12486668 divided by 629 
We want to divide 12486668 by 629.

Let's proceed to step 1:
When dividing 1 by 629, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 629

Step 2:
12 divided by 629 is 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Grab the next digit (4) from the dividend, add it to 12, then carry on: 124 / 629

Let's proceed to step 3:
629 goes into 124 0 times with a remainder of 124.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 124, we end up with 124.
Append the next digit (8) from the dividend to 124 and continue with: 1248 / 629

Advancing to step 4:
1248 divided by 629 is 1 with a remainder of 619.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 629 from 1248 leaves us with 619.
Append the next digit (6) from the dividend to 619 and continue with: 6196 / 629

Let's proceed to step 5:
629 goes into 6196 9 times with a remainder of 535.
The next digit of our result is 9. 
Result so far: 19.0
Subtract 5661 from 6196 to get 535.
Fetch the next digit (6) from the dividend, attach it to 535 and continue: 5356 / 629

Going ahead to step 6:
5356 divided by 629 is 8 with a remainder of 324.
Write down 8 as next digit of the result. 
Result so far: 198.0
If we subtract 5032 from 5356, we get 324.
Bring next digit (6) of the dividend behind the 324 and repeat the process: 3246 / 629

Advancing to step 7:
3246 divided by 629 is 5 with a remainder of 101.
The number 5 becomes the next digit in our result. 
Result so far: 1985.0
Deduct 3145 from 3246 and we're left with 101.
Take the next digit (8) from the dividend and append it to 101, then repeat: 1018 / 629

Moving on to step 8:
1018 divided by 629 is 1 with a remainder of 389.
The next digit of our result is 1. 
Result so far: 19851.0
Deduct 629 from 1018 and we're left with 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

Step 9:
The number 629 fits into 3890 6 times, leaving a remainder of 116.
Use 6 as the next digit of our solution. 
Result so far: 19851.6
If we subtract 3774 from 3890, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Moving on to step 10:
1160 divided by 629 is 1 with a remainder of 531.
The number 1 becomes the next digit in our result. 
Result so far: 19851.61
If we take 629 away from 1160, we end up with 531.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5310, and continue the process.

Going ahead to step 11:
629 goes into 5310 8 times with a remainder of 278.
Write down 8 as next digit of the result. 
Result so far: 19851.618
Subtract 5032 from 5310 to get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Going ahead to step 12:
The number 629 fits into 2780 4 times, leaving a remainder of 264.
Record the quotient 4 as the next digit in the result. 
Result so far: 19851.6184
The remainder is 264 after subtracting 2516 from 2780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Step 13:
629 goes into 2640 4 times with a remainder of 124.
Use 4 as the next digit of our solution. 
Result so far: 19851.61844
If we take 2516 away from 2640, we end up with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

After the division, we end up with 19851.61844 and a remainder of 0.000124.
