266999 ÷ 80 
We want to figure out the number of times 266999 can be divided by 80.

On to step 1:
When dividing 2 by 80, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 80

Let's proceed to step 2:
When dividing 26 by 80, we get 0 with a remainder of 26.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 26 after subtracting 0 from 26.
Bring next digit (6) of the dividend behind the 26 and repeat the process: 266 / 80

On to step 3:
The number 80 fits into 266 3 times, leaving a remainder of 26.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 240 from 266, we get 26.
Fetch the next digit (9) from the dividend, attach it to 26 and continue: 269 / 80

Going ahead to step 4:
The number 80 fits into 269 3 times, leaving a remainder of 29.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
Subtracting 240 from 269 leaves us with 29.
Append the next digit (9) from the dividend to 29 and continue with: 299 / 80

Step 5:
The number 80 fits into 299 3 times, leaving a remainder of 59.
Write down 3 as next digit of the result. 
Result so far: 333.0
If we subtract 240 from 299, we get 59.
Include the next digit (9) from the dividend after 59, then repeat: 599 / 80

Advancing to step 6:
80 can be fit into 599 7 times, resulting in a remainder of 39.
Write down 7 as next digit of the result. 
Result so far: 3337.0
Deduct 560 from 599 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 7:
80 goes into 390 4 times with a remainder of 70.
Write down 4 as next digit of the result. 
Result so far: 3337.4
The remainder is 70 after subtracting 320 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 8:
80 goes into 700 8 times with a remainder of 60.
Put 8 as the next digit of the answer. 
Result so far: 3337.48
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.

On to step 9:
The number 80 fits into 600 7 times, leaving a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 3337.487
Deduct 560 from 600 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 10:
80 goes into 400 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 3337.4875
Subtract 400 from 400 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 3337.4875
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 12:
80 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 3337.4875
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 3337.4875 with a remainder of 0.0.
