We're dividing 12993846 by 666 
We want to figure out the number of times 12993846 can be divided by 666.

Moving on to step 1:
666 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
If we take 0 away from 1, we end up with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 666

On to step 2:
666 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
If we take 0 away from 12, we end up with 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 666

Step 3:
When dividing 129 by 666, we get 0 with a remainder of 129.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 129 to get 129.
Take the next digit (9) from the dividend and append it to 129, then repeat: 1299 / 666

Going ahead to step 4:
666 can be fit into 1299 1 times, resulting in a remainder of 633.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 666 from 1299 leaves us with 633.
Bring next digit (3) of the dividend behind the 633 and repeat the process: 6333 / 666

Advancing to step 5:
The number 666 fits into 6333 9 times, leaving a remainder of 339.
The next digit of our result is 9. 
Result so far: 19.0
Subtract 5994 from 6333 to get 339.
Include the next digit (8) from the dividend after 339, then repeat: 3398 / 666

Moving on to step 6:
666 can be fit into 3398 5 times, resulting in a remainder of 68.
Put 5 as the next digit of the answer. 
Result so far: 195.0
If we subtract 3330 from 3398, we get 68.
Append the next digit (4) from the dividend to 68 and continue with: 684 / 666

Step 7:
When dividing 684 by 666, we get 1 with a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 1951.0
If we subtract 666 from 684, we get 18.
Fetch the next digit (6) from the dividend, attach it to 18 and continue: 186 / 666

Going ahead to step 8:
666 can be fit into 186 0 times, resulting in a remainder of 186.
Write down 0 as next digit of the result. 
Result so far: 19510.0
Subtracting 0 from 186 leaves us with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Let's proceed to step 9:
666 can be fit into 1860 2 times, resulting in a remainder of 528.
Put 2 as the next digit of the answer. 
Result so far: 19510.2
If we subtract 1332 from 1860, we get 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

On to step 10:
The number 666 fits into 5280 7 times, leaving a remainder of 618.
Write down 7 as next digit of the result. 
Result so far: 19510.27
The remainder is 618 after subtracting 4662 from 5280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

On to step 11:
If we divide 6180 by 666, we get 9 and a remainder of 186.
Record the quotient 9 as the next digit in the result. 
Result so far: 19510.279
If we subtract 5994 from 6180, we get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Let's proceed to step 12:
The number 666 fits into 1860 2 times, leaving a remainder of 528.
The number 2 becomes the next digit in our result. 
Result so far: 19510.2792
Deduct 1332 from 1860 and we're left with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

On to step 13:
666 can be fit into 5280 7 times, resulting in a remainder of 618.
The number 7 becomes the next digit in our result. 
Result so far: 19510.27927
Subtracting 4662 from 5280 leaves us with 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

Step 14:
If we divide 6180 by 666, we get 9 and a remainder of 186.
Put 9 as the next digit of the answer. 
Result so far: 19510.279279
Deduct 5994 from 6180 and we're left with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Moving on to step 15:
The number 666 fits into 1860 2 times, leaving a remainder of 528.
Record the quotient 2 as the next digit in the result. 
Result so far: 19510.2792792
If we subtract 1332 from 1860, we get 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Let's proceed to step 16:
666 goes into 5280 7 times with a remainder of 618.
Put 7 as the next digit of the answer. 
Result so far: 19510.27927927
Deduct 4662 from 5280 and we're left with 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

In conclusion, the division gives 19510.27927927 with a balance of 6.18e-07.
