743279 ÷ 80 
We want to figure out the number of times 743279 can be divided by 80.

Let's proceed to step 1:
The number 80 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 80

Advancing to step 2:
When dividing 74 by 80, we get 0 with a remainder of 74.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 74 and we're left with 74.
Take the next digit (3) from the dividend and append it to 74, then repeat: 743 / 80

Moving on to step 3:
The number 80 fits into 743 9 times, leaving a remainder of 23.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 720 from 743 to get 23.
Append the next digit (2) from the dividend to 23 and continue with: 232 / 80

Advancing to step 4:
When dividing 232 by 80, we get 2 with a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 92.0
If we subtract 160 from 232, we get 72.
Grab the next digit (7) from the dividend, add it to 72, then carry on: 727 / 80

Step 5:
80 goes into 727 9 times with a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 929.0
The remainder is 7 after subtracting 720 from 727.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 80

Moving on to step 6:
The number 80 fits into 79 0 times, leaving a remainder of 79.
Write down 0 as next digit of the result. 
Result so far: 9290.0
Subtract 0 from 79 to get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Advancing to step 7:
The number 80 fits into 790 9 times, leaving a remainder of 70.
Use 9 as the next digit of our solution. 
Result so far: 9290.9
Deduct 720 from 790 and we're left 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.

Advancing to step 8:
80 goes into 700 8 times with a remainder of 60.
Record the quotient 8 as the next digit in the result. 
Result so far: 9290.98
If we take 640 away from 700, we end up 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.

Moving on to step 9:
If we divide 600 by 80, we get 7 and a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 9290.987
If we take 560 away from 600, we end up 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 10:
80 can be fit into 400 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 9290.9875
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.

Advancing to step 11:
If we divide 0 by 80, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 9290.9875
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 12:
When dividing 0 by 80, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 9290.9875
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.

The final outcome is 9290.9875, with a leftover of 0.0.
