We divide 19647999 by 493
The aim is to understand the frequency of 493 in 19647999.

Advancing to step 1:
If we divide 1 by 493, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 493

On to step 2:
When dividing 19 by 493, we get 0 with a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Bring next digit (6) of the dividend behind the 19 and repeat the process: 196 / 493

Step 3:
196 divided by 493 is 0 with a remainder of 196.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 196 to get 196.
Append the next digit (4) from the dividend to 196 and continue with: 1964 / 493

Going ahead to step 4:
The number 493 fits into 1964 3 times, leaving a remainder of 485.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 1479 from 1964, we get 485.
Bring next digit (7) of the dividend behind the 485 and repeat the process: 4857 / 493

Let's proceed to step 5:
493 goes into 4857 9 times with a remainder of 420.
The next digit of our result is 9. 
Result so far: 39.0
The remainder is 420 after subtracting 4437 from 4857.
Append the next digit (9) from the dividend to 420 and continue with: 4209 / 493

Advancing to step 6:
When dividing 4209 by 493, we get 8 with a remainder of 265.
The next digit of our result is 8. 
Result so far: 398.0
The remainder is 265 after subtracting 3944 from 4209.
Include the next digit (9) from the dividend after 265, then repeat: 2659 / 493

On to step 7:
The number 493 fits into 2659 5 times, leaving a remainder of 194.
Use 5 as the next digit of our solution. 
Result so far: 3985.0
Subtract 2465 from 2659 to get 194.
Take the next digit (9) from the dividend and append it to 194, then repeat: 1949 / 493

Let's proceed to step 8:
493 can be fit into 1949 3 times, resulting in a remainder of 470.
Put 3 as the next digit of the answer. 
Result so far: 39853.0
Subtracting 1479 from 1949 leaves us with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Advancing to step 9:
When dividing 4700 by 493, we get 9 with a remainder of 263.
The number 9 becomes the next digit in our result. 
Result so far: 39853.9
Subtract 4437 from 4700 to get 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

On to step 10:
When dividing 2630 by 493, we get 5 with a remainder of 165.
Write down 5 as next digit of the result. 
Result so far: 39853.95
Deduct 2465 from 2630 and we're left with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Advancing to step 11:
493 goes into 1650 3 times with a remainder of 171.
Record the quotient 3 as the next digit in the result. 
Result so far: 39853.953
If we take 1479 away from 1650, we end up with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

On to step 12:
493 goes into 1710 3 times with a remainder of 231.
The next digit of our result is 3. 
Result so far: 39853.9533
Deduct 1479 from 1710 and we're left with 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

The final outcome is 39853.9533, with a leftover of 0.00231.
