We look at the division of 24198891 by 819 
The aim is to understand the frequency of 819 in 24198891.

Let's proceed to step 1:
819 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 819

Advancing to step 2:
819 goes into 24 0 times with a remainder of 24.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 24 and we're left with 24.
Include the next digit (1) from the dividend after 24, then repeat: 241 / 819

Advancing to step 3:
819 goes into 241 0 times with a remainder of 241.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 241 leaves us with 241.
Grab the next digit (9) from the dividend, add it to 241, then carry on: 2419 / 819

Advancing to step 4:
If we divide 2419 by 819, we get 2 and a remainder of 781.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 1638 from 2419 to get 781.
Append the next digit (8) from the dividend to 781 and continue with: 7818 / 819

Going ahead to step 5:
If we divide 7818 by 819, we get 9 and a remainder of 447.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
Subtracting 7371 from 7818 leaves us with 447.
Include the next digit (8) from the dividend after 447, then repeat: 4478 / 819

Step 6:
819 can be fit into 4478 5 times, resulting in a remainder of 383.
Write down 5 as next digit of the result. 
Result so far: 295.0
Subtracting 4095 from 4478 leaves us with 383.
Take the next digit (9) from the dividend and append it to 383, then repeat: 3839 / 819

Going ahead to step 7:
If we divide 3839 by 819, we get 4 and a remainder of 563.
Use 4 as the next digit of our solution. 
Result so far: 2954.0
Deduct 3276 from 3839 and we're left with 563.
Append the next digit (1) from the dividend to 563 and continue with: 5631 / 819

Moving on to step 8:
The number 819 fits into 5631 6 times, leaving a remainder of 717.
Write down 6 as next digit of the result. 
Result so far: 29546.0
If we subtract 4914 from 5631, we get 717.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7170, and continue the process.

Going ahead to step 9:
7170 divided by 819 is 8 with a remainder of 618.
Put 8 as the next digit of the answer. 
Result so far: 29546.8
If we take 6552 away from 7170, we end up with 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

On to step 10:
819 goes into 6180 7 times with a remainder of 447.
Write down 7 as next digit of the result. 
Result so far: 29546.87
If we take 5733 away from 6180, we end up with 447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

On to step 11:
4470 divided by 819 is 5 with a remainder of 375.
Use 5 as the next digit of our solution. 
Result so far: 29546.875
Subtract 4095 from 4470 to get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Advancing to step 12:
819 can be fit into 3750 4 times, resulting in a remainder of 474.
Write down 4 as next digit of the result. 
Result so far: 29546.8754
The remainder is 474 after subtracting 3276 from 3750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Let's proceed to step 13:
819 can be fit into 4740 5 times, resulting in a remainder of 645.
The number 5 becomes the next digit in our result. 
Result so far: 29546.87545
Subtracting 4095 from 4740 leaves us with 645.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6450, and continue the process.

On to step 14:
819 can be fit into 6450 7 times, resulting in a remainder of 717.
The number 7 becomes the next digit in our result. 
Result so far: 29546.875457
If we subtract 5733 from 6450, we get 717.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7170, and continue the process.

Let's proceed to step 15:
The number 819 fits into 7170 8 times, leaving a remainder of 618.
Record the quotient 8 as the next digit in the result. 
Result so far: 29546.8754578
Deduct 6552 from 7170 and we're left with 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

Going ahead to step 16:
819 can be fit into 6180 7 times, resulting in a remainder of 447.
The number 7 becomes the next digit in our result. 
Result so far: 29546.87545787
If we take 5733 away from 6180, we end up with 447.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4470, and continue the process.

After the division, we end up with 29546.87545787 and a remainder of 4.47e-07.
