572784 ÷ 45 
Let's see how many times 45 fits into 572784.

Let's proceed to step 1:
The number 45 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 45

Step 2:
If we divide 57 by 45, we get 1 and a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 45 from 57, we get 12.
Fetch the next digit (2) from the dividend, attach it to 12 and continue: 122 / 45

Going ahead to step 3:
If we divide 122 by 45, we get 2 and a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we take 90 away from 122, we end up with 32.
Append the next digit (7) from the dividend to 32 and continue with: 327 / 45

Step 4:
45 goes into 327 7 times with a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 127.0
Deduct 315 from 327 and we're left with 12.
Fetch the next digit (8) from the dividend, attach it to 12 and continue: 128 / 45

Advancing to step 5:
If we divide 128 by 45, we get 2 and a remainder of 38.
The next digit of our result is 2. 
Result so far: 1272.0
The remainder is 38 after subtracting 90 from 128.
Take the next digit (4) from the dividend and append it to 38, then repeat: 384 / 45

On to step 6:
45 goes into 384 8 times with a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 12728.0
If we take 360 away from 384, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 7:
45 can be fit into 240 5 times, resulting in a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 12728.5
If we subtract 225 from 240, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 8:
The number 45 fits into 150 3 times, leaving a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 12728.53
Deduct 135 from 150 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 9:
If we divide 150 by 45, we get 3 and a remainder of 15.
The next digit of our result is 3. 
Result so far: 12728.533
If we take 135 away from 150, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

After the division, we end up with 12728.533 and a remainder of 0.0015.
