We're dividing 266317 by 90 
Let's see how many times 90 fits into 266317.

Step 1:
The number 90 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 90

Advancing to step 2:
90 goes into 26 0 times with a remainder of 26.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 26, we end up with 26.
Take the next digit (6) from the dividend and append it to 26, then repeat: 266 / 90

Step 3:
266 divided by 90 is 2 with a remainder of 86.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 180 from 266, we get 86.
Append the next digit (3) from the dividend to 86 and continue with: 863 / 90

Step 4:
863 divided by 90 is 9 with a remainder of 53.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
Subtract 810 from 863 to get 53.
Take the next digit (1) from the dividend and append it to 53, then repeat: 531 / 90

Going ahead to step 5:
The number 90 fits into 531 5 times, leaving a remainder of 81.
Write down 5 as next digit of the result. 
Result so far: 295.0
If we take 450 away from 531, we end up with 81.
Grab the next digit (7) from the dividend, add it to 81, then carry on: 817 / 90

Advancing to step 6:
90 goes into 817 9 times with a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 2959.0
If we take 810 away from 817, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
70 divided by 90 is 0 with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 2959.0
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 8:
When dividing 700 by 90, we get 7 with a remainder of 70.
Write down 7 as next digit of the result. 
Result so far: 2959.07
If we take 630 away from 700, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 9:
90 goes into 700 7 times with a remainder of 70.
Record the quotient 7 as the next digit in the result. 
Result so far: 2959.077
Subtract 630 from 700 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final outcome is 2959.077, with a leftover of 0.007.
