We look at the division of 263478 by 90 
We're looking to find how many times 90 goes into 263478.

On to step 1:
90 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 take 0 away from 2, we end up with 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 90

Moving on to step 2:
90 goes into 26 0 times with a remainder of 26.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 26 leaves us with 26.
Append the next digit (3) from the dividend to 26 and continue with: 263 / 90

On to step 3:
90 goes into 263 2 times with a remainder of 83.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 180 from 263, we get 83.
Fetch the next digit (4) from the dividend, attach it to 83 and continue: 834 / 90

Going ahead to step 4:
90 can be fit into 834 9 times, resulting in a remainder of 24.
The next digit of our result is 9. 
Result so far: 29.0
The remainder is 24 after subtracting 810 from 834.
Include the next digit (7) from the dividend after 24, then repeat: 247 / 90

Step 5:
90 goes into 247 2 times with a remainder of 67.
Record the quotient 2 as the next digit in the result. 
Result so far: 292.0
Subtracting 180 from 247 leaves us with 67.
Append the next digit (8) from the dividend to 67 and continue with: 678 / 90

Advancing to step 6:
The number 90 fits into 678 7 times, leaving a remainder of 48.
Record the quotient 7 as the next digit in the result. 
Result so far: 2927.0
If we subtract 630 from 678, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 7:
If we divide 480 by 90, we get 5 and a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 2927.5
If we subtract 450 from 480, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
90 can be fit into 300 3 times, resulting in a remainder of 30.
Use 3 as the next digit of our solution. 
Result so far: 2927.53
Subtracting 270 from 300 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 9:
90 goes into 300 3 times with a remainder of 30.
Write down 3 as next digit of the result. 
Result so far: 2927.533
Subtracting 270 from 300 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The quotient of the division is 2927.533, and the remainder is 0.003.
