We're dividing 13773709 by 819 
The aim is to understand the frequency of 819 in 13773709.

Step 1:
If we divide 1 by 819, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 819

On to step 2:
13 divided by 819 is 0 with a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Include the next digit (7) from the dividend after 13, then repeat: 137 / 819

Let's proceed to step 3:
819 goes into 137 0 times with a remainder of 137.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 137 leaves us with 137.
Fetch the next digit (7) from the dividend, attach it to 137 and continue: 1377 / 819

Advancing to step 4:
The number 819 fits into 1377 1 times, leaving a remainder of 558.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 558 after subtracting 819 from 1377.
Take the next digit (3) from the dividend and append it to 558, then repeat: 5583 / 819

Moving on to step 5:
5583 divided by 819 is 6 with a remainder of 669.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtracting 4914 from 5583 leaves us with 669.
Include the next digit (7) from the dividend after 669, then repeat: 6697 / 819

Let's proceed to step 6:
819 goes into 6697 8 times with a remainder of 145.
Use 8 as the next digit of our solution. 
Result so far: 168.0
The remainder is 145 after subtracting 6552 from 6697.
Grab the next digit (0) from the dividend, add it to 145, then carry on: 1450 / 819

Let's proceed to step 7:
If we divide 1450 by 819, we get 1 and a remainder of 631.
The number 1 becomes the next digit in our result. 
Result so far: 1681.0
Subtracting 819 from 1450 leaves us with 631.
Fetch the next digit (9) from the dividend, attach it to 631 and continue: 6319 / 819

On to step 8:
If we divide 6319 by 819, we get 7 and a remainder of 586.
Use 7 as the next digit of our solution. 
Result so far: 16817.0
Subtracting 5733 from 6319 leaves us with 586.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5860, and continue the process.

On to step 9:
819 can be fit into 5860 7 times, resulting in a remainder of 127.
Use 7 as the next digit of our solution. 
Result so far: 16817.7
If we subtract 5733 from 5860, we get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Going ahead to step 10:
When dividing 1270 by 819, we get 1 with a remainder of 451.
Put 1 as the next digit of the answer. 
Result so far: 16817.71
Deduct 819 from 1270 and we're left with 451.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

Going ahead to step 11:
4510 divided by 819 is 5 with a remainder of 415.
Write down 5 as next digit of the result. 
Result so far: 16817.715
If we subtract 4095 from 4510, we get 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Step 12:
819 goes into 4150 5 times with a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 16817.7155
If we take 4095 away from 4150, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

In conclusion, the division gives 16817.7155 with a balance of 0.00055.
