12552568 ÷ 668 
We want to divide 12552568 by 668.

Step 1:
The number 668 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 668

Moving on to step 2:
668 goes into 12 0 times with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Fetch the next digit (5) from the dividend, attach it to 12 and continue: 125 / 668

Moving on to step 3:
125 divided by 668 is 0 with a remainder of 125.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 125 after subtracting 0 from 125.
Include the next digit (5) from the dividend after 125, then repeat: 1255 / 668

Moving on to step 4:
1255 divided by 668 is 1 with a remainder of 587.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 668 from 1255, we get 587.
Fetch the next digit (2) from the dividend, attach it to 587 and continue: 5872 / 668

Moving on to step 5:
668 can be fit into 5872 8 times, resulting in a remainder of 528.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Subtracting 5344 from 5872 leaves us with 528.
Include the next digit (5) from the dividend after 528, then repeat: 5285 / 668

Let's proceed to step 6:
The number 668 fits into 5285 7 times, leaving a remainder of 609.
The number 7 becomes the next digit in our result. 
Result so far: 187.0
Subtract 4676 from 5285 to get 609.
Include the next digit (6) from the dividend after 609, then repeat: 6096 / 668

Let's proceed to step 7:
When dividing 6096 by 668, we get 9 with a remainder of 84.
The number 9 becomes the next digit in our result. 
Result so far: 1879.0
The remainder is 84 after subtracting 6012 from 6096.
Include the next digit (8) from the dividend after 84, then repeat: 848 / 668

On to step 8:
If we divide 848 by 668, we get 1 and a remainder of 180.
Record the quotient 1 as the next digit in the result. 
Result so far: 18791.0
If we subtract 668 from 848, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 9:
668 can be fit into 1800 2 times, resulting in a remainder of 464.
Record the quotient 2 as the next digit in the result. 
Result so far: 18791.2
Subtracting 1336 from 1800 leaves us with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Advancing to step 10:
668 goes into 4640 6 times with a remainder of 632.
Record the quotient 6 as the next digit in the result. 
Result so far: 18791.26
Subtract 4008 from 4640 to get 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6320, and continue the process.

Let's proceed to step 11:
The number 668 fits into 6320 9 times, leaving a remainder of 308.
The next digit of our result is 9. 
Result so far: 18791.269
The remainder is 308 after subtracting 6012 from 6320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Let's proceed to step 12:
If we divide 3080 by 668, we get 4 and a remainder of 408.
Use 4 as the next digit of our solution. 
Result so far: 18791.2694
If we take 2672 away from 3080, we end up with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Let's proceed to step 13:
668 goes into 4080 6 times with a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 18791.26946
Subtracting 4008 from 4080 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 14:
668 goes into 720 1 times with a remainder of 52.
Put 1 as the next digit of the answer. 
Result so far: 18791.269461
The remainder is 52 after subtracting 668 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 15:
668 goes into 520 0 times with a remainder of 520.
Record the quotient 0 as the next digit in the result. 
Result so far: 18791.269461
Subtracting 0 from 520 leaves us with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 16:
If we divide 5200 by 668, we get 7 and a remainder of 524.
The number 7 becomes the next digit in our result. 
Result so far: 18791.26946107
Subtract 4676 from 5200 to get 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

The quotient of the division is 18791.26946107, and the remainder is 5.24e-07.
