18978452 ÷ 499 
Let's see how many times 499 fits into 18978452.

Step 1:
499 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 499

On to step 2:
499 can be fit into 18 0 times, resulting in a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Fetch the next digit (9) from the dividend, attach it to 18 and continue: 189 / 499

Moving on to step 3:
When dividing 189 by 499, we get 0 with a remainder of 189.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 189 and we're left with 189.
Include the next digit (7) from the dividend after 189, then repeat: 1897 / 499

Let's proceed to step 4:
1897 divided by 499 is 3 with a remainder of 400.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 1497 away from 1897, we end up with 400.
Bring next digit (8) of the dividend behind the 400 and repeat the process: 4008 / 499

On to step 5:
499 can be fit into 4008 8 times, resulting in a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
If we subtract 3992 from 4008, we get 16.
Take the next digit (4) from the dividend and append it to 16, then repeat: 164 / 499

Let's proceed to step 6:
164 divided by 499 is 0 with a remainder of 164.
The next digit of our result is 0. 
Result so far: 380.0
Subtracting 0 from 164 leaves us with 164.
Fetch the next digit (5) from the dividend, attach it to 164 and continue: 1645 / 499

Going ahead to step 7:
1645 divided by 499 is 3 with a remainder of 148.
The number 3 becomes the next digit in our result. 
Result so far: 3803.0
Subtracting 1497 from 1645 leaves us with 148.
Fetch the next digit (2) from the dividend, attach it to 148 and continue: 1482 / 499

Moving on to step 8:
1482 divided by 499 is 2 with a remainder of 484.
Write down 2 as next digit of the result. 
Result so far: 38032.0
The remainder is 484 after subtracting 998 from 1482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Moving on to step 9:
499 goes into 4840 9 times with a remainder of 349.
Use 9 as the next digit of our solution. 
Result so far: 38032.9
If we take 4491 away from 4840, we end up with 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Going ahead to step 10:
499 goes into 3490 6 times with a remainder of 496.
Use 6 as the next digit of our solution. 
Result so far: 38032.96
If we subtract 2994 from 3490, we get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Going ahead to step 11:
499 goes into 4960 9 times with a remainder of 469.
Write down 9 as next digit of the result. 
Result so far: 38032.969
Subtracting 4491 from 4960 leaves us with 469.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4690, and continue the process.

Step 12:
When dividing 4690 by 499, we get 9 with a remainder of 199.
Use 9 as the next digit of our solution. 
Result so far: 38032.9699
Subtracting 4491 from 4690 leaves us with 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

After the division, we end up with 38032.9699 and a remainder of 0.00199.
