We divide 30844070 by 815
The aim is to understand the frequency of 815 in 30844070.

Advancing to step 1:
815 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 815

On to step 2:
When dividing 30 by 815, we get 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Include the next digit (8) from the dividend after 30, then repeat: 308 / 815

On to step 3:
If we divide 308 by 815, we get 0 and a remainder of 308.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 308, we get 308.
Bring next digit (4) of the dividend behind the 308 and repeat the process: 3084 / 815

On to step 4:
815 can be fit into 3084 3 times, resulting in a remainder of 639.
The next digit of our result is 3. 
Result so far: 3.0
If we take 2445 away from 3084, we end up with 639.
Grab the next digit (4) from the dividend, add it to 639, then carry on: 6394 / 815

Going ahead to step 5:
When dividing 6394 by 815, we get 7 with a remainder of 689.
Write down 7 as next digit of the result. 
Result so far: 37.0
Subtracting 5705 from 6394 leaves us with 689.
Take the next digit (0) from the dividend and append it to 689, then repeat: 6890 / 815

Moving on to step 6:
815 can be fit into 6890 8 times, resulting in a remainder of 370.
Use 8 as the next digit of our solution. 
Result so far: 378.0
The remainder is 370 after subtracting 6520 from 6890.
Include the next digit (7) from the dividend after 370, then repeat: 3707 / 815

Going ahead to step 7:
When dividing 3707 by 815, we get 4 with a remainder of 447.
Record the quotient 4 as the next digit in the result. 
Result so far: 3784.0
If we subtract 3260 from 3707, we get 447.
Fetch the next digit (0) from the dividend, attach it to 447 and continue: 4470 / 815

Step 8:
If we divide 4470 by 815, we get 5 and a remainder of 395.
The next digit of our result is 5. 
Result so far: 37845.0
Subtracting 4075 from 4470 leaves us with 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Moving on to step 9:
If we divide 3950 by 815, we get 4 and a remainder of 690.
The next digit of our result is 4. 
Result so far: 37845.4
The remainder is 690 after subtracting 3260 from 3950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

Going ahead to step 10:
When dividing 6900 by 815, we get 8 with a remainder of 380.
The number 8 becomes the next digit in our result. 
Result so far: 37845.48
Subtracting 6520 from 6900 leaves us with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Moving on to step 11:
815 goes into 3800 4 times with a remainder of 540.
Use 4 as the next digit of our solution. 
Result so far: 37845.484
If we take 3260 away from 3800, we end up with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Moving on to step 12:
When dividing 5400 by 815, we get 6 with a remainder of 510.
Use 6 as the next digit of our solution. 
Result so far: 37845.4846
If we take 4890 away from 5400, we end up with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

On to step 13:
815 can be fit into 5100 6 times, resulting in a remainder of 210.
Use 6 as the next digit of our solution. 
Result so far: 37845.48466
Subtracting 4890 from 5100 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

The final outcome is 37845.48466, with a leftover of 0.00021.
