19047826 ÷ 815 
The aim is to understand the frequency of 815 in 19047826.

Step 1:
The number 815 fits into 1 0 times, leaving 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.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 815

Let's proceed to step 2:
If we divide 19 by 815, we get 0 and a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 19, we get 19.
Fetch the next digit (0) from the dividend, attach it to 19 and continue: 190 / 815

On to step 3:
190 divided by 815 is 0 with a remainder of 190.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 190 to get 190.
Include the next digit (4) from the dividend after 190, then repeat: 1904 / 815

On to step 4:
1904 divided by 815 is 2 with a remainder of 274.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 1630 from 1904, we get 274.
Grab the next digit (7) from the dividend, add it to 274, then carry on: 2747 / 815

Going ahead to step 5:
815 can be fit into 2747 3 times, resulting in a remainder of 302.
Put 3 as the next digit of the answer. 
Result so far: 23.0
Subtracting 2445 from 2747 leaves us with 302.
Grab the next digit (8) from the dividend, add it to 302, then carry on: 3028 / 815

Going ahead to step 6:
When dividing 3028 by 815, we get 3 with a remainder of 583.
The next digit of our result is 3. 
Result so far: 233.0
If we subtract 2445 from 3028, we get 583.
Bring next digit (2) of the dividend behind the 583 and repeat the process: 5832 / 815

Going ahead to step 7:
The number 815 fits into 5832 7 times, leaving a remainder of 127.
Use 7 as the next digit of our solution. 
Result so far: 2337.0
Subtract 5705 from 5832 to get 127.
Fetch the next digit (6) from the dividend, attach it to 127 and continue: 1276 / 815

Moving on to step 8:
If we divide 1276 by 815, we get 1 and a remainder of 461.
Put 1 as the next digit of the answer. 
Result so far: 23371.0
Subtracting 815 from 1276 leaves us with 461.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4610, and continue the process.

Let's proceed to step 9:
When dividing 4610 by 815, we get 5 with a remainder of 535.
Write down 5 as next digit of the result. 
Result so far: 23371.5
The remainder is 535 after subtracting 4075 from 4610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

On to step 10:
The number 815 fits into 5350 6 times, leaving a remainder of 460.
The next digit of our result is 6. 
Result so far: 23371.56
Subtracting 4890 from 5350 leaves us with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

On to step 11:
815 goes into 4600 5 times with a remainder of 525.
Use 5 as the next digit of our solution. 
Result so far: 23371.565
If we take 4075 away from 4600, we end up with 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

On to step 12:
If we divide 5250 by 815, we get 6 and a remainder of 360.
The number 6 becomes the next digit in our result. 
Result so far: 23371.5656
The remainder is 360 after subtracting 4890 from 5250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 13:
If we divide 3600 by 815, we get 4 and a remainder of 340.
Write down 4 as next digit of the result. 
Result so far: 23371.56564
Deduct 3260 from 3600 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Advancing to step 14:
815 can be fit into 3400 4 times, resulting in a remainder of 140.
Record the quotient 4 as the next digit in the result. 
Result so far: 23371.565644
If we subtract 3260 from 3400, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

The final result is 23371.565644 with a remainder of 1.4e-05.
