We divide 30949715 by 813
The aim is to understand the frequency of 813 in 30949715.

Let's proceed to step 1:
When dividing 3 by 813, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 813

Going ahead to step 2:
30 divided by 813 is 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Append the next digit (9) from the dividend to 30 and continue with: 309 / 813

Going ahead to step 3:
When dividing 309 by 813, we get 0 with a remainder of 309.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 309, we end up with 309.
Take the next digit (4) from the dividend and append it to 309, then repeat: 3094 / 813

Step 4:
When dividing 3094 by 813, we get 3 with a remainder of 655.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 2439 from 3094 leaves us with 655.
Take the next digit (9) from the dividend and append it to 655, then repeat: 6559 / 813

On to step 5:
If we divide 6559 by 813, we get 8 and a remainder of 55.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
If we take 6504 away from 6559, we end up with 55.
Include the next digit (7) from the dividend after 55, then repeat: 557 / 813

Let's proceed to step 6:
The number 813 fits into 557 0 times, leaving a remainder of 557.
The number 0 becomes the next digit in our result. 
Result so far: 380.0
The remainder is 557 after subtracting 0 from 557.
Grab the next digit (1) from the dividend, add it to 557, then carry on: 5571 / 813

On to step 7:
813 goes into 5571 6 times with a remainder of 693.
Use 6 as the next digit of our solution. 
Result so far: 3806.0
Deduct 4878 from 5571 and we're left with 693.
Grab the next digit (5) from the dividend, add it to 693, then carry on: 6935 / 813

Going ahead to step 8:
6935 divided by 813 is 8 with a remainder of 431.
The next digit of our result is 8. 
Result so far: 38068.0
Subtracting 6504 from 6935 leaves us with 431.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4310, and continue the process.

On to step 9:
When dividing 4310 by 813, we get 5 with a remainder of 245.
The next digit of our result is 5. 
Result so far: 38068.5
If we subtract 4065 from 4310, we get 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

On to step 10:
2450 divided by 813 is 3 with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 38068.53
If we subtract 2439 from 2450, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 11:
110 divided by 813 is 0 with a remainder of 110.
Put 0 as the next digit of the answer. 
Result so far: 38068.53
If we subtract 0 from 110, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 12:
813 can be fit into 1100 1 times, resulting in a remainder of 287.
The number 1 becomes the next digit in our result. 
Result so far: 38068.5301
If we subtract 813 from 1100, we get 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

On to step 13:
2870 divided by 813 is 3 with a remainder of 431.
The next digit of our result is 3. 
Result so far: 38068.53013
If we subtract 2439 from 2870, we get 431.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4310, and continue the process.

Let's proceed to step 14:
If we divide 4310 by 813, we get 5 and a remainder of 245.
Record the quotient 5 as the next digit in the result. 
Result so far: 38068.530135
Subtracting 4065 from 4310 leaves us with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Going ahead to step 15:
If we divide 2450 by 813, we get 3 and a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 38068.5301353
Subtract 2439 from 2450 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 16:
110 divided by 813 is 0 with a remainder of 110.
Use 0 as the next digit of our solution. 
Result so far: 38068.5301353
If we take 0 away from 110, we end up with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

The final outcome is 38068.5301353, with a leftover of 1.1e-07.
