We divide 30827731 by 728
The aim is to understand the frequency of 728 in 30827731.

Step 1:
When dividing 3 by 728, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 728

Step 2:
If we divide 30 by 728, we get 0 and a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Bring next digit (8) of the dividend behind the 30 and repeat the process: 308 / 728

Advancing to step 3:
308 divided by 728 is 0 with a remainder of 308.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 308 and we're left with 308.
Append the next digit (2) from the dividend to 308 and continue with: 3082 / 728

Let's proceed to step 4:
When dividing 3082 by 728, we get 4 with a remainder of 170.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we take 2912 away from 3082, we end up with 170.
Append the next digit (7) from the dividend to 170 and continue with: 1707 / 728

Going ahead to step 5:
728 goes into 1707 2 times with a remainder of 251.
Put 2 as the next digit of the answer. 
Result so far: 42.0
If we subtract 1456 from 1707, we get 251.
Append the next digit (7) from the dividend to 251 and continue with: 2517 / 728

Step 6:
If we divide 2517 by 728, we get 3 and a remainder of 333.
The number 3 becomes the next digit in our result. 
Result so far: 423.0
Subtracting 2184 from 2517 leaves us with 333.
Bring next digit (3) of the dividend behind the 333 and repeat the process: 3333 / 728

Advancing to step 7:
When dividing 3333 by 728, we get 4 with a remainder of 421.
Record the quotient 4 as the next digit in the result. 
Result so far: 4234.0
If we subtract 2912 from 3333, we get 421.
Bring next digit (1) of the dividend behind the 421 and repeat the process: 4211 / 728

Going ahead to step 8:
4211 divided by 728 is 5 with a remainder of 571.
Write down 5 as next digit of the result. 
Result so far: 42345.0
Subtracting 3640 from 4211 leaves us with 571.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5710, and continue the process.

Advancing to step 9:
The number 728 fits into 5710 7 times, leaving a remainder of 614.
Use 7 as the next digit of our solution. 
Result so far: 42345.7
Deduct 5096 from 5710 and we're left with 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

Advancing to step 10:
If we divide 6140 by 728, we get 8 and a remainder of 316.
The number 8 becomes the next digit in our result. 
Result so far: 42345.78
Subtract 5824 from 6140 to get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Advancing to step 11:
728 can be fit into 3160 4 times, resulting in a remainder of 248.
The number 4 becomes the next digit in our result. 
Result so far: 42345.784
Deduct 2912 from 3160 and we're left with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Step 12:
728 goes into 2480 3 times with a remainder of 296.
Write down 3 as next digit of the result. 
Result so far: 42345.7843
If we take 2184 away from 2480, we end up with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Let's proceed to step 13:
The number 728 fits into 2960 4 times, leaving a remainder of 48.
The next digit of our result is 4. 
Result so far: 42345.78434
If we take 2912 away from 2960, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 14:
When dividing 480 by 728, we get 0 with a remainder of 480.
The next digit of our result is 0. 
Result so far: 42345.78434
If we take 0 away from 480, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 15:
728 goes into 4800 6 times with a remainder of 432.
Put 6 as the next digit of the answer. 
Result so far: 42345.7843406
If we take 4368 away from 4800, we end up with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

On to step 16:
4320 divided by 728 is 5 with a remainder of 680.
Write down 5 as next digit of the result. 
Result so far: 42345.78434065
The remainder is 680 after subtracting 3640 from 4320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

In conclusion, the division gives 42345.78434065 with a balance of 6.8e-07.
