We're dividing 256850 by 80 
We want to divide 256850 by 80.

On to step 1:
80 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 80

Going ahead to step 2:
80 goes into 25 0 times with a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Fetch the next digit (6) from the dividend, attach it to 25 and continue: 256 / 80

On to step 3:
256 divided by 80 is 3 with a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 240 from 256, we get 16.
Bring next digit (8) of the dividend behind the 16 and repeat the process: 168 / 80

Going ahead to step 4:
When dividing 168 by 80, we get 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 32.0
If we subtract 160 from 168, we get 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 80

Advancing to step 5:
85 divided by 80 is 1 with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 321.0
Deduct 80 from 85 and we're left with 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 80

Moving on to step 6:
When dividing 50 by 80, we get 0 with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 3210.0
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 7:
The number 80 fits into 500 6 times, leaving a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 3210.6
Deduct 480 from 500 and we're left 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.
Put 2 as the next digit of the answer. 
Result so far: 3210.62
If we subtract 160 from 200, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 9:
When dividing 400 by 80, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 3210.625
If we take 400 away from 400, 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.

Moving on to step 10:
When dividing 0 by 80, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3210.625
If we subtract 0 from 0, 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:
80 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 3210.625
If we subtract 0 from 0, 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.

The final result is 3210.625 with a remainder of 0.0.
