We're dividing 43247230 by 815 
The aim is to understand the frequency of 815 in 43247230.

Moving on to step 1:
815 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 815

Step 2:
815 can be fit into 43 0 times, resulting in a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Append the next digit (2) from the dividend to 43 and continue with: 432 / 815

Going ahead to step 3:
432 divided by 815 is 0 with a remainder of 432.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 432 and we're left with 432.
Grab the next digit (4) from the dividend, add it to 432, then carry on: 4324 / 815

Moving on to step 4:
815 goes into 4324 5 times with a remainder of 249.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 4075 from 4324, we get 249.
Include the next digit (7) from the dividend after 249, then repeat: 2497 / 815

Step 5:
The number 815 fits into 2497 3 times, leaving a remainder of 52.
The next digit of our result is 3. 
Result so far: 53.0
If we take 2445 away from 2497, we end up with 52.
Take the next digit (2) from the dividend and append it to 52, then repeat: 522 / 815

Step 6:
When dividing 522 by 815, we get 0 with a remainder of 522.
Put 0 as the next digit of the answer. 
Result so far: 530.0
Deduct 0 from 522 and we're left with 522.
Fetch the next digit (3) from the dividend, attach it to 522 and continue: 5223 / 815

Step 7:
If we divide 5223 by 815, we get 6 and a remainder of 333.
Use 6 as the next digit of our solution. 
Result so far: 5306.0
Subtract 4890 from 5223 to get 333.
Append the next digit (0) from the dividend to 333 and continue with: 3330 / 815

Going ahead to step 8:
3330 divided by 815 is 4 with a remainder of 70.
Record the quotient 4 as the next digit in the result. 
Result so far: 53064.0
The remainder is 70 after subtracting 3260 from 3330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 9:
815 can be fit into 700 0 times, resulting in a remainder of 700.
The number 0 becomes the next digit in our result. 
Result so far: 53064.0
If we subtract 0 from 700, we get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Let's proceed to step 10:
815 can be fit into 7000 8 times, resulting in a remainder of 480.
Record the quotient 8 as the next digit in the result. 
Result so far: 53064.08
Subtract 6520 from 7000 to get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Step 11:
If we divide 4800 by 815, we get 5 and a remainder of 725.
Write down 5 as next digit of the result. 
Result so far: 53064.085
Deduct 4075 from 4800 and we're left with 725.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7250, and continue the process.

On to step 12:
The number 815 fits into 7250 8 times, leaving a remainder of 730.
The next digit of our result is 8. 
Result so far: 53064.0858
If we take 6520 away from 7250, we end up with 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Step 13:
The number 815 fits into 7300 8 times, leaving a remainder of 780.
The number 8 becomes the next digit in our result. 
Result so far: 53064.08588
The remainder is 780 after subtracting 6520 from 7300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

The quotient of the division is 53064.08588, and the remainder is 0.00078.
