864498 divided by 80 
We're looking to find how many times 80 goes into 864498.

Advancing to step 1:
When dividing 8 by 80, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 80

Let's proceed to step 2:
The number 80 fits into 86 1 times, leaving a remainder of 6.
The next digit of our result is 1. 
Result so far: 1.0
If we take 80 away from 86, we end up with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 80

Let's proceed to step 3:
64 divided by 80 is 0 with a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 64 to get 64.
Grab the next digit (4) from the dividend, add it to 64, then carry on: 644 / 80

Let's proceed to step 4:
When dividing 644 by 80, we get 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 108.0
Subtracting 640 from 644 leaves us with 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 80

On to step 5:
49 divided by 80 is 0 with a remainder of 49.
Put 0 as the next digit of the answer. 
Result so far: 1080.0
If we take 0 away from 49, we end up with 49.
Bring next digit (8) of the dividend behind the 49 and repeat the process: 498 / 80

On to step 6:
When dividing 498 by 80, we get 6 with a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 10806.0
The remainder is 18 after subtracting 480 from 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 7:
80 can be fit into 180 2 times, resulting in a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 10806.2
If we take 160 away from 180, we end up 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 8:
200 divided by 80 is 2 with a remainder of 40.
The next digit of our result is 2. 
Result so far: 10806.22
Deduct 160 from 200 and we're left 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.

Our division results in 10806.22 with a remaining 0.04.
