When dividing 13 by 666, we get 0 with a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Bring next digit (0) of the dividend behind the 13 and repeat the process: 130 / 666

Advancing to step 3:
When dividing 130 by 666, we get 0 with a remainder of 130.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 130 leaves us with 130.
Fetch the next digit (9) from the dividend, attach it to 130 and continue: 1309 / 666

Let's proceed to step 4:
666 goes into 1309 1 times with a remainder of 643.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 666 from 1309 to get 643.
Grab the next digit (9) from the dividend, add it to 643, then carry on: 6439 / 666

Moving on to step 5:
When dividing 6439 by 666, we get 9 with a remainder of 445.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Subtract 5994 from 6439 to get 445.
Grab the next digit (4) from the dividend, add it to 445, then carry on: 4454 / 666

Moving on to step 6:
666 can be fit into 4454 6 times, resulting in a remainder of 458.
Write down 6 as next digit of the result. 
Result so far: 196.0
Subtract 3996 from 4454 to get 458.
Append the next digit (9) from the dividend to 458 and continue with: 4589 / 666

Going ahead to step 7:
666 can be fit into 4589 6 times, resulting in a remainder of 593.
Put 6 as the next digit of the answer. 
Result so far: 1966.0
If we subtract 3996 from 4589, we get 593.
Fetch the next digit (3) from the dividend, attach it to 593 and continue: 5933 / 666

Step 8:
When dividing 5933 by 666, we get 8 with a remainder of 605.
The next digit of our result is 8. 
Result so far: 19668.0
Subtracting 5328 from 5933 leaves us with 605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

Moving on to step 9:
666 goes into 6050 9 times with a remainder of 56.
Record the quotient 9 as the next digit in the result. 
Result so far: 19668.9
Subtract 5994 from 6050 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 10:
560 divided by 666 is 0 with a remainder of 560.
Record the quotient 0 as the next digit in the result. 
Result so far: 19668.9
Subtract 0 from 560 to get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Let's proceed to step 11:
If we divide 5600 by 666, we get 8 and a remainder of 272.
Put 8 as the next digit of the answer. 
Result so far: 19668.908
If we subtract 5328 from 5600, we get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Going ahead to step 12:
The number 666 fits into 2720 4 times, leaving a remainder of 56.
The next digit of our result is 4. 
Result so far: 19668.9084
The remainder is 56 after subtracting 2664 from 2720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 13:
666 can be fit into 560 0 times, resulting in a remainder of 560.
Use 0 as the next digit of our solution. 
Result so far: 19668.9084
The remainder is 560 after subtracting 0 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Moving on to step 14:
The number 666 fits into 5600 8 times, leaving a remainder of 272.
Write down 8 as next digit of the result. 
Result so far: 19668.908408
Subtracting 5328 from 5600 leaves us with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Advancing to step 15:
666 goes into 2720 4 times with a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 19668.9084084
If we subtract 2664 from 2720, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 16:
When dividing 560 by 666, we get 0 with a remainder of 560.
Record the quotient 0 as the next digit in the result. 
Result so far: 19668.9084084
If we subtract 0 from 560, we get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.
