266309 ÷ 75 
We want to figure out the number of times 266309 can be divided by 75.

Going ahead to step 1:
If we divide 2 by 75, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 75

Moving on to step 2:
75 can be fit into 26 0 times, resulting in a remainder of 26.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 26 and we're left with 26.
Append the next digit (6) from the dividend to 26 and continue with: 266 / 75

Moving on to step 3:
When dividing 266 by 75, we get 3 with a remainder of 41.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 225 away from 266, we end up with 41.
Append the next digit (3) from the dividend to 41 and continue with: 413 / 75

Moving on to step 4:
413 divided by 75 is 5 with a remainder of 38.
Write down 5 as next digit of the result. 
Result so far: 35.0
Subtract 375 from 413 to get 38.
Take the next digit (0) from the dividend and append it to 38, then repeat: 380 / 75

Moving on to step 5:
The number 75 fits into 380 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 355.0
Deduct 375 from 380 and we're left with 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 75

Advancing to step 6:
The number 75 fits into 59 0 times, leaving a remainder of 59.
Record the quotient 0 as the next digit in the result. 
Result so far: 3550.0
If we subtract 0 from 59, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 7:
If we divide 590 by 75, we get 7 and a remainder of 65.
The number 7 becomes the next digit in our result. 
Result so far: 3550.7
Deduct 525 from 590 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 8:
If we divide 650 by 75, we get 8 and a remainder of 50.
Record the quotient 8 as the next digit in the result. 
Result so far: 3550.78
Deduct 600 from 650 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.

Let's proceed to step 9:
The number 75 fits into 500 6 times, leaving a remainder of 50.
Put 6 as the next digit of the answer. 
Result so far: 3550.786
If we subtract 450 from 500, we 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.

On to step 10:
75 goes into 500 6 times with a remainder of 50.
Put 6 as the next digit of the answer. 
Result so far: 3550.7866
Subtract 450 from 500 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.

Our division results in 3550.7866 with a remaining 0.0005.
