We divide 2304505 by 815
The aim is to understand the frequency of 815 in 2304505.

On to step 1:
The number 815 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 815

On to step 2:
815 goes into 23 0 times with a remainder of 23.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 23 leaves us with 23.
Bring next digit (0) of the dividend behind the 23 and repeat the process: 230 / 815

Going ahead to step 3:
If we divide 230 by 815, we get 0 and a remainder of 230.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 230 to get 230.
Take the next digit (4) from the dividend and append it to 230, then repeat: 2304 / 815

Let's proceed to step 4:
2304 divided by 815 is 2 with a remainder of 674.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 1630 from 2304 and we're left with 674.
Fetch the next digit (5) from the dividend, attach it to 674 and continue: 6745 / 815

Moving on to step 5:
If we divide 6745 by 815, we get 8 and a remainder of 225.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
The remainder is 225 after subtracting 6520 from 6745.
Include the next digit (0) from the dividend after 225, then repeat: 2250 / 815

Step 6:
2250 divided by 815 is 2 with a remainder of 620.
Put 2 as the next digit of the answer. 
Result so far: 282.0
If we take 1630 away from 2250, we end up with 620.
Grab the next digit (5) from the dividend, add it to 620, then carry on: 6205 / 815

Step 7:
6205 divided by 815 is 7 with a remainder of 500.
The number 7 becomes the next digit in our result. 
Result so far: 2827.0
If we subtract 5705 from 6205, we get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Let's proceed to step 8:
The number 815 fits into 5000 6 times, leaving a remainder of 110.
The next digit of our result is 6. 
Result so far: 2827.6
Subtracting 4890 from 5000 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 9:
1100 divided by 815 is 1 with a remainder of 285.
Record the quotient 1 as the next digit in the result. 
Result so far: 2827.61
If we subtract 815 from 1100, we get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

On to step 10:
The number 815 fits into 2850 3 times, leaving a remainder of 405.
Write down 3 as next digit of the result. 
Result so far: 2827.613
If we subtract 2445 from 2850, we get 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

On to step 11:
815 can be fit into 4050 4 times, resulting in a remainder of 790.
Record the quotient 4 as the next digit in the result. 
Result so far: 2827.6134
If we subtract 3260 from 4050, we get 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

On to step 12:
When dividing 7900 by 815, we get 9 with a remainder of 565.
Write down 9 as next digit of the result. 
Result so far: 2827.61349
Subtract 7335 from 7900 to get 565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

Going ahead to step 13:
5650 divided by 815 is 6 with a remainder of 760.
Put 6 as the next digit of the answer. 
Result so far: 2827.613496
Subtracting 4890 from 5650 leaves us with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Let's proceed to step 14:
815 goes into 7600 9 times with a remainder of 265.
Record the quotient 9 as the next digit in the result. 
Result so far: 2827.6134969
If we take 7335 away from 7600, we end up with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Advancing to step 15:
If we divide 2650 by 815, we get 3 and a remainder of 205.
The next digit of our result is 3. 
Result so far: 2827.61349693
If we take 2445 away from 2650, we end up with 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Our division results in 2827.61349693 with a remaining 2.05e-07.
