Let's divide 16528820 by 660
Our goal is to divide 16528820 by 660.

Step 1:
The number 660 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 660

Step 2:
16 divided by 660 is 0 with a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Take the next digit (5) from the dividend and append it to 16, then repeat: 165 / 660

Step 3:
660 can be fit into 165 0 times, resulting in a remainder of 165.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 165 leaves us with 165.
Fetch the next digit (2) from the dividend, attach it to 165 and continue: 1652 / 660

Moving on to step 4:
1652 divided by 660 is 2 with a remainder of 332.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 1320 away from 1652, we end up with 332.
Append the next digit (8) from the dividend to 332 and continue with: 3328 / 660

On to step 5:
If we divide 3328 by 660, we get 5 and a remainder of 28.
Write down 5 as next digit of the result. 
Result so far: 25.0
Deduct 3300 from 3328 and we're left with 28.
Fetch the next digit (8) from the dividend, attach it to 28 and continue: 288 / 660

On to step 6:
If we divide 288 by 660, we get 0 and a remainder of 288.
Write down 0 as next digit of the result. 
Result so far: 250.0
Subtract 0 from 288 to get 288.
Grab the next digit (2) from the dividend, add it to 288, then carry on: 2882 / 660

Advancing to step 7:
660 goes into 2882 4 times with a remainder of 242.
Record the quotient 4 as the next digit in the result. 
Result so far: 2504.0
Deduct 2640 from 2882 and we're left with 242.
Include the next digit (0) from the dividend after 242, then repeat: 2420 / 660

Going ahead to step 8:
660 goes into 2420 3 times with a remainder of 440.
Put 3 as the next digit of the answer. 
Result so far: 25043.0
Subtract 1980 from 2420 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Let's proceed to step 9:
The number 660 fits into 4400 6 times, leaving a remainder of 440.
The number 6 becomes the next digit in our result. 
Result so far: 25043.6
If we subtract 3960 from 4400, we get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Moving on to step 10:
4400 divided by 660 is 6 with a remainder of 440.
Record the quotient 6 as the next digit in the result. 
Result so far: 25043.66
If we take 3960 away from 4400, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

The final outcome is 25043.66, with a leftover of 0.44.
