Let's divide 847899 by 80
We want to figure out the number of times 847899 can be divided by 80.

On to step 1:
The number 80 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 80

Let's proceed to step 2:
80 can be fit into 84 1 times, resulting in a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 80 from 84 and we're left with 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 80

Moving on to step 3:
80 can be fit into 47 0 times, resulting in a remainder of 47.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 47 after subtracting 0 from 47.
Include the next digit (8) from the dividend after 47, then repeat: 478 / 80

Advancing to step 4:
478 divided by 80 is 5 with a remainder of 78.
The number 5 becomes the next digit in our result. 
Result so far: 105.0
If we subtract 400 from 478, we get 78.
Bring next digit (9) of the dividend behind the 78 and repeat the process: 789 / 80

Going ahead to step 5:
80 can be fit into 789 9 times, resulting in a remainder of 69.
Write down 9 as next digit of the result. 
Result so far: 1059.0
If we subtract 720 from 789, we get 69.
Bring next digit (9) of the dividend behind the 69 and repeat the process: 699 / 80

Step 6:
699 divided by 80 is 8 with a remainder of 59.
Write down 8 as next digit of the result. 
Result so far: 10598.0
Deduct 640 from 699 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 7:
If we divide 590 by 80, we get 7 and a remainder of 30.
Put 7 as the next digit of the answer. 
Result so far: 10598.7
If we subtract 560 from 590, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
If we divide 300 by 80, we get 3 and a remainder of 60.
The next digit of our result is 3. 
Result so far: 10598.73
The remainder is 60 after subtracting 240 from 300.
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:
The number 80 fits into 600 7 times, leaving a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 10598.737
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.

Moving on to step 10:
80 goes into 400 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 10598.7375
Subtracting 400 from 400 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.

On to step 11:
0 divided by 80 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10598.7375
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.

On to step 12:
If we divide 0 by 80, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10598.7375
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.

The final result is 10598.7375 with a remainder of 0.0.
