55242611 divided by 409 
We want to divide 55242611 by 409.

On to step 1:
If we divide 5 by 409, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 409

Step 2:
If we divide 55 by 409, we get 0 and a remainder of 55.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 55 leaves us with 55.
Include the next digit (2) from the dividend after 55, then repeat: 552 / 409

Advancing to step 3:
409 can be fit into 552 1 times, resulting in a remainder of 143.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 409 from 552 and we're left with 143.
Append the next digit (4) from the dividend to 143 and continue with: 1434 / 409

Let's proceed to step 4:
The number 409 fits into 1434 3 times, leaving a remainder of 207.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtract 1227 from 1434 to get 207.
Append the next digit (2) from the dividend to 207 and continue with: 2072 / 409

Moving on to step 5:
409 can be fit into 2072 5 times, resulting in a remainder of 27.
The next digit of our result is 5. 
Result so far: 135.0
Subtracting 2045 from 2072 leaves us with 27.
Grab the next digit (6) from the dividend, add it to 27, then carry on: 276 / 409

Moving on to step 6:
The number 409 fits into 276 0 times, leaving a remainder of 276.
Put 0 as the next digit of the answer. 
Result so far: 1350.0
The remainder is 276 after subtracting 0 from 276.
Take the next digit (1) from the dividend and append it to 276, then repeat: 2761 / 409

Step 7:
2761 divided by 409 is 6 with a remainder of 307.
Use 6 as the next digit of our solution. 
Result so far: 13506.0
Deduct 2454 from 2761 and we're left with 307.
Append the next digit (1) from the dividend to 307 and continue with: 3071 / 409

Going ahead to step 8:
409 can be fit into 3071 7 times, resulting in a remainder of 208.
Write down 7 as next digit of the result. 
Result so far: 135067.0
Subtracting 2863 from 3071 leaves us with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

On to step 9:
409 goes into 2080 5 times with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 135067.5
Subtracting 2045 from 2080 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 10:
If we divide 350 by 409, we get 0 and a remainder of 350.
Write down 0 as next digit of the result. 
Result so far: 135067.5
If we subtract 0 from 350, we get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Going ahead to step 11:
409 can be fit into 3500 8 times, resulting in a remainder of 228.
Write down 8 as next digit of the result. 
Result so far: 135067.508
Subtracting 3272 from 3500 leaves us with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Advancing to step 12:
The number 409 fits into 2280 5 times, leaving a remainder of 235.
The number 5 becomes the next digit in our result. 
Result so far: 135067.5085
If we subtract 2045 from 2280, we get 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Step 13:
If we divide 2350 by 409, we get 5 and a remainder of 305.
The next digit of our result is 5. 
Result so far: 135067.50855
Subtract 2045 from 2350 to get 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

After the division, we end up with 135067.50855 and a remainder of 0.000305.
