549968 ÷ 66 
We're looking to find how many times 66 goes into 549968.

Step 1:
66 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 66

Going ahead to step 2:
If we divide 54 by 66, we get 0 and a remainder of 54.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Fetch the next digit (9) from the dividend, attach it to 54 and continue: 549 / 66

Let's proceed to step 3:
When dividing 549 by 66, we get 8 with a remainder of 21.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 528 from 549 and we're left with 21.
Grab the next digit (9) from the dividend, add it to 21, then carry on: 219 / 66

On to step 4:
When dividing 219 by 66, we get 3 with a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 83.0
Deduct 198 from 219 and we're left with 21.
Include the next digit (6) from the dividend after 21, then repeat: 216 / 66

On to step 5:
The number 66 fits into 216 3 times, leaving a remainder of 18.
Record the quotient 3 as the next digit in the result. 
Result so far: 833.0
Subtracting 198 from 216 leaves us with 18.
Fetch the next digit (8) from the dividend, attach it to 18 and continue: 188 / 66

Step 6:
188 divided by 66 is 2 with a remainder of 56.
Write down 2 as next digit of the result. 
Result so far: 8332.0
Deduct 132 from 188 and we're left with 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 7:
When dividing 560 by 66, we get 8 with a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 8332.8
If we take 528 away from 560, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 8:
If we divide 320 by 66, we get 4 and a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 8332.84
Deduct 264 from 320 and we're left with 56.
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 9:
66 goes into 560 8 times with a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 8332.848
Subtract 528 from 560 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 10:
66 can be fit into 320 4 times, resulting in a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 8332.8484
Subtracting 264 from 320 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 11:
560 divided by 66 is 8 with a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 8332.84848
If we take 528 away from 560, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 12:
When dividing 320 by 66, we get 4 with a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 8332.848484
Subtract 264 from 320 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.

Advancing to step 13:
The number 66 fits into 560 8 times, leaving a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 8332.8484848
If we take 528 away from 560, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 14:
320 divided by 66 is 4 with a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 8332.84848484
Deduct 264 from 320 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The final result is 8332.84848484 with a remainder of 5.6e-08.
