We divide 86758303 by 800
Our goal is to divide 86758303 by 800.

On to step 1:
When dividing 8 by 800, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 800

Let's proceed to step 2:
The number 800 fits into 86 0 times, leaving a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Take the next digit (7) from the dividend and append it to 86, then repeat: 867 / 800

On to step 3:
867 divided by 800 is 1 with a remainder of 67.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 800 from 867 and we're left with 67.
Fetch the next digit (5) from the dividend, attach it to 67 and continue: 675 / 800

Moving on to step 4:
When dividing 675 by 800, we get 0 with a remainder of 675.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 675 to get 675.
Include the next digit (8) from the dividend after 675, then repeat: 6758 / 800

Advancing to step 5:
When dividing 6758 by 800, we get 8 with a remainder of 358.
Write down 8 as next digit of the result. 
Result so far: 108.0
If we subtract 6400 from 6758, we get 358.
Take the next digit (3) from the dividend and append it to 358, then repeat: 3583 / 800

Let's proceed to step 6:
When dividing 3583 by 800, we get 4 with a remainder of 383.
Write down 4 as next digit of the result. 
Result so far: 1084.0
If we subtract 3200 from 3583, we get 383.
Include the next digit (0) from the dividend after 383, then repeat: 3830 / 800

Going ahead to step 7:
3830 divided by 800 is 4 with a remainder of 630.
Record the quotient 4 as the next digit in the result. 
Result so far: 10844.0
Deduct 3200 from 3830 and we're left with 630.
Take the next digit (3) from the dividend and append it to 630, then repeat: 6303 / 800

On to step 8:
6303 divided by 800 is 7 with a remainder of 703.
Use 7 as the next digit of our solution. 
Result so far: 108447.0
If we take 5600 away from 6303, we end up with 703.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7030, and continue the process.

Let's proceed to step 9:
800 can be fit into 7030 8 times, resulting in a remainder of 630.
The next digit of our result is 8. 
Result so far: 108447.8
If we subtract 6400 from 7030, we get 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Let's proceed to step 10:
800 goes into 6300 7 times with a remainder of 700.
The number 7 becomes the next digit in our result. 
Result so far: 108447.87
The remainder is 700 after subtracting 5600 from 6300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Moving on to step 11:
800 can be fit into 7000 8 times, resulting in a remainder of 600.
Put 8 as the next digit of the answer. 
Result so far: 108447.878
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.

Step 12:
800 can be fit into 6000 7 times, resulting in a remainder of 400.
Record the quotient 7 as the next digit in the result. 
Result so far: 108447.8787
Subtracting 5600 from 6000 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 13:
800 goes into 4000 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 108447.87875
If we subtract 4000 from 4000, 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.

On to step 14:
800 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 108447.87875
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.

Moving on to step 15:
0 divided by 800 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 108447.87875
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.

The final result is 108447.87875 with a remainder of 0.0.
