We're dividing 258857 by 80 
Let's see how many times 80 fits into 258857.

Going ahead to step 1:
80 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 80

Going ahead to step 2:
When dividing 25 by 80, we get 0 with a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Take the next digit (8) from the dividend and append it to 25, then repeat: 258 / 80

Going ahead to step 3:
258 divided by 80 is 3 with a remainder of 18.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 240 away from 258, we end up with 18.
Fetch the next digit (8) from the dividend, attach it to 18 and continue: 188 / 80

Going ahead to step 4:
80 goes into 188 2 times with a remainder of 28.
The next digit of our result is 2. 
Result so far: 32.0
If we take 160 away from 188, we end up with 28.
Fetch the next digit (5) from the dividend, attach it to 28 and continue: 285 / 80

Let's proceed to step 5:
285 divided by 80 is 3 with a remainder of 45.
Write down 3 as next digit of the result. 
Result so far: 323.0
Deduct 240 from 285 and we're left with 45.
Include the next digit (7) from the dividend after 45, then repeat: 457 / 80

Moving on to step 6:
457 divided by 80 is 5 with a remainder of 57.
Record the quotient 5 as the next digit in the result. 
Result so far: 3235.0
If we subtract 400 from 457, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 7:
The number 80 fits into 570 7 times, leaving a remainder of 10.
The next digit of our result is 7. 
Result so far: 3235.7
Subtract 560 from 570 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
100 divided by 80 is 1 with a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 3235.71
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.

On to step 9:
When dividing 200 by 80, we get 2 with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 3235.712
Subtract 160 from 200 to 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.

On to step 10:
80 can be fit into 400 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 3235.7125
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.

Let's proceed to step 11:
When dividing 0 by 80, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 3235.7125
Subtract 0 from 0 to 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 12:
If we divide 0 by 80, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3235.7125
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.

The quotient of the division is 3235.7125, and the remainder is 0.0.
