We're dividing 492903 by 87 
Let's see how many times 87 fits into 492903.

Let's proceed to step 1:
When dividing 4 by 87, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 87

Moving on to step 2:
When dividing 49 by 87, we get 0 with a remainder of 49.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 49, we get 49.
Grab the next digit (2) from the dividend, add it to 49, then carry on: 492 / 87

Step 3:
492 divided by 87 is 5 with a remainder of 57.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 435 from 492 leaves us with 57.
Take the next digit (9) from the dividend and append it to 57, then repeat: 579 / 87

Let's proceed to step 4:
When dividing 579 by 87, we get 6 with a remainder of 57.
Use 6 as the next digit of our solution. 
Result so far: 56.0
If we take 522 away from 579, we end up with 57.
Grab the next digit (0) from the dividend, add it to 57, then carry on: 570 / 87

On to step 5:
87 goes into 570 6 times with a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 566.0
Deduct 522 from 570 and we're left with 48.
Take the next digit (3) from the dividend and append it to 48, then repeat: 483 / 87

Advancing to step 6:
If we divide 483 by 87, we get 5 and a remainder of 48.
The number 5 becomes the next digit in our result. 
Result so far: 5665.0
If we subtract 435 from 483, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 7:
87 goes into 480 5 times with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 5665.5
If we take 435 away from 480, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 8:
87 can be fit into 450 5 times, resulting in a remainder of 15.
The next digit of our result is 5. 
Result so far: 5665.55
If we subtract 435 from 450, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The quotient of the division is 5665.55, and the remainder is 0.015.
