15904296 ÷ 800 
We want to divide 15904296 by 800.

On to step 1:
800 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 800

Let's proceed to step 2:
When dividing 15 by 800, we get 0 with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Include the next digit (9) from the dividend after 15, then repeat: 159 / 800

Going ahead to step 3:
The number 800 fits into 159 0 times, leaving a remainder of 159.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 159 leaves us with 159.
Take the next digit (0) from the dividend and append it to 159, then repeat: 1590 / 800

On to step 4:
The number 800 fits into 1590 1 times, leaving a remainder of 790.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 800 from 1590, we get 790.
Append the next digit (4) from the dividend to 790 and continue with: 7904 / 800

On to step 5:
The number 800 fits into 7904 9 times, leaving a remainder of 704.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
The remainder is 704 after subtracting 7200 from 7904.
Bring next digit (2) of the dividend behind the 704 and repeat the process: 7042 / 800

Going ahead to step 6:
If we divide 7042 by 800, we get 8 and a remainder of 642.
The number 8 becomes the next digit in our result. 
Result so far: 198.0
If we take 6400 away from 7042, we end up with 642.
Append the next digit (9) from the dividend to 642 and continue with: 6429 / 800

Moving on to step 7:
When dividing 6429 by 800, we get 8 with a remainder of 29.
The next digit of our result is 8. 
Result so far: 1988.0
The remainder is 29 after subtracting 6400 from 6429.
Append the next digit (6) from the dividend to 29 and continue with: 296 / 800

Advancing to step 8:
The number 800 fits into 296 0 times, leaving a remainder of 296.
The next digit of our result is 0. 
Result so far: 19880.0
Deduct 0 from 296 and we're left with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Moving on to step 9:
The number 800 fits into 2960 3 times, leaving a remainder of 560.
The number 3 becomes the next digit in our result. 
Result so far: 19880.3
If we subtract 2400 from 2960, we get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Moving on to step 10:
5600 divided by 800 is 7 with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 19880.37
Subtract 5600 from 5600 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.

Let's proceed to step 11:
800 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 19880.37
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 12:
If we divide 0 by 800, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 19880.37
If we subtract 0 from 0, we 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.

Our division results in 19880.37 with a remaining 0.0.
