We're dividing 57480552 by 287 
We want to figure out the number of times 57480552 can be divided by 287.

Step 1:
287 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 287

Advancing to step 2:
57 divided by 287 is 0 with a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 57 to get 57.
Bring next digit (4) of the dividend behind the 57 and repeat the process: 574 / 287

On to step 3:
The number 287 fits into 574 2 times, leaving a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 0 after subtracting 574 from 574.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 287

Advancing to step 4:
287 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
If we subtract 0 from 8, we get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 287

Let's proceed to step 5:
If we divide 80 by 287, we get 0 and a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 200.0
Subtract 0 from 80 to get 80.
Bring next digit (5) of the dividend behind the 80 and repeat the process: 805 / 287

Moving on to step 6:
The number 287 fits into 805 2 times, leaving a remainder of 231.
Write down 2 as next digit of the result. 
Result so far: 2002.0
Subtract 574 from 805 to get 231.
Fetch the next digit (5) from the dividend, attach it to 231 and continue: 2315 / 287

Moving on to step 7:
The number 287 fits into 2315 8 times, leaving a remainder of 19.
Record the quotient 8 as the next digit in the result. 
Result so far: 20028.0
Subtract 2296 from 2315 to get 19.
Grab the next digit (2) from the dividend, add it to 19, then carry on: 192 / 287

Going ahead to step 8:
If we divide 192 by 287, we get 0 and a remainder of 192.
The next digit of our result is 0. 
Result so far: 200280.0
Subtract 0 from 192 to get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Step 9:
1920 divided by 287 is 6 with a remainder of 198.
The number 6 becomes the next digit in our result. 
Result so far: 200280.6
If we subtract 1722 from 1920, we get 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Advancing to step 10:
If we divide 1980 by 287, we get 6 and a remainder of 258.
The number 6 becomes the next digit in our result. 
Result so far: 200280.66
If we take 1722 away from 1980, we end up with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

The final result is 200280.66 with a remainder of 0.258.
