We divide 28015663 by 800
We're looking to find how many times 800 goes into 28015663.

Going ahead to step 1:
800 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 800

Going ahead to step 2:
28 divided by 800 is 0 with a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Grab the next digit (0) from the dividend, add it to 28, then carry on: 280 / 800

Going ahead to step 3:
When dividing 280 by 800, we get 0 with a remainder of 280.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 280 and we're left with 280.
Include the next digit (1) from the dividend after 280, then repeat: 2801 / 800

Moving on to step 4:
The number 800 fits into 2801 3 times, leaving a remainder of 401.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 2400 from 2801 leaves us with 401.
Bring next digit (5) of the dividend behind the 401 and repeat the process: 4015 / 800

Let's proceed to step 5:
When dividing 4015 by 800, we get 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
Deduct 4000 from 4015 and we're left with 15.
Fetch the next digit (6) from the dividend, attach it to 15 and continue: 156 / 800

Step 6:
800 goes into 156 0 times with a remainder of 156.
Use 0 as the next digit of our solution. 
Result so far: 350.0
Subtract 0 from 156 to get 156.
Fetch the next digit (6) from the dividend, attach it to 156 and continue: 1566 / 800

Step 7:
If we divide 1566 by 800, we get 1 and a remainder of 766.
Put 1 as the next digit of the answer. 
Result so far: 3501.0
Subtracting 800 from 1566 leaves us with 766.
Take the next digit (3) from the dividend and append it to 766, then repeat: 7663 / 800

Let's proceed to step 8:
When dividing 7663 by 800, we get 9 with a remainder of 463.
Record the quotient 9 as the next digit in the result. 
Result so far: 35019.0
If we take 7200 away from 7663, we end up with 463.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4630, and continue the process.

Let's proceed to step 9:
4630 divided by 800 is 5 with a remainder of 630.
Write down 5 as next digit of the result. 
Result so far: 35019.5
The remainder is 630 after subtracting 4000 from 4630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

On to step 10:
If we divide 6300 by 800, we get 7 and a remainder of 700.
Record the quotient 7 as the next digit in the result. 
Result so far: 35019.57
Subtracting 5600 from 6300 leaves us with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Let's proceed to step 11:
800 goes into 7000 8 times with a remainder of 600.
Use 8 as the next digit of our solution. 
Result so far: 35019.578
If we subtract 6400 from 7000, we get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

On to step 12:
800 can be fit into 6000 7 times, resulting in a remainder of 400.
The number 7 becomes the next digit in our result. 
Result so far: 35019.5787
If we subtract 5600 from 6000, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

On to step 13:
800 can be fit into 4000 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 35019.57875
Deduct 4000 from 4000 and we're left 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.

Going ahead to step 14:
If we divide 0 by 800, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 35019.57875
The remainder is 0 after subtracting 0 from 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 15:
The number 800 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 35019.57875
Subtract 0 from 0 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.

After the division, we end up with 35019.57875 and a remainder of 0.0.
