We're dividing 545391 by 50 
Let's see how many times 50 fits into 545391.

Step 1:
The number 50 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 50

Advancing to step 2:
50 can be fit into 54 1 times, resulting in a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 50 from 54 leaves us with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 50

Let's proceed to step 3:
If we divide 45 by 50, we get 0 and a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 45 to get 45.
Include the next digit (3) from the dividend after 45, then repeat: 453 / 50

Going ahead to step 4:
If we divide 453 by 50, we get 9 and a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 109.0
The remainder is 3 after subtracting 450 from 453.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 50

Going ahead to step 5:
39 divided by 50 is 0 with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 1090.0
Deduct 0 from 39 and we're left with 39.
Take the next digit (1) from the dividend and append it to 39, then repeat: 391 / 50

Moving on to step 6:
50 goes into 391 7 times with a remainder of 41.
The next digit of our result is 7. 
Result so far: 10907.0
The remainder is 41 after subtracting 350 from 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 7:
If we divide 410 by 50, we get 8 and a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 10907.8
If we subtract 400 from 410, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
The number 50 fits into 100 2 times, leaving a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 10907.82
Subtracting 100 from 100 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
When dividing 0 by 50, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10907.82
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
If we divide 0 by 50, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10907.82
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 10907.82, with a leftover of 0.0.
