31133009 divided by 819 
The aim is to understand the frequency of 819 in 31133009.

Moving on to step 1:
If we divide 3 by 819, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 819

Advancing to step 2:
819 goes into 31 0 times with a remainder of 31.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Bring next digit (1) of the dividend behind the 31 and repeat the process: 311 / 819

On to step 3:
When dividing 311 by 819, we get 0 with a remainder of 311.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 311, we end up with 311.
Bring next digit (3) of the dividend behind the 311 and repeat the process: 3113 / 819

Let's proceed to step 4:
If we divide 3113 by 819, we get 3 and a remainder of 656.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 2457 from 3113 and we're left with 656.
Fetch the next digit (3) from the dividend, attach it to 656 and continue: 6563 / 819

Step 5:
6563 divided by 819 is 8 with a remainder of 11.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
If we take 6552 away from 6563, we end up with 11.
Take the next digit (0) from the dividend and append it to 11, then repeat: 110 / 819

Let's proceed to step 6:
819 can be fit into 110 0 times, resulting in a remainder of 110.
Write down 0 as next digit of the result. 
Result so far: 380.0
If we take 0 away from 110, we end up with 110.
Take the next digit (0) from the dividend and append it to 110, then repeat: 1100 / 819

On to step 7:
819 can be fit into 1100 1 times, resulting in a remainder of 281.
Record the quotient 1 as the next digit in the result. 
Result so far: 3801.0
If we take 819 away from 1100, we end up with 281.
Fetch the next digit (9) from the dividend, attach it to 281 and continue: 2819 / 819

Advancing to step 8:
The number 819 fits into 2819 3 times, leaving a remainder of 362.
Record the quotient 3 as the next digit in the result. 
Result so far: 38013.0
If we take 2457 away from 2819, we end up with 362.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Let's proceed to step 9:
If we divide 3620 by 819, we get 4 and a remainder of 344.
The next digit of our result is 4. 
Result so far: 38013.4
If we subtract 3276 from 3620, we get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Let's proceed to step 10:
If we divide 3440 by 819, we get 4 and a remainder of 164.
The number 4 becomes the next digit in our result. 
Result so far: 38013.44
The remainder is 164 after subtracting 3276 from 3440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

The final result is 38013.44 with a remainder of 0.164.
