We look at the division of 30309773 by 814 
The aim is to understand the frequency of 814 in 30309773.

Let's proceed to step 1:
If we divide 3 by 814, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 814

Advancing to step 2:
When dividing 30 by 814, we get 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Take the next digit (3) from the dividend and append it to 30, then repeat: 303 / 814

Step 3:
When dividing 303 by 814, we get 0 with a remainder of 303.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 303 and we're left with 303.
Include the next digit (0) from the dividend after 303, then repeat: 3030 / 814

On to step 4:
The number 814 fits into 3030 3 times, leaving a remainder of 588.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 2442 from 3030 leaves us with 588.
Take the next digit (9) from the dividend and append it to 588, then repeat: 5889 / 814

Step 5:
When dividing 5889 by 814, we get 7 with a remainder of 191.
Put 7 as the next digit of the answer. 
Result so far: 37.0
If we subtract 5698 from 5889, we get 191.
Bring next digit (7) of the dividend behind the 191 and repeat the process: 1917 / 814

Advancing to step 6:
If we divide 1917 by 814, we get 2 and a remainder of 289.
The next digit of our result is 2. 
Result so far: 372.0
Subtracting 1628 from 1917 leaves us with 289.
Bring next digit (7) of the dividend behind the 289 and repeat the process: 2897 / 814

Advancing to step 7:
814 goes into 2897 3 times with a remainder of 455.
The next digit of our result is 3. 
Result so far: 3723.0
The remainder is 455 after subtracting 2442 from 2897.
Take the next digit (3) from the dividend and append it to 455, then repeat: 4553 / 814

Advancing to step 8:
If we divide 4553 by 814, we get 5 and a remainder of 483.
Write down 5 as next digit of the result. 
Result so far: 37235.0
Deduct 4070 from 4553 and we're left with 483.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4830, and continue the process.

Going ahead to step 9:
4830 divided by 814 is 5 with a remainder of 760.
Record the quotient 5 as the next digit in the result. 
Result so far: 37235.5
If we take 4070 away from 4830, we end up with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Advancing to step 10:
The number 814 fits into 7600 9 times, leaving a remainder of 274.
Record the quotient 9 as the next digit in the result. 
Result so far: 37235.59
Subtracting 7326 from 7600 leaves us with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Step 11:
814 goes into 2740 3 times with a remainder of 298.
Write down 3 as next digit of the result. 
Result so far: 37235.593
If we subtract 2442 from 2740, we get 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Step 12:
When dividing 2980 by 814, we get 3 with a remainder of 538.
Write down 3 as next digit of the result. 
Result so far: 37235.5933
If we take 2442 away from 2980, we end up with 538.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

The quotient of the division is 37235.5933, and the remainder is 0.00538.
