We divide 54813 by 90
Let's see how many times 90 fits into 54813.

On to step 1:
The number 90 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 90

Going ahead to step 2:
When dividing 54 by 90, we get 0 with a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Fetch the next digit (8) from the dividend, attach it to 54 and continue: 548 / 90

Let's proceed to step 3:
If we divide 548 by 90, we get 6 and a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtract 540 from 548 to get 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 90

On to step 4:
90 can be fit into 81 0 times, resulting in a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 60.0
Deduct 0 from 81 and we're left with 81.
Append the next digit (3) from the dividend to 81 and continue with: 813 / 90

Step 5:
90 can be fit into 813 9 times, resulting in a remainder of 3.
The next digit of our result is 9. 
Result so far: 609.0
If we subtract 810 from 813, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 6:
When dividing 30 by 90, we get 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 609.0
Subtract 0 from 30 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.

Going ahead to step 7:
The number 90 fits into 300 3 times, leaving a remainder of 30.
Record the quotient 3 as the next digit in the result. 
Result so far: 609.03
If we take 270 away from 300, we end up 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.

Let's proceed to step 8:
90 can be fit into 300 3 times, resulting in a remainder of 30.
Record the quotient 3 as the next digit in the result. 
Result so far: 609.033
If we take 270 away from 300, we end up 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.

After the division, we end up with 609.033 and a remainder of 0.003.
