We're dividing 90502497 by 660 
Let's see how many times 660 fits into 90502497.

Advancing to step 1:
The number 660 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 660

Advancing to step 2:
660 can be fit into 90 0 times, resulting in a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Bring next digit (5) of the dividend behind the 90 and repeat the process: 905 / 660

Advancing to step 3:
660 can be fit into 905 1 times, resulting in a remainder of 245.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 660 from 905 to get 245.
Fetch the next digit (0) from the dividend, attach it to 245 and continue: 2450 / 660

Let's proceed to step 4:
The number 660 fits into 2450 3 times, leaving a remainder of 470.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
The remainder is 470 after subtracting 1980 from 2450.
Take the next digit (2) from the dividend and append it to 470, then repeat: 4702 / 660

Let's proceed to step 5:
When dividing 4702 by 660, we get 7 with a remainder of 82.
Record the quotient 7 as the next digit in the result. 
Result so far: 137.0
Subtract 4620 from 4702 to get 82.
Include the next digit (4) from the dividend after 82, then repeat: 824 / 660

Advancing to step 6:
The number 660 fits into 824 1 times, leaving a remainder of 164.
The number 1 becomes the next digit in our result. 
Result so far: 1371.0
If we subtract 660 from 824, we get 164.
Include the next digit (9) from the dividend after 164, then repeat: 1649 / 660

Step 7:
When dividing 1649 by 660, we get 2 with a remainder of 329.
The number 2 becomes the next digit in our result. 
Result so far: 13712.0
If we subtract 1320 from 1649, we get 329.
Take the next digit (7) from the dividend and append it to 329, then repeat: 3297 / 660

Step 8:
660 goes into 3297 4 times with a remainder of 657.
Use 4 as the next digit of our solution. 
Result so far: 137124.0
The remainder is 657 after subtracting 2640 from 3297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6570, and continue the process.

Moving on to step 9:
660 can be fit into 6570 9 times, resulting in a remainder of 630.
The next digit of our result is 9. 
Result so far: 137124.9
If we take 5940 away from 6570, we end up with 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Moving on to step 10:
660 goes into 6300 9 times with a remainder of 360.
Put 9 as the next digit of the answer. 
Result so far: 137124.99
Deduct 5940 from 6300 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

The quotient of the division is 137124.99, and the remainder is 0.36.
