Let's divide 54961102 by 999
Our goal is to divide 54961102 by 999.

Let's proceed to step 1:
999 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 999

On to step 2:
When dividing 54 by 999, we get 0 with a remainder of 54.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 54 and we're left with 54.
Bring next digit (9) of the dividend behind the 54 and repeat the process: 549 / 999

Moving on to step 3:
999 can be fit into 549 0 times, resulting in a remainder of 549.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 549, we end up with 549.
Bring next digit (6) of the dividend behind the 549 and repeat the process: 5496 / 999

Step 4:
5496 divided by 999 is 5 with a remainder of 501.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 4995 from 5496 to get 501.
Append the next digit (1) from the dividend to 501 and continue with: 5011 / 999

Let's proceed to step 5:
When dividing 5011 by 999, we get 5 with a remainder of 16.
The number 5 becomes the next digit in our result. 
Result so far: 55.0
Subtracting 4995 from 5011 leaves us with 16.
Include the next digit (1) from the dividend after 16, then repeat: 161 / 999

Going ahead to step 6:
161 divided by 999 is 0 with a remainder of 161.
The next digit of our result is 0. 
Result so far: 550.0
Subtracting 0 from 161 leaves us with 161.
Grab the next digit (0) from the dividend, add it to 161, then carry on: 1610 / 999

Let's proceed to step 7:
When dividing 1610 by 999, we get 1 with a remainder of 611.
The next digit of our result is 1. 
Result so far: 5501.0
If we subtract 999 from 1610, we get 611.
Bring next digit (2) of the dividend behind the 611 and repeat the process: 6112 / 999

Going ahead to step 8:
6112 divided by 999 is 6 with a remainder of 118.
Write down 6 as next digit of the result. 
Result so far: 55016.0
Subtract 5994 from 6112 to get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

On to step 9:
The number 999 fits into 1180 1 times, leaving a remainder of 181.
The number 1 becomes the next digit in our result. 
Result so far: 55016.1
If we subtract 999 from 1180, we get 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Moving on to step 10:
999 goes into 1810 1 times with a remainder of 811.
Put 1 as the next digit of the answer. 
Result so far: 55016.11
Deduct 999 from 1810 and we're left with 811.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8110, and continue the process.

The quotient of the division is 55016.11, and the remainder is 0.811.
