We're dividing 87620864 by 660 
We want to divide 87620864 by 660.

On to step 1:
660 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 660

Going ahead to step 2:
87 divided by 660 is 0 with a remainder of 87.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 87, we get 87.
Append the next digit (6) from the dividend to 87 and continue with: 876 / 660

Step 3:
660 goes into 876 1 times with a remainder of 216.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 216 after subtracting 660 from 876.
Take the next digit (2) from the dividend and append it to 216, then repeat: 2162 / 660

On to step 4:
When dividing 2162 by 660, we get 3 with a remainder of 182.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
The remainder is 182 after subtracting 1980 from 2162.
Grab the next digit (0) from the dividend, add it to 182, then carry on: 1820 / 660

Let's proceed to step 5:
If we divide 1820 by 660, we get 2 and a remainder of 500.
The next digit of our result is 2. 
Result so far: 132.0
Subtracting 1320 from 1820 leaves us with 500.
Append the next digit (8) from the dividend to 500 and continue with: 5008 / 660

Step 6:
The number 660 fits into 5008 7 times, leaving a remainder of 388.
Record the quotient 7 as the next digit in the result. 
Result so far: 1327.0
Subtract 4620 from 5008 to get 388.
Append the next digit (6) from the dividend to 388 and continue with: 3886 / 660

Moving on to step 7:
The number 660 fits into 3886 5 times, leaving a remainder of 586.
Write down 5 as next digit of the result. 
Result so far: 13275.0
If we take 3300 away from 3886, we end up with 586.
Take the next digit (4) from the dividend and append it to 586, then repeat: 5864 / 660

Moving on to step 8:
When dividing 5864 by 660, we get 8 with a remainder of 584.
Record the quotient 8 as the next digit in the result. 
Result so far: 132758.0
Subtracting 5280 from 5864 leaves us with 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Step 9:
If we divide 5840 by 660, we get 8 and a remainder of 560.
The number 8 becomes the next digit in our result. 
Result so far: 132758.8
Subtracting 5280 from 5840 leaves us with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Let's proceed to step 10:
When dividing 5600 by 660, we get 8 with a remainder of 320.
Use 8 as the next digit of our solution. 
Result so far: 132758.88
Deduct 5280 from 5600 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

The quotient of the division is 132758.88, and the remainder is 0.32.
