We divide 16537709 by 728
The aim is to understand the frequency of 728 in 16537709.

Step 1:
When dividing 1 by 728, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 728

Going ahead to step 2:
When dividing 16 by 728, we get 0 with a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Append the next digit (5) from the dividend to 16 and continue with: 165 / 728

Going ahead to step 3:
When dividing 165 by 728, we get 0 with a remainder of 165.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 165 leaves us with 165.
Append the next digit (3) from the dividend to 165 and continue with: 1653 / 728

Moving on to step 4:
The number 728 fits into 1653 2 times, leaving a remainder of 197.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 1456 from 1653 leaves us with 197.
Grab the next digit (7) from the dividend, add it to 197, then carry on: 1977 / 728

Step 5:
If we divide 1977 by 728, we get 2 and a remainder of 521.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
If we subtract 1456 from 1977, we get 521.
Append the next digit (7) from the dividend to 521 and continue with: 5217 / 728

Going ahead to step 6:
The number 728 fits into 5217 7 times, leaving a remainder of 121.
Use 7 as the next digit of our solution. 
Result so far: 227.0
Subtracting 5096 from 5217 leaves us with 121.
Bring next digit (0) of the dividend behind the 121 and repeat the process: 1210 / 728

Moving on to step 7:
728 goes into 1210 1 times with a remainder of 482.
The number 1 becomes the next digit in our result. 
Result so far: 2271.0
If we take 728 away from 1210, we end up with 482.
Include the next digit (9) from the dividend after 482, then repeat: 4829 / 728

Step 8:
728 goes into 4829 6 times with a remainder of 461.
The next digit of our result is 6. 
Result so far: 22716.0
Subtracting 4368 from 4829 leaves us with 461.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4610, and continue the process.

Let's proceed to step 9:
4610 divided by 728 is 6 with a remainder of 242.
Record the quotient 6 as the next digit in the result. 
Result so far: 22716.6
Subtract 4368 from 4610 to get 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Step 10:
728 goes into 2420 3 times with a remainder of 236.
The number 3 becomes the next digit in our result. 
Result so far: 22716.63
If we take 2184 away from 2420, we end up with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Advancing to step 11:
When dividing 2360 by 728, we get 3 with a remainder of 176.
The number 3 becomes the next digit in our result. 
Result so far: 22716.633
Subtracting 2184 from 2360 leaves us with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

The final result is 22716.633 with a remainder of 0.0176.
