Let's divide 54202988 by 999
Our goal is to divide 54202988 by 999.

Moving on 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 take 0 away from 5, we end up with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 999

Advancing to step 2:
The number 999 fits into 54 0 times, leaving a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 54 and we're left with 54.
Append the next digit (2) from the dividend to 54 and continue with: 542 / 999

Moving on to step 3:
999 goes into 542 0 times with a remainder of 542.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 542 to get 542.
Include the next digit (0) from the dividend after 542, then repeat: 5420 / 999

Advancing to step 4:
5420 divided by 999 is 5 with a remainder of 425.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 4995 from 5420 to get 425.
Fetch the next digit (2) from the dividend, attach it to 425 and continue: 4252 / 999

On to step 5:
999 can be fit into 4252 4 times, resulting in a remainder of 256.
Use 4 as the next digit of our solution. 
Result so far: 54.0
Subtracting 3996 from 4252 leaves us with 256.
Bring next digit (9) of the dividend behind the 256 and repeat the process: 2569 / 999

Step 6:
999 goes into 2569 2 times with a remainder of 571.
Record the quotient 2 as the next digit in the result. 
Result so far: 542.0
If we take 1998 away from 2569, we end up with 571.
Take the next digit (8) from the dividend and append it to 571, then repeat: 5718 / 999

Going ahead to step 7:
If we divide 5718 by 999, we get 5 and a remainder of 723.
The number 5 becomes the next digit in our result. 
Result so far: 5425.0
If we subtract 4995 from 5718, we get 723.
Take the next digit (8) from the dividend and append it to 723, then repeat: 7238 / 999

On to step 8:
If we divide 7238 by 999, we get 7 and a remainder of 245.
Use 7 as the next digit of our solution. 
Result so far: 54257.0
If we take 6993 away from 7238, we end up with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Moving on to step 9:
999 goes into 2450 2 times with a remainder of 452.
Use 2 as the next digit of our solution. 
Result so far: 54257.2
Deduct 1998 from 2450 and we're left with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

On to step 10:
999 can be fit into 4520 4 times, resulting in a remainder of 524.
The number 4 becomes the next digit in our result. 
Result so far: 54257.24
Subtract 3996 from 4520 to get 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Let's proceed to step 11:
The number 999 fits into 5240 5 times, leaving a remainder of 245.
Record the quotient 5 as the next digit in the result. 
Result so far: 54257.245
If we subtract 4995 from 5240, we get 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Let's proceed to step 12:
If we divide 2450 by 999, we get 2 and a remainder of 452.
The number 2 becomes the next digit in our result. 
Result so far: 54257.2452
Deduct 1998 from 2450 and we're left with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Advancing to step 13:
If we divide 4520 by 999, we get 4 and a remainder of 524.
Use 4 as the next digit of our solution. 
Result so far: 54257.24524
The remainder is 524 after subtracting 3996 from 4520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Moving on to step 14:
The number 999 fits into 5240 5 times, leaving a remainder of 245.
Put 5 as the next digit of the answer. 
Result so far: 54257.245245
The remainder is 245 after subtracting 4995 from 5240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Moving on to step 15:
When dividing 2450 by 999, we get 2 with a remainder of 452.
Write down 2 as next digit of the result. 
Result so far: 54257.2452452
The remainder is 452 after subtracting 1998 from 2450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Advancing to step 16:
When dividing 4520 by 999, we get 4 with a remainder of 524.
Use 4 as the next digit of our solution. 
Result so far: 54257.24524524
If we take 3996 away from 4520, we end up with 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

The final outcome is 54257.24524524, with a leftover of 5.24e-07.
