630.82716049
The remainder is 279 after subtracting 6561 from 6840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

The final result is 10630.82716049 with a remainder of 2.79e-07.
