33927161 ÷ 409 
The aim is to understand the frequency of 409 in 33927161.

On to step 1:
409 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
The remainder is 3 after subtracting 0 from 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 409

On to step 2:
33 divided by 409 is 0 with a remainder of 33.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 33 leaves us with 33.
Include the next digit (9) from the dividend after 33, then repeat: 339 / 409

On to step 3:
If we divide 339 by 409, we get 0 and a remainder of 339.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 339 after subtracting 0 from 339.
Append the next digit (2) from the dividend to 339 and continue with: 3392 / 409

Let's proceed to step 4:
When dividing 3392 by 409, we get 8 with a remainder of 120.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 3272 from 3392 and we're left with 120.
Bring next digit (7) of the dividend behind the 120 and repeat the process: 1207 / 409

Step 5:
If we divide 1207 by 409, we get 2 and a remainder of 389.
Put 2 as the next digit of the answer. 
Result so far: 82.0
Subtracting 818 from 1207 leaves us with 389.
Take the next digit (1) from the dividend and append it to 389, then repeat: 3891 / 409

Advancing to step 6:
409 goes into 3891 9 times with a remainder of 210.
Use 9 as the next digit of our solution. 
Result so far: 829.0
Deduct 3681 from 3891 and we're left with 210.
Append the next digit (6) from the dividend to 210 and continue with: 2106 / 409

On to step 7:
The number 409 fits into 2106 5 times, leaving a remainder of 61.
Use 5 as the next digit of our solution. 
Result so far: 8295.0
Subtract 2045 from 2106 to get 61.
Bring next digit (1) of the dividend behind the 61 and repeat the process: 611 / 409

Going ahead to step 8:
When dividing 611 by 409, we get 1 with a remainder of 202.
Use 1 as the next digit of our solution. 
Result so far: 82951.0
Deduct 409 from 611 and we're left with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Moving on to step 9:
If we divide 2020 by 409, we get 4 and a remainder of 384.
The next digit of our result is 4. 
Result so far: 82951.4
Deduct 1636 from 2020 and we're left with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Moving on to step 10:
409 goes into 3840 9 times with a remainder of 159.
Use 9 as the next digit of our solution. 
Result so far: 82951.49
The remainder is 159 after subtracting 3681 from 3840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Going ahead to step 11:
When dividing 1590 by 409, we get 3 with a remainder of 363.
Put 3 as the next digit of the answer. 
Result so far: 82951.493
Deduct 1227 from 1590 and we're left with 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

Going ahead to step 12:
409 goes into 3630 8 times with a remainder of 358.
Record the quotient 8 as the next digit in the result. 
Result so far: 82951.4938
Deduct 3272 from 3630 and we're left with 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Step 13:
3580 divided by 409 is 8 with a remainder of 308.
Write down 8 as next digit of the result. 
Result so far: 82951.49388
Deduct 3272 from 3580 and we're left with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

In conclusion, the division gives 82951.49388 with a balance of 0.000308.
