We look at the division of 3882 by 90 
Let's see how many times 90 fits into 3882.

Step 1:
If we divide 3 by 90, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 90

Step 2:
90 goes into 38 0 times with a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Fetch the next digit (8) from the dividend, attach it to 38 and continue: 388 / 90

Advancing to step 3:
90 can be fit into 388 4 times, resulting in a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 360 from 388, we get 28.
Take the next digit (2) from the dividend and append it to 28, then repeat: 282 / 90

Going ahead to step 4:
90 can be fit into 282 3 times, resulting in a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 43.0
Subtracting 270 from 282 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 5:
The number 90 fits into 120 1 times, leaving a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 43.1
Subtract 90 from 120 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 6:
300 divided by 90 is 3 with a remainder of 30.
The number 3 becomes the next digit in our result. 
Result so far: 43.13
Subtracting 270 from 300 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 7:
If we divide 300 by 90, we get 3 and a remainder of 30.
Write down 3 as next digit of the result. 
Result so far: 43.133
Subtract 270 from 300 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Our division results in 43.133 with a remaining 0.003.
