We're dividing 23590429 by 728 
The aim is to understand the frequency of 728 in 23590429.

Moving on to step 1:
728 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 728

Step 2:
23 divided by 728 is 0 with a remainder of 23.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 23 and we're left with 23.
Grab the next digit (5) from the dividend, add it to 23, then carry on: 235 / 728

On to step 3:
If we divide 235 by 728, we get 0 and a remainder of 235.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 235, we get 235.
Append the next digit (9) from the dividend to 235 and continue with: 2359 / 728

On to step 4:
2359 divided by 728 is 3 with a remainder of 175.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 2184 from 2359 leaves us with 175.
Include the next digit (0) from the dividend after 175, then repeat: 1750 / 728

On to step 5:
728 can be fit into 1750 2 times, resulting in a remainder of 294.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
If we take 1456 away from 1750, we end up with 294.
Include the next digit (4) from the dividend after 294, then repeat: 2944 / 728

Let's proceed to step 6:
728 can be fit into 2944 4 times, resulting in a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 324.0
Deduct 2912 from 2944 and we're left with 32.
Grab the next digit (2) from the dividend, add it to 32, then carry on: 322 / 728

Moving on to step 7:
If we divide 322 by 728, we get 0 and a remainder of 322.
Write down 0 as next digit of the result. 
Result so far: 3240.0
The remainder is 322 after subtracting 0 from 322.
Append the next digit (9) from the dividend to 322 and continue with: 3229 / 728

Going ahead to step 8:
When dividing 3229 by 728, we get 4 with a remainder of 317.
Write down 4 as next digit of the result. 
Result so far: 32404.0
If we subtract 2912 from 3229, we get 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

Advancing to step 9:
The number 728 fits into 3170 4 times, leaving a remainder of 258.
Use 4 as the next digit of our solution. 
Result so far: 32404.4
If we subtract 2912 from 3170, we get 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Advancing to step 10:
728 can be fit into 2580 3 times, resulting in a remainder of 396.
Write down 3 as next digit of the result. 
Result so far: 32404.43
If we subtract 2184 from 2580, we get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Step 11:
728 goes into 3960 5 times with a remainder of 320.
Write down 5 as next digit of the result. 
Result so far: 32404.435
The remainder is 320 after subtracting 3640 from 3960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 12:
The number 728 fits into 3200 4 times, leaving a remainder of 288.
Record the quotient 4 as the next digit in the result. 
Result so far: 32404.4354
If we subtract 2912 from 3200, we get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Moving on to step 13:
If we divide 2880 by 728, we get 3 and a remainder of 696.
Record the quotient 3 as the next digit in the result. 
Result so far: 32404.43543
If we subtract 2184 from 2880, we get 696.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

Going ahead to step 14:
728 goes into 6960 9 times with a remainder of 408.
Record the quotient 9 as the next digit in the result. 
Result so far: 32404.435439
If we take 6552 away from 6960, we end up with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Advancing to step 15:
When dividing 4080 by 728, we get 5 with a remainder of 440.
Write down 5 as next digit of the result. 
Result so far: 32404.4354395
If we subtract 3640 from 4080, we get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Advancing to step 16:
728 can be fit into 4400 6 times, resulting in a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 32404.43543956
Subtracting 4368 from 4400 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

In conclusion, the division gives 32404.43543956 with a balance of 3.2e-08.
