We look at the division of 65645306 by 493 
The aim is to understand the frequency of 493 in 65645306.

Going ahead to step 1:
When dividing 6 by 493, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 493

On to step 2:
493 goes into 65 0 times with a remainder of 65.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 65, we end up with 65.
Take the next digit (6) from the dividend and append it to 65, then repeat: 656 / 493

Step 3:
The number 493 fits into 656 1 times, leaving a remainder of 163.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 493 away from 656, we end up with 163.
Include the next digit (4) from the dividend after 163, then repeat: 1634 / 493

Moving on to step 4:
1634 divided by 493 is 3 with a remainder of 155.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Deduct 1479 from 1634 and we're left with 155.
Bring next digit (5) of the dividend behind the 155 and repeat the process: 1555 / 493

Step 5:
1555 divided by 493 is 3 with a remainder of 76.
Record the quotient 3 as the next digit in the result. 
Result so far: 133.0
If we subtract 1479 from 1555, we get 76.
Fetch the next digit (3) from the dividend, attach it to 76 and continue: 763 / 493

Going ahead to step 6:
The number 493 fits into 763 1 times, leaving a remainder of 270.
Use 1 as the next digit of our solution. 
Result so far: 1331.0
Subtracting 493 from 763 leaves us with 270.
Take the next digit (0) from the dividend and append it to 270, then repeat: 2700 / 493

Advancing to step 7:
If we divide 2700 by 493, we get 5 and a remainder of 235.
Record the quotient 5 as the next digit in the result. 
Result so far: 13315.0
If we take 2465 away from 2700, we end up with 235.
Bring next digit (6) of the dividend behind the 235 and repeat the process: 2356 / 493

Let's proceed to step 8:
The number 493 fits into 2356 4 times, leaving a remainder of 384.
The next digit of our result is 4. 
Result so far: 133154.0
The remainder is 384 after subtracting 1972 from 2356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Moving on to step 9:
If we divide 3840 by 493, we get 7 and a remainder of 389.
The next digit of our result is 7. 
Result so far: 133154.7
The remainder is 389 after subtracting 3451 from 3840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

Let's proceed to step 10:
493 can be fit into 3890 7 times, resulting in a remainder of 439.
Record the quotient 7 as the next digit in the result. 
Result so far: 133154.77
Subtracting 3451 from 3890 leaves us with 439.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4390, and continue the process.

Our division results in 133154.77 with a remaining 0.439.
