Let's divide 266311 by 80
We're looking to find how many times 80 goes into 266311.

Step 1:
80 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 80

Going ahead to step 2:
80 can be fit into 26 0 times, resulting in a remainder of 26.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 26 to get 26.
Take the next digit (6) from the dividend and append it to 26, then repeat: 266 / 80

Moving on to step 3:
When dividing 266 by 80, we get 3 with a remainder of 26.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 240 from 266 leaves us with 26.
Take the next digit (3) from the dividend and append it to 26, then repeat: 263 / 80

Advancing to step 4:
80 goes into 263 3 times with a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 33.0
If we take 240 away from 263, we end up with 23.
Grab the next digit (1) from the dividend, add it to 23, then carry on: 231 / 80

Let's proceed to step 5:
80 goes into 231 2 times with a remainder of 71.
Use 2 as the next digit of our solution. 
Result so far: 332.0
If we subtract 160 from 231, we get 71.
Append the next digit (1) from the dividend to 71 and continue with: 711 / 80

Let's proceed to step 6:
When dividing 711 by 80, we get 8 with a remainder of 71.
Record the quotient 8 as the next digit in the result. 
Result so far: 3328.0
Subtracting 640 from 711 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 7:
When dividing 710 by 80, we get 8 with a remainder of 70.
Put 8 as the next digit of the answer. 
Result so far: 3328.8
If we take 640 away from 710, 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.

Going ahead to step 8:
The number 80 fits into 700 8 times, leaving a remainder of 60.
The number 8 becomes the next digit in our result. 
Result so far: 3328.88
Deduct 640 from 700 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The quotient of the division is 3328.88, and the remainder is 0.06.
