We're dividing 545055 by 42 
Our goal is to divide 545055 by 42.

Let's proceed to step 1:
42 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 42

Step 2:
If we divide 54 by 42, we get 1 and a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 42 from 54 leaves us with 12.
Grab the next digit (5) from the dividend, add it to 12, then carry on: 125 / 42

Step 3:
The number 42 fits into 125 2 times, leaving a remainder of 41.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtract 84 from 125 to get 41.
Fetch the next digit (0) from the dividend, attach it to 41 and continue: 410 / 42

Going ahead to step 4:
If we divide 410 by 42, we get 9 and a remainder of 32.
The number 9 becomes the next digit in our result. 
Result so far: 129.0
If we take 378 away from 410, we end up with 32.
Take the next digit (5) from the dividend and append it to 32, then repeat: 325 / 42

Let's proceed to step 5:
42 goes into 325 7 times with a remainder of 31.
The next digit of our result is 7. 
Result so far: 1297.0
Subtracting 294 from 325 leaves us with 31.
Include the next digit (5) from the dividend after 31, then repeat: 315 / 42

Advancing to step 6:
If we divide 315 by 42, we get 7 and a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 12977.0
If we subtract 294 from 315, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 7:
If we divide 210 by 42, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 12977.5
If we take 210 away from 210, we end up 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.

Going ahead to step 8:
If we divide 0 by 42, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 12977.5
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
When dividing 0 by 42, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 12977.5
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.

After the division, we end up with 12977.5 and a remainder of 0.0.
