84039 divided by 80 
We're looking to find how many times 80 goes into 84039.

Advancing to step 1:
When dividing 8 by 80, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 80

Let's proceed to step 2:
When dividing 84 by 80, we get 1 with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 80 from 84 leaves us with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 80

Step 3:
When dividing 40 by 80, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 40, we end up with 40.
Bring next digit (3) of the dividend behind the 40 and repeat the process: 403 / 80

On to step 4:
80 goes into 403 5 times with a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 105.0
Subtract 400 from 403 to get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 80

Moving on to step 5:
39 divided by 80 is 0 with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 1050.0
Subtract 0 from 39 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 6:
The number 80 fits into 390 4 times, leaving a remainder of 70.
Record the quotient 4 as the next digit in the result. 
Result so far: 1050.4
If we subtract 320 from 390, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 7:
80 can be fit into 700 8 times, resulting in a remainder of 60.
The next digit of our result is 8. 
Result so far: 1050.48
Subtract 640 from 700 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 8:
80 can be fit into 600 7 times, resulting in a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 1050.487
Subtracting 560 from 600 leaves us 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 9:
400 divided by 80 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 1050.4875
Subtract 400 from 400 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 10:
0 divided by 80 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1050.4875
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.

Moving on to step 11:
80 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1050.4875
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 outcome is 1050.4875, with a leftover of 0.0.
