Going ahead to step 3:
The number 285 fits into 580 2 times, leaving a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 10 after subtracting 570 from 580.
Include the next digit (7) from the dividend after 10, then repeat: 107 / 285

Advancing to step 4:
When dividing 107 by 285, we get 0 with a remainder of 107.
The next digit of our result is 0. 
Result so far: 20.0
If we subtract 0 from 107, we get 107.
Append the next digit (8) from the dividend to 107 and continue with: 1078 / 285

Advancing to step 5:
1078 divided by 285 is 3 with a remainder of 223.
The next digit of our result is 3. 
Result so far: 203.0
The remainder is 223 after subtracting 855 from 1078.
Include the next digit (3) from the dividend after 223, then repeat: 2233 / 285

Advancing to step 6:
If we divide 2233 by 285, we get 7 and a remainder of 238.
The next digit of our result is 7. 
Result so far: 2037.0
The remainder is 238 after subtracting 1995 from 2233.
Bring next digit (7) of the dividend behind the 238 and repeat the process: 2387 / 285

Let's proceed to step 7:
285 can be fit into 2387 8 times, resulting in a remainder of 107.
The number 8 becomes the next digit in our result. 
Result so far: 20378.0
If we subtract 2280 from 2387, we get 107.
Take the next digit (1) from the dividend and append it to 107, then repeat: 1071 / 285

Let's proceed to step 8:
When dividing 1071 by 285, we get 3 with a remainder of 216.
Record the quotient 3 as the next digit in the result. 
Result so far: 203783.0
Deduct 855 from 1071 and we're left with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

On to step 9:
The number 285 fits into 2160 7 times, leaving a remainder of 165.
Put 7 as the next digit of the answer. 
Result so far: 203783.7
Subtracting 1995 from 2160 leaves us with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

On to step 10:
When dividing 1650 by 285, we get 5 with a remainder of 225.
Record the quotient 5 as the next digit in the result. 
Result so far: 203783.75
Subtracting 1425 from 1650 leaves us with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

On to step 11:
The number 285 fits into 2250 7 times, leaving a remainder of 255.
Write down 7 as next digit of the result. 
Result so far: 203783.757
Subtracting 1995 from 2250 leaves us with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Moving on to step 12:
If we divide 2550 by 285, we get 8 and a remainder of 270.
Record the quotient 8 as the next digit in the result. 
Result so far: 203783.7578
If we subtract 2280 from 2550, we get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Let's proceed to step 13:
When dividing 2700 by 285, we get 9 with a remainder of 135.
Record the quotient 9 as the next digit in the result. 
Result so far: 203783.75789
The remainder is 135 after subtracting 2565 from 2700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Let's proceed to step 14:
The number 285 fits into 1350 4 times, leaving a remainder of 210.
Use 4 as the next digit of our solution. 
Result so far: 203783.757894
Deduct 1140 from 1350 and we're left with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

On to step 15:
2100 divided by 285 is 7 with a remainder of 105.
The number 7 becomes the next digit in our result. 
Result so far: 203783.7578947
Subtract 1995 from 2100 to get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Let's proceed to step 16:
When dividing 1050 by 285, we get 3 with a remainder of 195.
The number 3 becomes the next digit in our result. 
Result so far: 203783.75789473
If we subtract 855 from 1050, we get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Our division results in 203783.75789473 with a remaining 1.95e-07.
