Let's divide 74921266 by 728
The aim is to understand the frequency of 728 in 74921266.

Advancing to step 1:
The number 728 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 728

Moving on to step 2:
74 divided by 728 is 0 with a remainder of 74.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 74, we get 74.
Take the next digit (9) from the dividend and append it to 74, then repeat: 749 / 728

Going ahead to step 3:
The number 728 fits into 749 1 times, leaving a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 728 from 749, we get 21.
Bring next digit (2) of the dividend behind the 21 and repeat the process: 212 / 728

Going ahead to step 4:
728 can be fit into 212 0 times, resulting in a remainder of 212.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 212 to get 212.
Include the next digit (1) from the dividend after 212, then repeat: 2121 / 728

Let's proceed to step 5:
728 goes into 2121 2 times with a remainder of 665.
Put 2 as the next digit of the answer. 
Result so far: 102.0
Deduct 1456 from 2121 and we're left with 665.
Take the next digit (2) from the dividend and append it to 665, then repeat: 6652 / 728

Step 6:
728 goes into 6652 9 times with a remainder of 100.
Record the quotient 9 as the next digit in the result. 
Result so far: 1029.0
Subtracting 6552 from 6652 leaves us with 100.
Append the next digit (6) from the dividend to 100 and continue with: 1006 / 728

Moving on to step 7:
When dividing 1006 by 728, we get 1 with a remainder of 278.
Put 1 as the next digit of the answer. 
Result so far: 10291.0
The remainder is 278 after subtracting 728 from 1006.
Bring next digit (6) of the dividend behind the 278 and repeat the process: 2786 / 728

Let's proceed to step 8:
728 goes into 2786 3 times with a remainder of 602.
The next digit of our result is 3. 
Result so far: 102913.0
If we subtract 2184 from 2786, we get 602.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6020, and continue the process.

Let's proceed to step 9:
728 goes into 6020 8 times with a remainder of 196.
Put 8 as the next digit of the answer. 
Result so far: 102913.8
Deduct 5824 from 6020 and we're left with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Moving on to step 10:
If we divide 1960 by 728, we get 2 and a remainder of 504.
Record the quotient 2 as the next digit in the result. 
Result so far: 102913.82
If we take 1456 away from 1960, 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.

Advancing to step 11:
When dividing 5040 by 728, we get 6 with a remainder of 672.
Use 6 as the next digit of our solution. 
Result so far: 102913.826
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.

Moving on to step 12:
The number 728 fits into 6720 9 times, leaving a remainder of 168.
Write down 9 as next digit of the result. 
Result so far: 102913.8269
If we subtract 6552 from 6720, we get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Step 13:
1680 divided by 728 is 2 with a remainder of 224.
The number 2 becomes the next digit in our result. 
Result so far: 102913.82692
Deduct 1456 from 1680 and we're left 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.

Step 14:
The number 728 fits into 2240 3 times, leaving a remainder of 56.
Record the quotient 3 as the next digit in the result. 
Result so far: 102913.826923
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.

On to step 15:
When dividing 560 by 728, we get 0 with a remainder of 560.
Write down 0 as next digit of the result. 
Result so far: 102913.826923
The remainder is 560 after subtracting 0 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Let's proceed to step 16:
When dividing 5600 by 728, we get 7 with a remainder of 504.
The next digit of our result is 7. 
Result so far: 102913.82692307
Subtract 5096 from 5600 to get 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

The quotient of the division is 102913.82692307, and the remainder is 5.04e-07.
