84870 ÷ 80 
We're looking to find how many times 80 goes into 84870.

Advancing to step 1:
If we divide 8 by 80, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 80

Advancing to step 2:
When dividing 84 by 80, we get 1 with a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 80 from 84 and we're left with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 80

Let's proceed to step 3:
When dividing 48 by 80, we get 0 with a remainder of 48.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we take 0 away from 48, we end up with 48.
Include the next digit (7) from the dividend after 48, then repeat: 487 / 80

Let's proceed to step 4:
If we divide 487 by 80, we get 6 and a remainder of 7.
Record the quotient 6 as the next digit in the result. 
Result so far: 106.0
If we take 480 away from 487, we end up with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 80

Going ahead to step 5:
80 goes into 70 0 times with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 1060.0
If we subtract 0 from 70, 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.

Going ahead to step 6:
The number 80 fits into 700 8 times, leaving a remainder of 60.
The number 8 becomes the next digit in our result. 
Result so far: 1060.8
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.

Step 7:
80 goes into 600 7 times with a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 1060.87
The remainder is 40 after subtracting 560 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 8:
The number 80 fits into 400 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 1060.875
Deduct 400 from 400 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 9:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 1060.875
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.

Moving on to step 10:
When dividing 0 by 80, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1060.875
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.

In conclusion, the division gives 1060.875 with a balance of 0.0.
