990654 divided by 66 
We want to figure out the number of times 990654 can be divided by 66.

Going ahead to step 1:
66 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 66

Let's proceed to step 2:
66 goes into 99 1 times with a remainder of 33.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 33 after subtracting 66 from 99.
Fetch the next digit (0) from the dividend, attach it to 33 and continue: 330 / 66

Step 3:
330 divided by 66 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 15.0
Deduct 330 from 330 and we're left with 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 66

On to step 4:
66 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 150.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 66

Advancing to step 5:
When dividing 65 by 66, we get 0 with a remainder of 65.
Use 0 as the next digit of our solution. 
Result so far: 1500.0
If we subtract 0 from 65, we get 65.
Grab the next digit (4) from the dividend, add it to 65, then carry on: 654 / 66

Moving on to step 6:
When dividing 654 by 66, we get 9 with a remainder of 60.
Record the quotient 9 as the next digit in the result. 
Result so far: 15009.0
If we subtract 594 from 654, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 7:
When dividing 600 by 66, we get 9 with a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 15009.9
If we subtract 594 from 600, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
66 goes into 60 0 times with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 15009.9
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 9:
The number 66 fits into 600 9 times, leaving a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 15009.909
Subtracting 594 from 600 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.

Advancing to step 10:
When dividing 60 by 66, we get 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 15009.909
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 11:
66 goes into 600 9 times with a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 15009.90909
Subtracting 594 from 600 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.

Advancing to step 12:
60 divided by 66 is 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 15009.90909
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 13:
66 can be fit into 600 9 times, resulting in a remainder of 6.
The next digit of our result is 9. 
Result so far: 15009.9090909
Deduct 594 from 600 and we're left 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.

On to step 14:
66 can be fit into 60 0 times, resulting in a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 15009.9090909
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Our division results in 15009.9090909 with a remaining 6e-08.
