853678 divided by 80 
We want to divide 853678 by 80.

Let's proceed to step 1:
8 divided by 80 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 80

Advancing to step 2:
When dividing 85 by 80, we get 1 with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 80 from 85 and we're left with 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 80

Going ahead to step 3:
When dividing 53 by 80, we get 0 with a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 53 after subtracting 0 from 53.
Append the next digit (6) from the dividend to 53 and continue with: 536 / 80

Advancing to step 4:
80 can be fit into 536 6 times, resulting in a remainder of 56.
Put 6 as the next digit of the answer. 
Result so far: 106.0
If we take 480 away from 536, we end up with 56.
Take the next digit (7) from the dividend and append it to 56, then repeat: 567 / 80

Step 5:
The number 80 fits into 567 7 times, leaving a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 1067.0
Deduct 560 from 567 and we're left with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 80

Moving on to step 6:
80 can be fit into 78 0 times, resulting in a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 10670.0
Subtracting 0 from 78 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 7:
780 divided by 80 is 9 with a remainder of 60.
Put 9 as the next digit of the answer. 
Result so far: 10670.9
If we take 720 away from 780, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 8:
If we divide 600 by 80, we get 7 and a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 10670.97
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 9:
400 divided by 80 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 10670.975
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.

Advancing to step 10:
0 divided by 80 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10670.975
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.

Step 11:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10670.975
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.

In conclusion, the division gives 10670.975 with a balance of 0.0.
