12117300 divided by 409 
Let's see how many times 409 fits into 12117300.

Moving on to step 1:
1 divided by 409 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 409

Step 2:
409 goes into 12 0 times with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 409

Step 3:
The number 409 fits into 121 0 times, leaving a remainder of 121.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 121 and we're left with 121.
Take the next digit (1) from the dividend and append it to 121, then repeat: 1211 / 409

On to step 4:
409 can be fit into 1211 2 times, resulting in a remainder of 393.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 818 from 1211 to get 393.
Bring next digit (7) of the dividend behind the 393 and repeat the process: 3937 / 409

Advancing to step 5:
409 can be fit into 3937 9 times, resulting in a remainder of 256.
Put 9 as the next digit of the answer. 
Result so far: 29.0
Subtracting 3681 from 3937 leaves us with 256.
Include the next digit (3) from the dividend after 256, then repeat: 2563 / 409

Moving on to step 6:
If we divide 2563 by 409, we get 6 and a remainder of 109.
Write down 6 as next digit of the result. 
Result so far: 296.0
The remainder is 109 after subtracting 2454 from 2563.
Bring next digit (0) of the dividend behind the 109 and repeat the process: 1090 / 409

Let's proceed to step 7:
409 goes into 1090 2 times with a remainder of 272.
Put 2 as the next digit of the answer. 
Result so far: 2962.0
The remainder is 272 after subtracting 818 from 1090.
Include the next digit (0) from the dividend after 272, then repeat: 2720 / 409

On to step 8:
If we divide 2720 by 409, we get 6 and a remainder of 266.
Use 6 as the next digit of our solution. 
Result so far: 29626.0
If we subtract 2454 from 2720, we get 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Moving on to step 9:
409 can be fit into 2660 6 times, resulting in a remainder of 206.
The next digit of our result is 6. 
Result so far: 29626.6
If we take 2454 away from 2660, we end up with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Going ahead to step 10:
2060 divided by 409 is 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 29626.65
Subtract 2045 from 2060 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 11:
409 goes into 150 0 times with a remainder of 150.
The next digit of our result is 0. 
Result so far: 29626.65
If we subtract 0 from 150, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 12:
1500 divided by 409 is 3 with a remainder of 273.
Use 3 as the next digit of our solution. 
Result so far: 29626.6503
Subtract 1227 from 1500 to get 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

On to step 13:
When dividing 2730 by 409, we get 6 with a remainder of 276.
The number 6 becomes the next digit in our result. 
Result so far: 29626.65036
Deduct 2454 from 2730 and we're left with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Advancing to step 14:
The number 409 fits into 2760 6 times, leaving a remainder of 306.
The next digit of our result is 6. 
Result so far: 29626.650366
The remainder is 306 after subtracting 2454 from 2760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

The final outcome is 29626.650366, with a leftover of 3.06e-05.
