We're dividing 2484 by 85 
Let's see how many times 85 fits into 2484.

Step 1:
If we divide 2 by 85, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 85

On to step 2:
The number 85 fits into 24 0 times, leaving a remainder of 24.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 24 and we're left with 24.
Grab the next digit (8) from the dividend, add it to 24, then carry on: 248 / 85

Step 3:
85 can be fit into 248 2 times, resulting in a remainder of 78.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 170 from 248 and we're left with 78.
Fetch the next digit (4) from the dividend, attach it to 78 and continue: 784 / 85

Going ahead to step 4:
85 goes into 784 9 times with a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
If we take 765 away from 784, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 5:
When dividing 190 by 85, we get 2 with a remainder of 20.
The next digit of our result is 2. 
Result so far: 29.2
Subtracting 170 from 190 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 6:
85 can be fit into 200 2 times, resulting in a remainder of 30.
Use 2 as the next digit of our solution. 
Result so far: 29.22
Subtracting 170 from 200 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.

The final result is 29.22 with a remainder of 0.03.
