We divide 21808397 by 727
The aim is to understand the frequency of 727 in 21808397.

Let's proceed to step 1:
727 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 727

Let's proceed to step 2:
The number 727 fits into 21 0 times, leaving a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Append the next digit (8) from the dividend to 21 and continue with: 218 / 727

On to step 3:
The number 727 fits into 218 0 times, leaving a remainder of 218.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 218 leaves us with 218.
Include the next digit (0) from the dividend after 218, then repeat: 2180 / 727

Let's proceed to step 4:
The number 727 fits into 2180 2 times, leaving a remainder of 726.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 1454 from 2180 leaves us with 726.
Bring next digit (8) of the dividend behind the 726 and repeat the process: 7268 / 727

On to step 5:
727 can be fit into 7268 9 times, resulting in a remainder of 725.
Put 9 as the next digit of the answer. 
Result so far: 29.0
If we subtract 6543 from 7268, we get 725.
Include the next digit (3) from the dividend after 725, then repeat: 7253 / 727

Moving on to step 6:
7253 divided by 727 is 9 with a remainder of 710.
Use 9 as the next digit of our solution. 
Result so far: 299.0
If we subtract 6543 from 7253, we get 710.
Include the next digit (9) from the dividend after 710, then repeat: 7109 / 727

On to step 7:
727 can be fit into 7109 9 times, resulting in a remainder of 566.
Write down 9 as next digit of the result. 
Result so far: 2999.0
The remainder is 566 after subtracting 6543 from 7109.
Take the next digit (7) from the dividend and append it to 566, then repeat: 5667 / 727

On to step 8:
727 goes into 5667 7 times with a remainder of 578.
Put 7 as the next digit of the answer. 
Result so far: 29997.0
Subtract 5089 from 5667 to get 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

On to step 9:
727 goes into 5780 7 times with a remainder of 691.
Use 7 as the next digit of our solution. 
Result so far: 29997.7
If we take 5089 away from 5780, we end up with 691.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6910, and continue the process.

Let's proceed to step 10:
727 goes into 6910 9 times with a remainder of 367.
Record the quotient 9 as the next digit in the result. 
Result so far: 29997.79
If we take 6543 away from 6910, we end up with 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Step 11:
The number 727 fits into 3670 5 times, leaving a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 29997.795
If we take 3635 away from 3670, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 12:
727 goes into 350 0 times with a remainder of 350.
Write down 0 as next digit of the result. 
Result so far: 29997.795
If we subtract 0 from 350, we get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Advancing to step 13:
If we divide 3500 by 727, we get 4 and a remainder of 592.
Put 4 as the next digit of the answer. 
Result so far: 29997.79504
Subtracting 2908 from 3500 leaves us with 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

On to step 14:
5920 divided by 727 is 8 with a remainder of 104.
Write down 8 as next digit of the result. 
Result so far: 29997.795048
If we subtract 5816 from 5920, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Let's proceed to step 15:
The number 727 fits into 1040 1 times, leaving a remainder of 313.
Put 1 as the next digit of the answer. 
Result so far: 29997.7950481
Subtracting 727 from 1040 leaves us with 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Let's proceed to step 16:
727 can be fit into 3130 4 times, resulting in a remainder of 222.
Write down 4 as next digit of the result. 
Result so far: 29997.79504814
If we take 2908 away from 3130, we end up with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

The quotient of the division is 29997.79504814, and the remainder is 2.22e-07.
