We divide 853705 by 80
We want to divide 853705 by 80.

Going ahead to step 1:
The number 80 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 80

Going ahead to step 2:
The number 80 fits into 85 1 times, leaving a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 80 from 85, we get 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 80

Step 3:
80 goes into 53 0 times with a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 53, we end up with 53.
Take the next digit (7) from the dividend and append it to 53, then repeat: 537 / 80

Advancing to step 4:
If we divide 537 by 80, we get 6 and a remainder of 57.
Record the quotient 6 as the next digit in the result. 
Result so far: 106.0
The remainder is 57 after subtracting 480 from 537.
Grab the next digit (0) from the dividend, add it to 57, then carry on: 570 / 80

Advancing to step 5:
80 can be fit into 570 7 times, resulting in a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 1067.0
Subtract 560 from 570 to get 10.
Include the next digit (5) from the dividend after 10, then repeat: 105 / 80

Going ahead to step 6:
105 divided by 80 is 1 with a remainder of 25.
The number 1 becomes the next digit in our result. 
Result so far: 10671.0
If we take 80 away from 105, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 7:
250 divided by 80 is 3 with a remainder of 10.
The next digit of our result is 3. 
Result so far: 10671.3
Subtracting 240 from 250 leaves us 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.

Moving on to step 8:
80 goes into 100 1 times with a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 10671.31
The remainder is 20 after subtracting 80 from 100.
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.
Use 2 as the next digit of our solution. 
Result so far: 10671.312
Subtracting 160 from 200 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.

Step 10:
The number 80 fits into 400 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 10671.3125
If we subtract 400 from 400, we 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.

Let's proceed to step 11:
0 divided by 80 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10671.3125
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.

On to step 12:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10671.3125
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.

The quotient of the division is 10671.3125, and the remainder is 0.0.
