We're dividing 802387 by 80 
Let's see how many times 80 fits into 802387.

Moving on to step 1:
8 divided by 80 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 80

On to step 2:
80 divided by 80 is 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 80 from 80 leaves us with 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 80

Moving on to step 3:
If we divide 2 by 80, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 80

Going ahead to step 4:
80 can be fit into 23 0 times, resulting in a remainder of 23.
The next digit of our result is 0. 
Result so far: 100.0
If we take 0 away from 23, we end up with 23.
Include the next digit (8) from the dividend after 23, then repeat: 238 / 80

Advancing to step 5:
80 can be fit into 238 2 times, resulting in a remainder of 78.
Put 2 as the next digit of the answer. 
Result so far: 1002.0
Subtracting 160 from 238 leaves us with 78.
Include the next digit (7) from the dividend after 78, then repeat: 787 / 80

Step 6:
When dividing 787 by 80, we get 9 with a remainder of 67.
Record the quotient 9 as the next digit in the result. 
Result so far: 10029.0
If we take 720 away from 787, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 7:
670 divided by 80 is 8 with a remainder of 30.
Write down 8 as next digit of the result. 
Result so far: 10029.8
Deduct 640 from 670 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
The number 80 fits into 300 3 times, leaving a remainder of 60.
The next digit of our result is 3. 
Result so far: 10029.83
If we take 240 away from 300, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 9:
If we divide 600 by 80, we get 7 and a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 10029.837
If we subtract 560 from 600, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
When dividing 400 by 80, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 10029.8375
If we subtract 400 from 400, 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.

Moving on to step 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 10029.8375
Deduct 0 from 0 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.

Step 12:
If we divide 0 by 80, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10029.8375
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.

After the division, we end up with 10029.8375 and a remainder of 0.0.
