266158 divided by 80 
We want to figure out the number of times 266158 can be divided by 80.

Advancing to step 1:
80 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
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 / 80

On to step 2:
26 divided by 80 is 0 with a remainder of 26.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 26 leaves us with 26.
Fetch the next digit (6) from the dividend, attach it to 26 and continue: 266 / 80

Let's proceed to step 3:
The number 80 fits into 266 3 times, leaving a remainder of 26.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 240 away from 266, we end up with 26.
Include the next digit (1) from the dividend after 26, then repeat: 261 / 80

Advancing to step 4:
When dividing 261 by 80, we get 3 with a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 33.0
The remainder is 21 after subtracting 240 from 261.
Take the next digit (5) from the dividend and append it to 21, then repeat: 215 / 80

Moving on to step 5:
80 can be fit into 215 2 times, resulting in a remainder of 55.
Use 2 as the next digit of our solution. 
Result so far: 332.0
If we subtract 160 from 215, we get 55.
Bring next digit (8) of the dividend behind the 55 and repeat the process: 558 / 80

Advancing to step 6:
80 can be fit into 558 6 times, resulting in a remainder of 78.
Record the quotient 6 as the next digit in the result. 
Result so far: 3326.0
If we subtract 480 from 558, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 7:
80 can be fit into 780 9 times, resulting in a remainder of 60.
The number 9 becomes the next digit in our result. 
Result so far: 3326.9
Deduct 720 from 780 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.

Going ahead to step 8:
600 divided by 80 is 7 with a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 3326.97
Subtracting 560 from 600 leaves us 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.

Advancing to step 9:
80 goes into 400 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 3326.975
If we take 400 away from 400, we end up 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.

Step 10:
80 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 3326.975
If we subtract 0 from 0, we 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.

Moving on to step 11:
When dividing 0 by 80, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3326.975
If we take 0 away from 0, we end up 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 outcome is 3326.975, with a leftover of 0.0.
