739944 ÷ 80 
Our goal is to divide 739944 by 80.

On to step 1:
When dividing 7 by 80, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 80

Moving on to step 2:
If we divide 73 by 80, we get 0 and a remainder of 73.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 73 and we're left with 73.
Append the next digit (9) from the dividend to 73 and continue with: 739 / 80

Step 3:
739 divided by 80 is 9 with a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 720 from 739 leaves us with 19.
Grab the next digit (9) from the dividend, add it to 19, then carry on: 199 / 80

Advancing to step 4:
80 can be fit into 199 2 times, resulting in a remainder of 39.
The number 2 becomes the next digit in our result. 
Result so far: 92.0
If we take 160 away from 199, we end up with 39.
Bring next digit (4) of the dividend behind the 39 and repeat the process: 394 / 80

Advancing to step 5:
80 goes into 394 4 times with a remainder of 74.
The number 4 becomes the next digit in our result. 
Result so far: 924.0
Deduct 320 from 394 and we're left with 74.
Include the next digit (4) from the dividend after 74, then repeat: 744 / 80

On to step 6:
If we divide 744 by 80, we get 9 and a remainder of 24.
The next digit of our result is 9. 
Result so far: 9249.0
Deduct 720 from 744 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 7:
When dividing 240 by 80, we get 3 with a remainder of 0.
The next digit of our result is 3. 
Result so far: 9249.3
Subtracting 240 from 240 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.

Going ahead to step 8:
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: 9249.3
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.

On to step 9:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 9249.3
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 9249.3 with a remainder of 0.0.
