58241596 divided by 728 
The aim is to understand the frequency of 728 in 58241596.

Moving on to step 1:
728 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 728

On to step 2:
728 goes into 58 0 times with a remainder of 58.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 58 to get 58.
Include the next digit (2) from the dividend after 58, then repeat: 582 / 728

On to step 3:
728 can be fit into 582 0 times, resulting in a remainder of 582.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 582 and we're left with 582.
Grab the next digit (4) from the dividend, add it to 582, then carry on: 5824 / 728

On to step 4:
728 can be fit into 5824 8 times, resulting in a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 5824 away from 5824, we end up with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 728

Moving on to step 5:
728 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 80.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 728

Advancing to step 6:
15 divided by 728 is 0 with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 800.0
Subtracting 0 from 15 leaves us with 15.
Take the next digit (9) from the dividend and append it to 15, then repeat: 159 / 728

Moving on to step 7:
159 divided by 728 is 0 with a remainder of 159.
Record the quotient 0 as the next digit in the result. 
Result so far: 8000.0
The remainder is 159 after subtracting 0 from 159.
Include the next digit (6) from the dividend after 159, then repeat: 1596 / 728

Advancing to step 8:
728 can be fit into 1596 2 times, resulting in a remainder of 140.
The next digit of our result is 2. 
Result so far: 80002.0
The remainder is 140 after subtracting 1456 from 1596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 9:
728 goes into 1400 1 times with a remainder of 672.
Use 1 as the next digit of our solution. 
Result so far: 80002.1
If we subtract 728 from 1400, we get 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Step 10:
The number 728 fits into 6720 9 times, leaving a remainder of 168.
The next digit of our result is 9. 
Result so far: 80002.19
Subtracting 6552 from 6720 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Advancing to step 11:
If we divide 1680 by 728, we get 2 and a remainder of 224.
Put 2 as the next digit of the answer. 
Result so far: 80002.192
Subtracting 1456 from 1680 leaves us with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Advancing to step 12:
If we divide 2240 by 728, we get 3 and a remainder of 56.
The number 3 becomes the next digit in our result. 
Result so far: 80002.1923
If we subtract 2184 from 2240, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 13:
When dividing 560 by 728, we get 0 with a remainder of 560.
Use 0 as the next digit of our solution. 
Result so far: 80002.1923
If we take 0 away from 560, we end up with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Going ahead to step 14:
When dividing 5600 by 728, we get 7 with a remainder of 504.
Use 7 as the next digit of our solution. 
Result so far: 80002.192307
If we take 5096 away from 5600, we end up with 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

On to step 15:
The number 728 fits into 5040 6 times, leaving a remainder of 672.
The next digit of our result is 6. 
Result so far: 80002.1923076
If we take 4368 away from 5040, we end up with 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Let's proceed to step 16:
If we divide 6720 by 728, we get 9 and a remainder of 168.
Write down 9 as next digit of the result. 
Result so far: 80002.19230769
If we take 6552 away from 6720, we end up with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

The final result is 80002.19230769 with a remainder of 1.68e-07.
