Let's divide 56027600 by 815
The aim is to understand the frequency of 815 in 56027600.

Moving on to step 1:
If we divide 5 by 815, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 815

Going ahead to step 2:
815 can be fit into 56 0 times, resulting in a remainder of 56.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 56, we get 56.
Include the next digit (0) from the dividend after 56, then repeat: 560 / 815

Going ahead to step 3:
815 can be fit into 560 0 times, resulting in a remainder of 560.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 560 after subtracting 0 from 560.
Include the next digit (2) from the dividend after 560, then repeat: 5602 / 815

On to step 4:
The number 815 fits into 5602 6 times, leaving a remainder of 712.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 4890 from 5602 and we're left with 712.
Include the next digit (7) from the dividend after 712, then repeat: 7127 / 815

Step 5:
The number 815 fits into 7127 8 times, leaving a remainder of 607.
The next digit of our result is 8. 
Result so far: 68.0
Subtract 6520 from 7127 to get 607.
Bring next digit (6) of the dividend behind the 607 and repeat the process: 6076 / 815

Going ahead to step 6:
815 goes into 6076 7 times with a remainder of 371.
The next digit of our result is 7. 
Result so far: 687.0
If we take 5705 away from 6076, we end up with 371.
Append the next digit (0) from the dividend to 371 and continue with: 3710 / 815

Step 7:
815 can be fit into 3710 4 times, resulting in a remainder of 450.
Record the quotient 4 as the next digit in the result. 
Result so far: 6874.0
The remainder is 450 after subtracting 3260 from 3710.
Take the next digit (0) from the dividend and append it to 450, then repeat: 4500 / 815

Let's proceed to step 8:
When dividing 4500 by 815, we get 5 with a remainder of 425.
Use 5 as the next digit of our solution. 
Result so far: 68745.0
The remainder is 425 after subtracting 4075 from 4500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Moving on to step 9:
When dividing 4250 by 815, we get 5 with a remainder of 175.
Write down 5 as next digit of the result. 
Result so far: 68745.5
If we subtract 4075 from 4250, we get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

On to step 10:
815 goes into 1750 2 times with a remainder of 120.
Put 2 as the next digit of the answer. 
Result so far: 68745.52
If we take 1630 away from 1750, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 11:
If we divide 1200 by 815, we get 1 and a remainder of 385.
The number 1 becomes the next digit in our result. 
Result so far: 68745.521
If we subtract 815 from 1200, we get 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Moving on to step 12:
815 can be fit into 3850 4 times, resulting in a remainder of 590.
The number 4 becomes the next digit in our result. 
Result so far: 68745.5214
Subtracting 3260 from 3850 leaves us with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

On to step 13:
When dividing 5900 by 815, we get 7 with a remainder of 195.
The next digit of our result is 7. 
Result so far: 68745.52147
The remainder is 195 after subtracting 5705 from 5900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

On to step 14:
The number 815 fits into 1950 2 times, leaving a remainder of 320.
The next digit of our result is 2. 
Result so far: 68745.521472
Subtracting 1630 from 1950 leaves us with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 15:
When dividing 3200 by 815, we get 3 with a remainder of 755.
Write down 3 as next digit of the result. 
Result so far: 68745.5214723
If we subtract 2445 from 3200, we get 755.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7550, and continue the process.

Advancing to step 16:
815 can be fit into 7550 9 times, resulting in a remainder of 215.
Record the quotient 9 as the next digit in the result. 
Result so far: 68745.52147239
If we subtract 7335 from 7550, we get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

After the division, we end up with 68745.52147239 and a remainder of 2.15e-07.
