We divide 916173 by 80
We want to figure out the number of times 916173 can be divided by 80.

Advancing to step 1:
When dividing 9 by 80, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 80

On to step 2:
91 divided by 80 is 1 with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 80 from 91 leaves us with 11.
Take the next digit (6) from the dividend and append it to 11, then repeat: 116 / 80

Advancing to step 3:
80 can be fit into 116 1 times, resulting in a remainder of 36.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we take 80 away from 116, we end up with 36.
Bring next digit (1) of the dividend behind the 36 and repeat the process: 361 / 80

On to step 4:
80 can be fit into 361 4 times, resulting in a remainder of 41.
The next digit of our result is 4. 
Result so far: 114.0
Subtracting 320 from 361 leaves us with 41.
Grab the next digit (7) from the dividend, add it to 41, then carry on: 417 / 80

Let's proceed to step 5:
80 goes into 417 5 times with a remainder of 17.
Write down 5 as next digit of the result. 
Result so far: 1145.0
If we take 400 away from 417, we end up with 17.
Bring next digit (3) of the dividend behind the 17 and repeat the process: 173 / 80

Step 6:
80 can be fit into 173 2 times, resulting in a remainder of 13.
Use 2 as the next digit of our solution. 
Result so far: 11452.0
Subtract 160 from 173 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 7:
130 divided by 80 is 1 with a remainder of 50.
Put 1 as the next digit of the answer. 
Result so far: 11452.1
Deduct 80 from 130 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 8:
80 goes into 500 6 times with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 11452.16
If we subtract 480 from 500, 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.

On to step 9:
If we divide 200 by 80, we get 2 and a remainder of 40.
The next digit of our result is 2. 
Result so far: 11452.162
If we subtract 160 from 200, we 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.

On to step 10:
80 can be fit into 400 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 11452.1625
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.

On 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: 11452.1625
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.

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: 11452.1625
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.

Our division results in 11452.1625 with a remaining 0.0.
