15144 ÷ 57 
We're looking to find how many times 57 goes into 15144.

On to step 1:
57 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 57

Going ahead to step 2:
If we divide 15 by 57, we get 0 and a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Bring next digit (1) of the dividend behind the 15 and repeat the process: 151 / 57

Moving on to step 3:
The number 57 fits into 151 2 times, leaving a remainder of 37.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 37 after subtracting 114 from 151.
Take the next digit (4) from the dividend and append it to 37, then repeat: 374 / 57

Let's proceed to step 4:
If we divide 374 by 57, we get 6 and a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
If we take 342 away from 374, we end up with 32.
Grab the next digit (4) from the dividend, add it to 32, then carry on: 324 / 57

Let's proceed to step 5:
The number 57 fits into 324 5 times, leaving a remainder of 39.
Write down 5 as next digit of the result. 
Result so far: 265.0
Subtract 285 from 324 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 6:
The number 57 fits into 390 6 times, leaving a remainder of 48.
The number 6 becomes the next digit in our result. 
Result so far: 265.6
Subtracting 342 from 390 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 7:
57 goes into 480 8 times with a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 265.68
The remainder is 24 after subtracting 456 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 8:
If we divide 240 by 57, we get 4 and a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 265.684
The remainder is 12 after subtracting 228 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 9:
57 goes into 120 2 times with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 265.6842
Subtract 114 from 120 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 10:
The number 57 fits into 60 1 times, leaving a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 265.68421
Subtracting 57 from 60 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 11:
The number 57 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 265.68421
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 12:
The number 57 fits into 300 5 times, leaving a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 265.6842105
If we subtract 285 from 300, 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.

On to step 13:
The number 57 fits into 150 2 times, leaving a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 265.68421052
Deduct 114 from 150 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

After the division, we end up with 265.68421052 and a remainder of 3.6e-08.
