We divide 12615 by 57
We want to figure out the number of times 12615 can be divided by 57.

Advancing to step 1:
57 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 57

Advancing to step 2:
57 can be fit into 12 0 times, resulting in a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Bring next digit (6) of the dividend behind the 12 and repeat the process: 126 / 57

Step 3:
The number 57 fits into 126 2 times, leaving a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 12 after subtracting 114 from 126.
Bring next digit (1) of the dividend behind the 12 and repeat the process: 121 / 57

Let's proceed to step 4:
When dividing 121 by 57, we get 2 with a remainder of 7.
The next digit of our result is 2. 
Result so far: 22.0
Subtract 114 from 121 to get 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 57

Going ahead to step 5:
When dividing 75 by 57, we get 1 with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 221.0
Subtract 57 from 75 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 6:
When dividing 180 by 57, we get 3 with a remainder of 9.
The next digit of our result is 3. 
Result so far: 221.3
Deduct 171 from 180 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
90 divided by 57 is 1 with a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 221.31
The remainder is 33 after subtracting 57 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 8:
The number 57 fits into 330 5 times, leaving a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 221.315
The remainder is 45 after subtracting 285 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 9:
When dividing 450 by 57, we get 7 with a remainder of 51.
Use 7 as the next digit of our solution. 
Result so far: 221.3157
Subtracting 399 from 450 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 10:
57 goes into 510 8 times with a remainder of 54.
Use 8 as the next digit of our solution. 
Result so far: 221.31578
If we subtract 456 from 510, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 11:
The number 57 fits into 540 9 times, leaving a remainder of 27.
The number 9 becomes the next digit in our result. 
Result so far: 221.315789
Subtract 513 from 540 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 12:
270 divided by 57 is 4 with a remainder of 42.
Use 4 as the next digit of our solution. 
Result so far: 221.3157894
Subtract 228 from 270 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 13:
The number 57 fits into 420 7 times, leaving a remainder of 21.
Put 7 as the next digit of the answer. 
Result so far: 221.31578947
If we take 399 away from 420, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The quotient of the division is 221.31578947, and the remainder is 2.1e-08.
