Step 2:
66 divided by 990 is 0 with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Grab the next digit (6) from the dividend, add it to 66, then carry on: 666 / 990

Step 3:
If we divide 666 by 990, we get 0 and a remainder of 666.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 666, we end up with 666.
Grab the next digit (4) from the dividend, add it to 666, then carry on: 6664 / 990

Going ahead to step 4:
The number 990 fits into 6664 6 times, leaving a remainder of 724.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 5940 from 6664 and we're left with 724.
Include the next digit (9) from the dividend after 724, then repeat: 7249 / 990

On to step 5:
If we divide 7249 by 990, we get 7 and a remainder of 319.
Write down 7 as next digit of the result. 
Result so far: 67.0
Deduct 6930 from 7249 and we're left with 319.
Fetch the next digit (5) from the dividend, attach it to 319 and continue: 3195 / 990

On to step 6:
990 goes into 3195 3 times with a remainder of 225.
The next digit of our result is 3. 
Result so far: 673.0
The remainder is 225 after subtracting 2970 from 3195.
Bring next digit (7) of the dividend behind the 225 and repeat the process: 2257 / 990

Step 7:
990 goes into 2257 2 times with a remainder of 277.
The next digit of our result is 2. 
Result so far: 6732.0
Deduct 1980 from 2257 and we're left with 277.
Include the next digit (6) from the dividend after 277, then repeat: 2776 / 990

Going ahead to step 8:
When dividing 2776 by 990, we get 2 with a remainder of 796.
Write down 2 as next digit of the result. 
Result so far: 67322.0
The remainder is 796 after subtracting 1980 from 2776.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7960, and continue the process.

Moving on to step 9:
7960 divided by 990 is 8 with a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 67322.8
Subtract 7920 from 7960 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
990 can be fit into 400 0 times, resulting in a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 67322.8
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 11:
The number 990 fits into 4000 4 times, leaving a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 67322.804
The remainder is 40 after subtracting 3960 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 12:
990 goes into 400 0 times with a remainder of 400.
The next digit of our result is 0. 
Result so far: 67322.804
Subtracting 0 from 400 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 13:
990 goes into 4000 4 times with a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 67322.80404
Subtract 3960 from 4000 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 14:
If we divide 400 by 990, we get 0 and a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 67322.80404
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 15:
990 can be fit into 4000 4 times, resulting in a remainder of 40.
The next digit of our result is 4. 
Result so far: 67322.8040404
Subtracting 3960 from 4000 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 16:
If we divide 400 by 990, we get 0 and a remainder of 400.
The next digit of our result is 0. 
Result so far: 67322.8040404
Deduct 0 from 400 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final outcome is 67322.8040404, with a leftover of 4e-07.
