14478021 ÷ 798 
Our goal is to divide 14478021 by 798.

Let's proceed to step 1:
The number 798 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 798

Step 2:
798 goes into 14 0 times with a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 14 after subtracting 0 from 14.
Fetch the next digit (4) from the dividend, attach it to 14 and continue: 144 / 798

Let's proceed to step 3:
798 goes into 144 0 times with a remainder of 144.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 144, we get 144.
Include the next digit (7) from the dividend after 144, then repeat: 1447 / 798

Advancing to step 4:
798 goes into 1447 1 times with a remainder of 649.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 798 from 1447 leaves us with 649.
Bring next digit (8) of the dividend behind the 649 and repeat the process: 6498 / 798

Advancing to step 5:
If we divide 6498 by 798, we get 8 and a remainder of 114.
The next digit of our result is 8. 
Result so far: 18.0
If we take 6384 away from 6498, we end up with 114.
Take the next digit (0) from the dividend and append it to 114, then repeat: 1140 / 798

Going ahead to step 6:
The number 798 fits into 1140 1 times, leaving a remainder of 342.
Put 1 as the next digit of the answer. 
Result so far: 181.0
If we subtract 798 from 1140, we get 342.
Include the next digit (2) from the dividend after 342, then repeat: 3422 / 798

Step 7:
If we divide 3422 by 798, we get 4 and a remainder of 230.
Record the quotient 4 as the next digit in the result. 
Result so far: 1814.0
The remainder is 230 after subtracting 3192 from 3422.
Append the next digit (1) from the dividend to 230 and continue with: 2301 / 798

On to step 8:
The number 798 fits into 2301 2 times, leaving a remainder of 705.
The number 2 becomes the next digit in our result. 
Result so far: 18142.0
If we take 1596 away from 2301, we end up with 705.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7050, and continue the process.

On to step 9:
798 can be fit into 7050 8 times, resulting in a remainder of 666.
Use 8 as the next digit of our solution. 
Result so far: 18142.8
Subtract 6384 from 7050 to get 666.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6660, and continue the process.

Step 10:
6660 divided by 798 is 8 with a remainder of 276.
Use 8 as the next digit of our solution. 
Result so far: 18142.88
Subtracting 6384 from 6660 leaves us with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

The final result is 18142.88 with a remainder of 0.276.
