55425919 ÷ 440 
We want to figure out the number of times 55425919 can be divided by 440.

On to step 1:
440 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 440

Step 2:
The number 440 fits into 55 0 times, leaving a remainder of 55.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 55 to get 55.
Include the next digit (4) from the dividend after 55, then repeat: 554 / 440

Advancing to step 3:
440 can be fit into 554 1 times, resulting in a remainder of 114.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 114 after subtracting 440 from 554.
Append the next digit (2) from the dividend to 114 and continue with: 1142 / 440

Going ahead to step 4:
The number 440 fits into 1142 2 times, leaving a remainder of 262.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 880 from 1142 leaves us with 262.
Include the next digit (5) from the dividend after 262, then repeat: 2625 / 440

Advancing to step 5:
440 goes into 2625 5 times with a remainder of 425.
The number 5 becomes the next digit in our result. 
Result so far: 125.0
Subtract 2200 from 2625 to get 425.
Bring next digit (9) of the dividend behind the 425 and repeat the process: 4259 / 440

On to step 6:
440 goes into 4259 9 times with a remainder of 299.
The number 9 becomes the next digit in our result. 
Result so far: 1259.0
Subtract 3960 from 4259 to get 299.
Bring next digit (1) of the dividend behind the 299 and repeat the process: 2991 / 440

Moving on to step 7:
When dividing 2991 by 440, we get 6 with a remainder of 351.
Use 6 as the next digit of our solution. 
Result so far: 12596.0
Deduct 2640 from 2991 and we're left with 351.
Take the next digit (9) from the dividend and append it to 351, then repeat: 3519 / 440

Going ahead to step 8:
440 can be fit into 3519 7 times, resulting in a remainder of 439.
The next digit of our result is 7. 
Result so far: 125967.0
If we subtract 3080 from 3519, we get 439.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4390, and continue the process.

Going ahead to step 9:
The number 440 fits into 4390 9 times, leaving a remainder of 430.
The next digit of our result is 9. 
Result so far: 125967.9
Subtracting 3960 from 4390 leaves us with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Advancing to step 10:
440 goes into 4300 9 times with a remainder of 340.
Record the quotient 9 as the next digit in the result. 
Result so far: 125967.99
Subtracting 3960 from 4300 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Our division results in 125967.99 with a remaining 0.34.
