570138 ÷ 45 
Let's see how many times 45 fits into 570138.

Let's proceed to step 1:
When dividing 5 by 45, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
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 / 45

Advancing to step 2:
The number 45 fits into 57 1 times, leaving a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 45 from 57, we get 12.
Fetch the next digit (0) from the dividend, attach it to 12 and continue: 120 / 45

Step 3:
45 can be fit into 120 2 times, resulting in a remainder of 30.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 90 from 120 and we're left with 30.
Include the next digit (1) from the dividend after 30, then repeat: 301 / 45

Moving on to step 4:
If we divide 301 by 45, we get 6 and a remainder of 31.
Write down 6 as next digit of the result. 
Result so far: 126.0
If we take 270 away from 301, we end up with 31.
Grab the next digit (3) from the dividend, add it to 31, then carry on: 313 / 45

Going ahead to step 5:
The number 45 fits into 313 6 times, leaving a remainder of 43.
Write down 6 as next digit of the result. 
Result so far: 1266.0
If we take 270 away from 313, we end up with 43.
Grab the next digit (8) from the dividend, add it to 43, then carry on: 438 / 45

Moving on to step 6:
45 can be fit into 438 9 times, resulting in a remainder of 33.
Use 9 as the next digit of our solution. 
Result so far: 12669.0
The remainder is 33 after subtracting 405 from 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 7:
If we divide 330 by 45, we get 7 and a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 12669.7
Subtract 315 from 330 to 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.

Going ahead to step 8:
150 divided by 45 is 3 with a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 12669.73
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.

On to step 9:
150 divided by 45 is 3 with a remainder of 15.
The next digit of our result is 3. 
Result so far: 12669.733
Subtract 135 from 150 to 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.

The quotient of the division is 12669.733, and the remainder is 0.0015.
