We're dividing 287456 by 90 
We want to divide 287456 by 90.

Advancing to step 1:
If we divide 2 by 90, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 90

On to step 2:
When dividing 28 by 90, we get 0 with a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Grab the next digit (7) from the dividend, add it to 28, then carry on: 287 / 90

Advancing to step 3:
When dividing 287 by 90, we get 3 with a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 270 from 287 to get 17.
Include the next digit (4) from the dividend after 17, then repeat: 174 / 90

Step 4:
90 goes into 174 1 times with a remainder of 84.
Write down 1 as next digit of the result. 
Result so far: 31.0
Subtracting 90 from 174 leaves us with 84.
Grab the next digit (5) from the dividend, add it to 84, then carry on: 845 / 90

Going ahead to step 5:
The number 90 fits into 845 9 times, leaving a remainder of 35.
The number 9 becomes the next digit in our result. 
Result so far: 319.0
If we subtract 810 from 845, we get 35.
Bring next digit (6) of the dividend behind the 35 and repeat the process: 356 / 90

Going ahead to step 6:
When dividing 356 by 90, we get 3 with a remainder of 86.
Use 3 as the next digit of our solution. 
Result so far: 3193.0
Subtracting 270 from 356 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 7:
When dividing 860 by 90, we get 9 with a remainder of 50.
Write down 9 as next digit of the result. 
Result so far: 3193.9
Subtract 810 from 860 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 8:
When dividing 500 by 90, we get 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 3193.95
Deduct 450 from 500 and we're left with 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 9:
90 can be fit into 500 5 times, resulting in a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 3193.955
The remainder is 50 after subtracting 450 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final result is 3193.955 with a remainder of 0.005.
