Let's divide 899855 by 80
We're looking to find how many times 80 goes into 899855.

Let's proceed to step 1:
80 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 80

On to step 2:
80 can be fit into 89 1 times, resulting in a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 80 from 89 and we're left with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 80

Moving on to step 3:
If we divide 99 by 80, we get 1 and a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we subtract 80 from 99, we get 19.
Grab the next digit (8) from the dividend, add it to 19, then carry on: 198 / 80

Going ahead to step 4:
The number 80 fits into 198 2 times, leaving a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 112.0
If we subtract 160 from 198, we get 38.
Include the next digit (5) from the dividend after 38, then repeat: 385 / 80

On to step 5:
80 goes into 385 4 times with a remainder of 65.
Put 4 as the next digit of the answer. 
Result so far: 1124.0
Subtract 320 from 385 to get 65.
Fetch the next digit (5) from the dividend, attach it to 65 and continue: 655 / 80

Going ahead to step 6:
655 divided by 80 is 8 with a remainder of 15.
Record the quotient 8 as the next digit in the result. 
Result so far: 11248.0
Subtracting 640 from 655 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 7:
80 goes into 150 1 times with a remainder of 70.
The number 1 becomes the next digit in our result. 
Result so far: 11248.1
Subtract 80 from 150 to 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.

On to step 8:
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: 11248.18
If we take 640 away from 700, 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.

Step 9:
When dividing 600 by 80, we get 7 with a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 11248.187
Deduct 560 from 600 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.

On to step 10:
The number 80 fits into 400 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 11248.1875
The remainder is 0 after subtracting 400 from 400.
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: 11248.1875
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 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 11248.1875
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.

The final result is 11248.1875 with a remainder of 0.0.
