734387 ÷ 80 
We're looking to find how many times 80 goes into 734387.

Step 1:
7 divided by 80 is 0 with 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.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 80

Step 2:
If we divide 73 by 80, we get 0 and a remainder of 73.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 73 after subtracting 0 from 73.
Take the next digit (4) from the dividend and append it to 73, then repeat: 734 / 80

Advancing to step 3:
When dividing 734 by 80, we get 9 with a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 720 from 734 leaves us with 14.
Bring next digit (3) of the dividend behind the 14 and repeat the process: 143 / 80

Let's proceed to step 4:
When dividing 143 by 80, we get 1 with a remainder of 63.
The next digit of our result is 1. 
Result so far: 91.0
If we subtract 80 from 143, we get 63.
Fetch the next digit (8) from the dividend, attach it to 63 and continue: 638 / 80

Step 5:
80 can be fit into 638 7 times, resulting in a remainder of 78.
Put 7 as the next digit of the answer. 
Result so far: 917.0
Deduct 560 from 638 and we're left with 78.
Take the next digit (7) from the dividend and append it to 78, then repeat: 787 / 80

Going ahead to step 6:
787 divided by 80 is 9 with a remainder of 67.
The number 9 becomes the next digit in our result. 
Result so far: 9179.0
If we take 720 away from 787, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 7:
If we divide 670 by 80, we get 8 and a remainder of 30.
Use 8 as the next digit of our solution. 
Result so far: 9179.8
The remainder is 30 after subtracting 640 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
When dividing 300 by 80, we get 3 with a remainder of 60.
Write down 3 as next digit of the result. 
Result so far: 9179.83
If we subtract 240 from 300, we get 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:
80 goes into 600 7 times with a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 9179.837
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.

Moving on to step 10:
80 goes into 400 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 9179.8375
If we subtract 400 from 400, 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.

Let's proceed to step 11:
If we divide 0 by 80, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 9179.8375
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.

Step 12:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 9179.8375
Deduct 0 from 0 and we're left 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 9179.8375, with a leftover of 0.0.
