We divide 543099 by 66
We're looking to find how many times 66 goes into 543099.

Let's proceed to 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.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 66

Advancing to step 2:
66 goes into 54 0 times with a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Include the next digit (3) from the dividend after 54, then repeat: 543 / 66

Moving on to step 3:
When dividing 543 by 66, we get 8 with a remainder of 15.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 15 after subtracting 528 from 543.
Include the next digit (0) from the dividend after 15, then repeat: 150 / 66

On to step 4:
When dividing 150 by 66, we get 2 with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 82.0
If we subtract 132 from 150, we get 18.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 66

Step 5:
When dividing 189 by 66, we get 2 with a remainder of 57.
Put 2 as the next digit of the answer. 
Result so far: 822.0
If we subtract 132 from 189, we get 57.
Grab the next digit (9) from the dividend, add it to 57, then carry on: 579 / 66

Let's proceed to step 6:
The number 66 fits into 579 8 times, leaving a remainder of 51.
The next digit of our result is 8. 
Result so far: 8228.0
Deduct 528 from 579 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 7:
66 goes into 510 7 times with a remainder of 48.
Use 7 as the next digit of our solution. 
Result so far: 8228.7
If we take 462 away from 510, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 8:
If we divide 480 by 66, we get 7 and a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 8228.77
Subtract 462 from 480 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Our division results in 8228.77 with a remaining 0.018.
