Let's divide 31343771 by 813
The aim is to understand the frequency of 813 in 31343771.

Moving on to step 1:
If we divide 3 by 813, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 813

Let's proceed to step 2:
If we divide 31 by 813, we get 0 and a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Append the next digit (3) from the dividend to 31 and continue with: 313 / 813

Advancing to step 3:
813 can be fit into 313 0 times, resulting in a remainder of 313.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 313 and we're left with 313.
Fetch the next digit (4) from the dividend, attach it to 313 and continue: 3134 / 813

On to step 4:
If we divide 3134 by 813, we get 3 and a remainder of 695.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 2439 from 3134 to get 695.
Take the next digit (3) from the dividend and append it to 695, then repeat: 6953 / 813

Let's proceed to step 5:
The number 813 fits into 6953 8 times, leaving a remainder of 449.
Use 8 as the next digit of our solution. 
Result so far: 38.0
Subtracting 6504 from 6953 leaves us with 449.
Fetch the next digit (7) from the dividend, attach it to 449 and continue: 4497 / 813

Going ahead to step 6:
813 can be fit into 4497 5 times, resulting in a remainder of 432.
Use 5 as the next digit of our solution. 
Result so far: 385.0
If we take 4065 away from 4497, we end up with 432.
Include the next digit (7) from the dividend after 432, then repeat: 4327 / 813

Step 7:
813 goes into 4327 5 times with a remainder of 262.
Put 5 as the next digit of the answer. 
Result so far: 3855.0
Deduct 4065 from 4327 and we're left with 262.
Bring next digit (1) of the dividend behind the 262 and repeat the process: 2621 / 813

Let's proceed to step 8:
2621 divided by 813 is 3 with a remainder of 182.
Record the quotient 3 as the next digit in the result. 
Result so far: 38553.0
Subtract 2439 from 2621 to get 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Advancing to step 9:
If we divide 1820 by 813, we get 2 and a remainder of 194.
Record the quotient 2 as the next digit in the result. 
Result so far: 38553.2
If we take 1626 away from 1820, we end up with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Going ahead to step 10:
If we divide 1940 by 813, we get 2 and a remainder of 314.
The next digit of our result is 2. 
Result so far: 38553.22
Subtract 1626 from 1940 to get 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

In conclusion, the division gives 38553.22 with a balance of 0.314.
