489980 ÷ 66 
We want to figure out the number of times 489980 can be divided by 66.

Moving on to step 1:
If we divide 4 by 66, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 66

Advancing to step 2:
48 divided by 66 is 0 with a remainder of 48.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 48 after subtracting 0 from 48.
Append the next digit (9) from the dividend to 48 and continue with: 489 / 66

On to step 3:
When dividing 489 by 66, we get 7 with a remainder of 27.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 462 from 489 leaves us with 27.
Take the next digit (9) from the dividend and append it to 27, then repeat: 279 / 66

Moving on to step 4:
When dividing 279 by 66, we get 4 with a remainder of 15.
Put 4 as the next digit of the answer. 
Result so far: 74.0
If we subtract 264 from 279, we get 15.
Grab the next digit (8) from the dividend, add it to 15, then carry on: 158 / 66

Moving on to step 5:
If we divide 158 by 66, we get 2 and a remainder of 26.
Record the quotient 2 as the next digit in the result. 
Result so far: 742.0
The remainder is 26 after subtracting 132 from 158.
Include the next digit (0) from the dividend after 26, then repeat: 260 / 66

Let's proceed to step 6:
When dividing 260 by 66, we get 3 with a remainder of 62.
The number 3 becomes the next digit in our result. 
Result so far: 7423.0
If we take 198 away from 260, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 7:
66 goes into 620 9 times with a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 7423.9
Subtracting 594 from 620 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 8:
The number 66 fits into 260 3 times, leaving a remainder of 62.
Use 3 as the next digit of our solution. 
Result so far: 7423.93
The remainder is 62 after subtracting 198 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 9:
If we divide 620 by 66, we get 9 and a remainder of 26.
Write down 9 as next digit of the result. 
Result so far: 7423.939
Deduct 594 from 620 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 10:
The number 66 fits into 260 3 times, leaving a remainder of 62.
The number 3 becomes the next digit in our result. 
Result so far: 7423.9393
The remainder is 62 after subtracting 198 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 11:
When dividing 620 by 66, we get 9 with a remainder of 26.
Write down 9 as next digit of the result. 
Result so far: 7423.93939
The remainder is 26 after subtracting 594 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 12:
66 goes into 260 3 times with a remainder of 62.
Put 3 as the next digit of the answer. 
Result so far: 7423.939393
Deduct 198 from 260 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 13:
The number 66 fits into 620 9 times, leaving a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 7423.9393939
Subtracting 594 from 620 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 14:
66 goes into 260 3 times with a remainder of 62.
The next digit of our result is 3. 
Result so far: 7423.93939393
The remainder is 62 after subtracting 198 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

The quotient of the division is 7423.93939393, and the remainder is 6.2e-08.
