4791523 ÷ 729 
The aim is to understand the frequency of 729 in 4791523.

Going ahead to step 1:
729 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 729

Let's proceed to step 2:
When dividing 47 by 729, we get 0 with a remainder of 47.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 47 leaves us with 47.
Append the next digit (9) from the dividend to 47 and continue with: 479 / 729

Going ahead to step 3:
479 divided by 729 is 0 with a remainder of 479.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 479, we get 479.
Include the next digit (1) from the dividend after 479, then repeat: 4791 / 729

On to step 4:
If we divide 4791 by 729, we get 6 and a remainder of 417.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 4374 from 4791 to get 417.
Include the next digit (5) from the dividend after 417, then repeat: 4175 / 729

Going ahead to step 5:
729 can be fit into 4175 5 times, resulting in a remainder of 530.
The number 5 becomes the next digit in our result. 
Result so far: 65.0
If we take 3645 away from 4175, we end up with 530.
Append the next digit (2) from the dividend to 530 and continue with: 5302 / 729

Advancing to step 6:
5302 divided by 729 is 7 with a remainder of 199.
The next digit of our result is 7. 
Result so far: 657.0
Deduct 5103 from 5302 and we're left with 199.
Grab the next digit (3) from the dividend, add it to 199, then carry on: 1993 / 729

Advancing to step 7:
729 goes into 1993 2 times with a remainder of 535.
Put 2 as the next digit of the answer. 
Result so far: 6572.0
If we take 1458 away from 1993, we end up with 535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

On to step 8:
5350 divided by 729 is 7 with a remainder of 247.
The number 7 becomes the next digit in our result. 
Result so far: 6572.7
If we take 5103 away from 5350, we end up with 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Advancing to step 9:
The number 729 fits into 2470 3 times, leaving a remainder of 283.
Put 3 as the next digit of the answer. 
Result so far: 6572.73
Subtracting 2187 from 2470 leaves us with 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Going ahead to step 10:
If we divide 2830 by 729, we get 3 and a remainder of 643.
The number 3 becomes the next digit in our result. 
Result so far: 6572.733
The remainder is 643 after subtracting 2187 from 2830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6430, and continue the process.

The quotient of the division is 6572.733, and the remainder is 0.0643.
