999666 divided by 13 
Let's see how many times 13 fits into 999666.

Going ahead to step 1:
The number 13 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 13

Moving on to step 2:
If we divide 99 by 13, we get 7 and a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 91 from 99 and we're left with 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 13

Advancing to step 3:
The number 13 fits into 89 6 times, leaving a remainder of 11.
Record the quotient 6 as the next digit in the result. 
Result so far: 76.0
Subtract 78 from 89 to get 11.
Include the next digit (6) from the dividend after 11, then repeat: 116 / 13

On to step 4:
When dividing 116 by 13, we get 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 768.0
Deduct 104 from 116 and we're left with 12.
Include the next digit (6) from the dividend after 12, then repeat: 126 / 13

Let's proceed to step 5:
13 can be fit into 126 9 times, resulting in a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 7689.0
If we subtract 117 from 126, we get 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 13

Going ahead to step 6:
13 goes into 96 7 times with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 76897.0
If we subtract 91 from 96, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
50 divided by 13 is 3 with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 76897.3
If we subtract 39 from 50, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 8:
When dividing 110 by 13, we get 8 with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 76897.38
Subtracting 104 from 110 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 9:
13 goes into 60 4 times with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 76897.384
Deduct 52 from 60 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
80 divided by 13 is 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 76897.3846
The remainder is 2 after subtracting 78 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 11:
The number 13 fits into 20 1 times, leaving a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 76897.38461
Deduct 13 from 20 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 12:
The number 13 fits into 70 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 76897.384615
Subtract 65 from 70 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 13:
13 goes into 50 3 times with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 76897.3846153
Deduct 39 from 50 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 14:
13 can be fit into 110 8 times, resulting in a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 76897.38461538
If we take 104 away from 110, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

After the division, we end up with 76897.38461538 and a remainder of 6e-09.
