We're dividing 33950676 by 815 
The aim is to understand the frequency of 815 in 33950676.

On to step 1:
The number 815 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 815

Let's proceed to step 2:
The number 815 fits into 33 0 times, leaving a remainder of 33.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 33 after subtracting 0 from 33.
Grab the next digit (9) from the dividend, add it to 33, then carry on: 339 / 815

Moving on to step 3:
The number 815 fits into 339 0 times, leaving a remainder of 339.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 339 and we're left with 339.
Include the next digit (5) from the dividend after 339, then repeat: 3395 / 815

Moving on to step 4:
3395 divided by 815 is 4 with a remainder of 135.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 3260 away from 3395, we end up with 135.
Take the next digit (0) from the dividend and append it to 135, then repeat: 1350 / 815

Going ahead to step 5:
If we divide 1350 by 815, we get 1 and a remainder of 535.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
Subtract 815 from 1350 to get 535.
Bring next digit (6) of the dividend behind the 535 and repeat the process: 5356 / 815

Going ahead to step 6:
815 goes into 5356 6 times with a remainder of 466.
Put 6 as the next digit of the answer. 
Result so far: 416.0
If we take 4890 away from 5356, we end up with 466.
Bring next digit (7) of the dividend behind the 466 and repeat the process: 4667 / 815

Step 7:
815 can be fit into 4667 5 times, resulting in a remainder of 592.
The next digit of our result is 5. 
Result so far: 4165.0
Subtract 4075 from 4667 to get 592.
Append the next digit (6) from the dividend to 592 and continue with: 5926 / 815

On to step 8:
815 can be fit into 5926 7 times, resulting in a remainder of 221.
The number 7 becomes the next digit in our result. 
Result so far: 41657.0
Subtract 5705 from 5926 to get 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Moving on to step 9:
815 goes into 2210 2 times with a remainder of 580.
The next digit of our result is 2. 
Result so far: 41657.2
Subtract 1630 from 2210 to get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Moving on to step 10:
When dividing 5800 by 815, we get 7 with a remainder of 95.
The next digit of our result is 7. 
Result so far: 41657.27
If we subtract 5705 from 5800, we get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

On to step 11:
The number 815 fits into 950 1 times, leaving a remainder of 135.
Use 1 as the next digit of our solution. 
Result so far: 41657.271
The remainder is 135 after subtracting 815 from 950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Advancing to step 12:
815 goes into 1350 1 times with a remainder of 535.
Write down 1 as next digit of the result. 
Result so far: 41657.2711
If we subtract 815 from 1350, we get 535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

The final outcome is 41657.2711, with a leftover of 0.00535.
