Let's divide 86877854 by 800
We want to divide 86877854 by 800.

Going ahead to step 1:
When dividing 8 by 800, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 800

On to step 2:
800 goes into 86 0 times with a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Fetch the next digit (8) from the dividend, attach it to 86 and continue: 868 / 800

Advancing to step 3:
800 goes into 868 1 times with a remainder of 68.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 800 from 868 leaves us with 68.
Grab the next digit (7) from the dividend, add it to 68, then carry on: 687 / 800

Let's proceed to step 4:
If we divide 687 by 800, we get 0 and a remainder of 687.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 687, we end up with 687.
Fetch the next digit (7) from the dividend, attach it to 687 and continue: 6877 / 800

Let's proceed to step 5:
If we divide 6877 by 800, we get 8 and a remainder of 477.
Use 8 as the next digit of our solution. 
Result so far: 108.0
The remainder is 477 after subtracting 6400 from 6877.
Take the next digit (8) from the dividend and append it to 477, then repeat: 4778 / 800

Step 6:
The number 800 fits into 4778 5 times, leaving a remainder of 778.
Record the quotient 5 as the next digit in the result. 
Result so far: 1085.0
Subtracting 4000 from 4778 leaves us with 778.
Take the next digit (5) from the dividend and append it to 778, then repeat: 7785 / 800

Step 7:
The number 800 fits into 7785 9 times, leaving a remainder of 585.
Record the quotient 9 as the next digit in the result. 
Result so far: 10859.0
Subtracting 7200 from 7785 leaves us with 585.
Include the next digit (4) from the dividend after 585, then repeat: 5854 / 800

Moving on to step 8:
The number 800 fits into 5854 7 times, leaving a remainder of 254.
The next digit of our result is 7. 
Result so far: 108597.0
If we subtract 5600 from 5854, we get 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Step 9:
When dividing 2540 by 800, we get 3 with a remainder of 140.
The next digit of our result is 3. 
Result so far: 108597.3
If we take 2400 away from 2540, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 10:
If we divide 1400 by 800, we get 1 and a remainder of 600.
Put 1 as the next digit of the answer. 
Result so far: 108597.31
If we subtract 800 from 1400, 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.

Moving on to step 11:
6000 divided by 800 is 7 with a remainder of 400.
Use 7 as the next digit of our solution. 
Result so far: 108597.317
Deduct 5600 from 6000 and we're left 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 12:
4000 divided by 800 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 108597.3175
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.

Going ahead to step 13:
800 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 108597.3175
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.

Advancing to step 14:
When dividing 0 by 800, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 108597.3175
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.

After the division, we end up with 108597.3175 and a remainder of 0.0.
