55525842 ÷ 409 
Our goal is to divide 55525842 by 409.

Going ahead to step 1:
The number 409 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 409

Advancing to step 2:
The number 409 fits into 55 0 times, leaving 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.
Include the next digit (5) from the dividend after 55, then repeat: 555 / 409

Let's proceed to step 3:
If we divide 555 by 409, we get 1 and a remainder of 146.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 409 from 555 to get 146.
Take the next digit (2) from the dividend and append it to 146, then repeat: 1462 / 409

Step 4:
1462 divided by 409 is 3 with a remainder of 235.
The next digit of our result is 3. 
Result so far: 13.0
The remainder is 235 after subtracting 1227 from 1462.
Bring next digit (5) of the dividend behind the 235 and repeat the process: 2355 / 409

Step 5:
409 goes into 2355 5 times with a remainder of 310.
Use 5 as the next digit of our solution. 
Result so far: 135.0
Subtracting 2045 from 2355 leaves us with 310.
Include the next digit (8) from the dividend after 310, then repeat: 3108 / 409

Moving on to step 6:
3108 divided by 409 is 7 with a remainder of 245.
Use 7 as the next digit of our solution. 
Result so far: 1357.0
Subtracting 2863 from 3108 leaves us with 245.
Fetch the next digit (4) from the dividend, attach it to 245 and continue: 2454 / 409

Moving on to step 7:
409 goes into 2454 6 times with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 13576.0
Subtract 2454 from 2454 to get 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 409

Moving on to step 8:
If we divide 2 by 409, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 135760.0
If we take 0 away from 2, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
If we divide 20 by 409, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 135760.0
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 10:
The number 409 fits into 200 0 times, leaving a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 135760.0
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final result is 135760.0 with a remainder of 0.2.
