Let's divide 54900999 by 900
We want to divide 54900999 by 900.

Going ahead to step 1:
900 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 900

On to step 2:
900 goes into 54 0 times with a remainder of 54.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 54 after subtracting 0 from 54.
Fetch the next digit (9) from the dividend, attach it to 54 and continue: 549 / 900

Going ahead to step 3:
900 can be fit into 549 0 times, resulting in a remainder of 549.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 549 and we're left with 549.
Include the next digit (0) from the dividend after 549, then repeat: 5490 / 900

Advancing to step 4:
If we divide 5490 by 900, we get 6 and a remainder of 90.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 5400 from 5490 and we're left with 90.
Include the next digit (0) from the dividend after 90, then repeat: 900 / 900

Let's proceed to step 5:
900 can be fit into 900 1 times, resulting in a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 61.0
If we subtract 900 from 900, we get 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 900

Advancing to step 6:
If we divide 9 by 900, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 610.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 900

Step 7:
When dividing 99 by 900, we get 0 with a remainder of 99.
Put 0 as the next digit of the answer. 
Result so far: 6100.0
Deduct 0 from 99 and we're left with 99.
Bring next digit (9) of the dividend behind the 99 and repeat the process: 999 / 900

Step 8:
900 goes into 999 1 times with a remainder of 99.
Put 1 as the next digit of the answer. 
Result so far: 61001.0
If we subtract 900 from 999, we get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Step 9:
The number 900 fits into 990 1 times, leaving a remainder of 90.
The number 1 becomes the next digit in our result. 
Result so far: 61001.1
Subtract 900 from 990 to get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 10:
When dividing 900 by 900, we get 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 61001.11
Subtract 900 from 900 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 61001.11, and the remainder is 0.0.
