We divide 385880 by 99
We're looking to find how many times 99 goes into 385880.

Let's proceed to step 1:
99 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 99

Advancing to step 2:
99 goes into 38 0 times with a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 38 to get 38.
Take the next digit (5) from the dividend and append it to 38, then repeat: 385 / 99

Advancing to step 3:
The number 99 fits into 385 3 times, leaving a remainder of 88.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 297 from 385 to get 88.
Include the next digit (8) from the dividend after 88, then repeat: 888 / 99

Going ahead to step 4:
If we divide 888 by 99, we get 8 and a remainder of 96.
Write down 8 as next digit of the result. 
Result so far: 38.0
If we take 792 away from 888, we end up with 96.
Take the next digit (8) from the dividend and append it to 96, then repeat: 968 / 99

On to step 5:
99 goes into 968 9 times with a remainder of 77.
The number 9 becomes the next digit in our result. 
Result so far: 389.0
Deduct 891 from 968 and we're left with 77.
Append the next digit (0) from the dividend to 77 and continue with: 770 / 99

Going ahead to step 6:
770 divided by 99 is 7 with a remainder of 77.
The number 7 becomes the next digit in our result. 
Result so far: 3897.0
Subtracting 693 from 770 leaves us with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Moving on to step 7:
770 divided by 99 is 7 with a remainder of 77.
The number 7 becomes the next digit in our result. 
Result so far: 3897.7
Subtract 693 from 770 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Let's proceed to step 8:
99 goes into 770 7 times with a remainder of 77.
Use 7 as the next digit of our solution. 
Result so far: 3897.77
The remainder is 77 after subtracting 693 from 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

The final result is 3897.77 with a remainder of 0.077.
