Let's divide 43049810 by 819
The aim is to understand the frequency of 819 in 43049810.

Advancing to step 1:
If we divide 4 by 819, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 819

Moving on to step 2:
The number 819 fits into 43 0 times, leaving a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Append the next digit (0) from the dividend to 43 and continue with: 430 / 819

On to step 3:
819 can be fit into 430 0 times, resulting in a remainder of 430.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 430 after subtracting 0 from 430.
Grab the next digit (4) from the dividend, add it to 430, then carry on: 4304 / 819

Going ahead to step 4:
When dividing 4304 by 819, we get 5 with a remainder of 209.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 4095 from 4304 and we're left with 209.
Include the next digit (9) from the dividend after 209, then repeat: 2099 / 819

On to step 5:
2099 divided by 819 is 2 with a remainder of 461.
Write down 2 as next digit of the result. 
Result so far: 52.0
If we take 1638 away from 2099, we end up with 461.
Append the next digit (8) from the dividend to 461 and continue with: 4618 / 819

Advancing to step 6:
The number 819 fits into 4618 5 times, leaving a remainder of 523.
Put 5 as the next digit of the answer. 
Result so far: 525.0
The remainder is 523 after subtracting 4095 from 4618.
Grab the next digit (1) from the dividend, add it to 523, then carry on: 5231 / 819

Let's proceed to step 7:
The number 819 fits into 5231 6 times, leaving a remainder of 317.
Put 6 as the next digit of the answer. 
Result so far: 5256.0
Deduct 4914 from 5231 and we're left with 317.
Grab the next digit (0) from the dividend, add it to 317, then carry on: 3170 / 819

On to step 8:
The number 819 fits into 3170 3 times, leaving a remainder of 713.
Write down 3 as next digit of the result. 
Result so far: 52563.0
If we take 2457 away from 3170, we end up with 713.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7130, and continue the process.

Let's proceed to step 9:
7130 divided by 819 is 8 with a remainder of 578.
The next digit of our result is 8. 
Result so far: 52563.8
If we subtract 6552 from 7130, we get 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

Advancing to step 10:
The number 819 fits into 5780 7 times, leaving a remainder of 47.
Use 7 as the next digit of our solution. 
Result so far: 52563.87
Deduct 5733 from 5780 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 11:
819 can be fit into 470 0 times, resulting in a remainder of 470.
The next digit of our result is 0. 
Result so far: 52563.87
If we take 0 away from 470, we end up with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

On to step 12:
The number 819 fits into 4700 5 times, leaving a remainder of 605.
The number 5 becomes the next digit in our result. 
Result so far: 52563.8705
Subtracting 4095 from 4700 leaves us with 605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

On to step 13:
The number 819 fits into 6050 7 times, leaving a remainder of 317.
The number 7 becomes the next digit in our result. 
Result so far: 52563.87057
The remainder is 317 after subtracting 5733 from 6050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

On to step 14:
819 can be fit into 3170 3 times, resulting in a remainder of 713.
Put 3 as the next digit of the answer. 
Result so far: 52563.870573
The remainder is 713 after subtracting 2457 from 3170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7130, and continue the process.

Advancing to step 15:
The number 819 fits into 7130 8 times, leaving a remainder of 578.
Write down 8 as next digit of the result. 
Result so far: 52563.8705738
Subtracting 6552 from 7130 leaves us with 578.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5780, and continue the process.

Let's proceed to step 16:
When dividing 5780 by 819, we get 7 with a remainder of 47.
Use 7 as the next digit of our solution. 
Result so far: 52563.87057387
Subtracting 5733 from 5780 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

After the division, we end up with 52563.87057387 and a remainder of 4.7e-08.
