66603184 ÷ 18 
We want to figure out the number of times 66603184 can be divided by 18.

Going ahead to step 1:
18 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 18

Going ahead to step 2:
18 goes into 66 3 times with a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 12 after subtracting 54 from 66.
Append the next digit (6) from the dividend to 12 and continue with: 126 / 18

Going ahead to step 3:
18 can be fit into 126 7 times, resulting in a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 37.0
The remainder is 0 after subtracting 126 from 126.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 18

Going ahead to step 4:
The number 18 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 370.0
The remainder is 0 after subtracting 0 from 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 18

Moving on to step 5:
18 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 3700.0
Subtract 0 from 3 to get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 18

Advancing to step 6:
18 can be fit into 31 1 times, resulting in a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 37001.0
Subtract 18 from 31 to get 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 18

On to step 7:
18 goes into 138 7 times with a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 370017.0
The remainder is 12 after subtracting 126 from 138.
Bring next digit (4) of the dividend behind the 12 and repeat the process: 124 / 18

Going ahead to step 8:
18 can be fit into 124 6 times, resulting in a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 3700176.0
Subtracting 108 from 124 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 9:
The number 18 fits into 160 8 times, leaving a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 3700176.8
Subtract 144 from 160 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 10:
If we divide 160 by 18, we get 8 and a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 3700176.88
If we subtract 144 from 160, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 3700176.88 with a remainder of 0.016.
