36193295 ÷ 409 
The aim is to understand the frequency of 409 in 36193295.

Advancing to step 1:
When dividing 3 by 409, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 409

Step 2:
409 can be fit into 36 0 times, resulting in a remainder of 36.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 36 after subtracting 0 from 36.
Bring next digit (1) of the dividend behind the 36 and repeat the process: 361 / 409

Advancing to step 3:
If we divide 361 by 409, we get 0 and a remainder of 361.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 361, we get 361.
Grab the next digit (9) from the dividend, add it to 361, then carry on: 3619 / 409

On to step 4:
The number 409 fits into 3619 8 times, leaving a remainder of 347.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 3272 from 3619 and we're left with 347.
Grab the next digit (3) from the dividend, add it to 347, then carry on: 3473 / 409

Moving on to step 5:
The number 409 fits into 3473 8 times, leaving a remainder of 201.
Use 8 as the next digit of our solution. 
Result so far: 88.0
The remainder is 201 after subtracting 3272 from 3473.
Append the next digit (2) from the dividend to 201 and continue with: 2012 / 409

Going ahead to step 6:
409 can be fit into 2012 4 times, resulting in a remainder of 376.
Record the quotient 4 as the next digit in the result. 
Result so far: 884.0
If we take 1636 away from 2012, we end up with 376.
Bring next digit (9) of the dividend behind the 376 and repeat the process: 3769 / 409

Moving on to step 7:
The number 409 fits into 3769 9 times, leaving a remainder of 88.
Record the quotient 9 as the next digit in the result. 
Result so far: 8849.0
If we take 3681 away from 3769, we end up with 88.
Bring next digit (5) of the dividend behind the 88 and repeat the process: 885 / 409

Advancing to step 8:
If we divide 885 by 409, we get 2 and a remainder of 67.
Put 2 as the next digit of the answer. 
Result so far: 88492.0
If we subtract 818 from 885, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 9:
The number 409 fits into 670 1 times, leaving a remainder of 261.
The number 1 becomes the next digit in our result. 
Result so far: 88492.1
Deduct 409 from 670 and we're left with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Going ahead to step 10:
409 goes into 2610 6 times with a remainder of 156.
Put 6 as the next digit of the answer. 
Result so far: 88492.16
Subtracting 2454 from 2610 leaves us with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Let's proceed to step 11:
409 goes into 1560 3 times with a remainder of 333.
Record the quotient 3 as the next digit in the result. 
Result so far: 88492.163
If we take 1227 away from 1560, we end up with 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

Going ahead to step 12:
3330 divided by 409 is 8 with a remainder of 58.
Put 8 as the next digit of the answer. 
Result so far: 88492.1638
If we take 3272 away from 3330, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 13:
409 can be fit into 580 1 times, resulting in a remainder of 171.
Record the quotient 1 as the next digit in the result. 
Result so far: 88492.16381
Subtracting 409 from 580 leaves us with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

On to step 14:
1710 divided by 409 is 4 with a remainder of 74.
The next digit of our result is 4. 
Result so far: 88492.163814
Subtracting 1636 from 1710 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 15:
If we divide 740 by 409, we get 1 and a remainder of 331.
The number 1 becomes the next digit in our result. 
Result so far: 88492.1638141
Subtract 409 from 740 to get 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Step 16:
3310 divided by 409 is 8 with a remainder of 38.
The next digit of our result is 8. 
Result so far: 88492.16381418
Subtract 3272 from 3310 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

After the division, we end up with 88492.16381418 and a remainder of 3.8e-08.
