We're dividing 80184870 by 660 
We're looking to find how many times 660 goes into 80184870.

Going ahead to step 1:
8 divided by 660 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 660

Going ahead to step 2:
660 goes into 80 0 times with a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Append the next digit (1) from the dividend to 80 and continue with: 801 / 660

Moving on to step 3:
If we divide 801 by 660, we get 1 and a remainder of 141.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 660 from 801 and we're left with 141.
Include the next digit (8) from the dividend after 141, then repeat: 1418 / 660

Going ahead to step 4:
If we divide 1418 by 660, we get 2 and a remainder of 98.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 1320 from 1418 to get 98.
Bring next digit (4) of the dividend behind the 98 and repeat the process: 984 / 660

Step 5:
If we divide 984 by 660, we get 1 and a remainder of 324.
Write down 1 as next digit of the result. 
Result so far: 121.0
If we take 660 away from 984, we end up with 324.
Fetch the next digit (8) from the dividend, attach it to 324 and continue: 3248 / 660

Going ahead to step 6:
660 can be fit into 3248 4 times, resulting in a remainder of 608.
Use 4 as the next digit of our solution. 
Result so far: 1214.0
Subtracting 2640 from 3248 leaves us with 608.
Fetch the next digit (7) from the dividend, attach it to 608 and continue: 6087 / 660

On to step 7:
660 goes into 6087 9 times with a remainder of 147.
Record the quotient 9 as the next digit in the result. 
Result so far: 12149.0
The remainder is 147 after subtracting 5940 from 6087.
Bring next digit (0) of the dividend behind the 147 and repeat the process: 1470 / 660

On to step 8:
660 can be fit into 1470 2 times, resulting in a remainder of 150.
The next digit of our result is 2. 
Result so far: 121492.0
If we subtract 1320 from 1470, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 9:
The number 660 fits into 1500 2 times, leaving a remainder of 180.
The next digit of our result is 2. 
Result so far: 121492.2
Deduct 1320 from 1500 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 10:
660 goes into 1800 2 times with a remainder of 480.
The number 2 becomes the next digit in our result. 
Result so far: 121492.22
If we take 1320 away from 1800, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

In conclusion, the division gives 121492.22 with a balance of 0.48.
