We divide 730839 by 80
We're looking to find how many times 80 goes into 730839.

Moving on to step 1:
The number 80 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 80

On to step 2:
80 can be fit into 73 0 times, resulting in a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 73 to get 73.
Grab the next digit (0) from the dividend, add it to 73, then carry on: 730 / 80

Advancing to step 3:
730 divided by 80 is 9 with a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 720 from 730 to get 10.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 80

Step 4:
If we divide 108 by 80, we get 1 and a remainder of 28.
Use 1 as the next digit of our solution. 
Result so far: 91.0
The remainder is 28 after subtracting 80 from 108.
Append the next digit (3) from the dividend to 28 and continue with: 283 / 80

On to step 5:
283 divided by 80 is 3 with a remainder of 43.
The next digit of our result is 3. 
Result so far: 913.0
Deduct 240 from 283 and we're left with 43.
Grab the next digit (9) from the dividend, add it to 43, then carry on: 439 / 80

Let's proceed to step 6:
80 can be fit into 439 5 times, resulting in a remainder of 39.
The next digit of our result is 5. 
Result so far: 9135.0
If we take 400 away from 439, we end up 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.

Let's proceed to step 7:
390 divided by 80 is 4 with a remainder of 70.
Record the quotient 4 as the next digit in the result. 
Result so far: 9135.4
If we subtract 320 from 390, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 8:
80 can be fit into 700 8 times, resulting in a remainder of 60.
Use 8 as the next digit of our solution. 
Result so far: 9135.48
The remainder is 60 after subtracting 640 from 700.
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:
80 can be fit into 600 7 times, resulting in a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 9135.487
The remainder is 40 after subtracting 560 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 10:
80 goes into 400 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 9135.4875
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.

Moving on to step 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 9135.4875
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.

Advancing to step 12:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 9135.4875
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 quotient of the division is 9135.4875, and the remainder is 0.0.
