742209 divided by 80 
Our goal is to divide 742209 by 80.

Going ahead to step 1:
If we divide 7 by 80, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 80

Going ahead to step 2:
74 divided by 80 is 0 with a remainder of 74.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 74 leaves us with 74.
Append the next digit (2) from the dividend to 74 and continue with: 742 / 80

Step 3:
742 divided by 80 is 9 with a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 720 from 742 leaves us with 22.
Grab the next digit (2) from the dividend, add it to 22, then carry on: 222 / 80

Going ahead to step 4:
222 divided by 80 is 2 with a remainder of 62.
The next digit of our result is 2. 
Result so far: 92.0
If we subtract 160 from 222, we get 62.
Take the next digit (0) from the dividend and append it to 62, then repeat: 620 / 80

Let's proceed to step 5:
80 can be fit into 620 7 times, resulting in a remainder of 60.
The number 7 becomes the next digit in our result. 
Result so far: 927.0
Subtracting 560 from 620 leaves us with 60.
Fetch the next digit (9) from the dividend, attach it to 60 and continue: 609 / 80

Going ahead to step 6:
80 can be fit into 609 7 times, resulting in a remainder of 49.
Record the quotient 7 as the next digit in the result. 
Result so far: 9277.0
If we subtract 560 from 609, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 7:
If we divide 490 by 80, we get 6 and a remainder of 10.
The next digit of our result is 6. 
Result so far: 9277.6
If we subtract 480 from 490, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
If we divide 100 by 80, we get 1 and a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 9277.61
If we subtract 80 from 100, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
The number 80 fits into 200 2 times, leaving a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 9277.612
Subtract 160 from 200 to get 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.
The next digit of our result is 5. 
Result so far: 9277.6125
The remainder is 0 after subtracting 400 from 400.
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:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 9277.6125
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.

On to step 12:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 9277.6125
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.

The final result is 9277.6125 with a remainder of 0.0.
