993489 divided by 80 
Our goal is to divide 993489 by 80.

On to step 1:
80 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 80

Moving on to step 2:
99 divided by 80 is 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 19 after subtracting 80 from 99.
Take the next digit (3) from the dividend and append it to 19, then repeat: 193 / 80

Going ahead to step 3:
If we divide 193 by 80, we get 2 and a remainder of 33.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 160 from 193 leaves us with 33.
Grab the next digit (4) from the dividend, add it to 33, then carry on: 334 / 80

On to step 4:
The number 80 fits into 334 4 times, leaving a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 124.0
Subtracting 320 from 334 leaves us with 14.
Append the next digit (8) from the dividend to 14 and continue with: 148 / 80

Step 5:
80 can be fit into 148 1 times, resulting in a remainder of 68.
The next digit of our result is 1. 
Result so far: 1241.0
Subtracting 80 from 148 leaves us with 68.
Take the next digit (9) from the dividend and append it to 68, then repeat: 689 / 80

Step 6:
The number 80 fits into 689 8 times, leaving a remainder of 49.
The number 8 becomes the next digit in our result. 
Result so far: 12418.0
The remainder is 49 after subtracting 640 from 689.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 7:
80 goes into 490 6 times with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 12418.6
If we take 480 away from 490, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
80 goes into 100 1 times with a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 12418.61
Deduct 80 from 100 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
When dividing 200 by 80, we get 2 with a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 12418.612
If we take 160 away from 200, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 10:
80 can be fit into 400 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 12418.6125
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.

Moving on to step 11:
0 divided by 80 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12418.6125
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.

Let's proceed to step 12:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 12418.6125
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 12418.6125 and a remainder of 0.0.
