We look at the division of 87899060 by 800 
We want to divide 87899060 by 800.

Step 1:
The number 800 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 800

Going ahead to step 2:
87 divided by 800 is 0 with a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 87, we get 87.
Append the next digit (8) from the dividend to 87 and continue with: 878 / 800

Going ahead to step 3:
800 goes into 878 1 times with a remainder of 78.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 800 from 878 to get 78.
Take the next digit (9) from the dividend and append it to 78, then repeat: 789 / 800

Advancing to step 4:
800 goes into 789 0 times with a remainder of 789.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 789 and we're left with 789.
Include the next digit (9) from the dividend after 789, then repeat: 7899 / 800

Let's proceed to step 5:
When dividing 7899 by 800, we get 9 with a remainder of 699.
The number 9 becomes the next digit in our result. 
Result so far: 109.0
If we subtract 7200 from 7899, we get 699.
Include the next digit (0) from the dividend after 699, then repeat: 6990 / 800

Advancing to step 6:
The number 800 fits into 6990 8 times, leaving a remainder of 590.
Record the quotient 8 as the next digit in the result. 
Result so far: 1098.0
Deduct 6400 from 6990 and we're left with 590.
Include the next digit (6) from the dividend after 590, then repeat: 5906 / 800

Moving on to step 7:
The number 800 fits into 5906 7 times, leaving a remainder of 306.
Use 7 as the next digit of our solution. 
Result so far: 10987.0
The remainder is 306 after subtracting 5600 from 5906.
Fetch the next digit (0) from the dividend, attach it to 306 and continue: 3060 / 800

Let's proceed to step 8:
When dividing 3060 by 800, we get 3 with a remainder of 660.
Record the quotient 3 as the next digit in the result. 
Result so far: 109873.0
If we subtract 2400 from 3060, we get 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Advancing to step 9:
800 goes into 6600 8 times with a remainder of 200.
Write down 8 as next digit of the result. 
Result so far: 109873.8
Subtracting 6400 from 6600 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 10:
800 goes into 2000 2 times with a remainder of 400.
Record the quotient 2 as the next digit in the result. 
Result so far: 109873.82
Subtracting 1600 from 2000 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.

On to step 11:
4000 divided by 800 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 109873.825
Subtract 4000 from 4000 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.

Advancing to step 12:
If we divide 0 by 800, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 109873.825
If we take 0 away from 0, we end up 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.

Advancing to step 13:
When dividing 0 by 800, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 109873.825
If we take 0 away from 0, we end up 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.

The final outcome is 109873.825, with a leftover of 0.0.
