We look at the division of 491593 by 80 
We're looking to find how many times 80 goes into 491593.

Step 1:
When dividing 4 by 80, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 80

Going ahead to step 2:
When dividing 49 by 80, we get 0 with a remainder of 49.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 49 and we're left with 49.
Include the next digit (1) from the dividend after 49, then repeat: 491 / 80

On to step 3:
If we divide 491 by 80, we get 6 and a remainder of 11.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 480 from 491 to get 11.
Bring next digit (5) of the dividend behind the 11 and repeat the process: 115 / 80

Let's proceed to step 4:
80 goes into 115 1 times with a remainder of 35.
Write down 1 as next digit of the result. 
Result so far: 61.0
Subtract 80 from 115 to get 35.
Append the next digit (9) from the dividend to 35 and continue with: 359 / 80

On to step 5:
The number 80 fits into 359 4 times, leaving a remainder of 39.
The next digit of our result is 4. 
Result so far: 614.0
Subtracting 320 from 359 leaves us with 39.
Bring next digit (3) of the dividend behind the 39 and repeat the process: 393 / 80

Going ahead to step 6:
If we divide 393 by 80, we get 4 and a remainder of 73.
Record the quotient 4 as the next digit in the result. 
Result so far: 6144.0
If we take 320 away from 393, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 7:
80 goes into 730 9 times with a remainder of 10.
The next digit of our result is 9. 
Result so far: 6144.9
If we subtract 720 from 730, 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.

Going ahead to step 8:
80 can be fit into 100 1 times, resulting in a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 6144.91
Deduct 80 from 100 and we're left with 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:
80 goes into 200 2 times with a remainder of 40.
The next digit of our result is 2. 
Result so far: 6144.912
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.

Moving on 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: 6144.9125
Subtracting 400 from 400 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.

On to step 11:
If we divide 0 by 80, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 6144.9125
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.

On to step 12:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 6144.9125
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.

After the division, we end up with 6144.9125 and a remainder of 0.0.
