Let's divide 55051884 by 409
We're looking to find how many times 409 goes into 55051884.

Advancing to step 1:
When dividing 5 by 409, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 409

Step 2:
55 divided by 409 is 0 with a remainder of 55.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 55 after subtracting 0 from 55.
Append the next digit (0) from the dividend to 55 and continue with: 550 / 409

Advancing to step 3:
409 can be fit into 550 1 times, resulting in a remainder of 141.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 141 after subtracting 409 from 550.
Grab the next digit (5) from the dividend, add it to 141, then carry on: 1415 / 409

Moving on to step 4:
If we divide 1415 by 409, we get 3 and a remainder of 188.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we take 1227 away from 1415, we end up with 188.
Bring next digit (1) of the dividend behind the 188 and repeat the process: 1881 / 409

On to step 5:
If we divide 1881 by 409, we get 4 and a remainder of 245.
Record the quotient 4 as the next digit in the result. 
Result so far: 134.0
If we subtract 1636 from 1881, we get 245.
Include the next digit (8) from the dividend after 245, then repeat: 2458 / 409

Going ahead to step 6:
409 goes into 2458 6 times with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 1346.0
Deduct 2454 from 2458 and we're left with 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 409

Step 7:
If we divide 48 by 409, we get 0 and a remainder of 48.
The next digit of our result is 0. 
Result so far: 13460.0
Subtracting 0 from 48 leaves us with 48.
Append the next digit (4) from the dividend to 48 and continue with: 484 / 409

Going ahead to step 8:
The number 409 fits into 484 1 times, leaving a remainder of 75.
Write down 1 as next digit of the result. 
Result so far: 134601.0
If we take 409 away from 484, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 9:
409 can be fit into 750 1 times, resulting in a remainder of 341.
The next digit of our result is 1. 
Result so far: 134601.1
Subtract 409 from 750 to get 341.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Going ahead to step 10:
If we divide 3410 by 409, we get 8 and a remainder of 138.
The number 8 becomes the next digit in our result. 
Result so far: 134601.18
If we take 3272 away from 3410, we end up with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Advancing to step 11:
When dividing 1380 by 409, we get 3 with a remainder of 153.
Use 3 as the next digit of our solution. 
Result so far: 134601.183
Deduct 1227 from 1380 and we're left with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Moving on to step 12:
When dividing 1530 by 409, we get 3 with a remainder of 303.
Use 3 as the next digit of our solution. 
Result so far: 134601.1833
Deduct 1227 from 1530 and we're left with 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

The final outcome is 134601.1833, with a leftover of 0.00303.
