501658 divided by 80 
We're looking to find how many times 80 goes into 501658.

Going ahead to step 1:
5 divided by 80 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 80

On to step 2:
The number 80 fits into 50 0 times, leaving a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 50, we get 50.
Fetch the next digit (1) from the dividend, attach it to 50 and continue: 501 / 80

Going ahead to step 3:
80 can be fit into 501 6 times, resulting in a remainder of 21.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 21 after subtracting 480 from 501.
Fetch the next digit (6) from the dividend, attach it to 21 and continue: 216 / 80

Step 4:
80 can be fit into 216 2 times, resulting in a remainder of 56.
Use 2 as the next digit of our solution. 
Result so far: 62.0
If we take 160 away from 216, we end up with 56.
Bring next digit (5) of the dividend behind the 56 and repeat the process: 565 / 80

Going ahead to step 5:
80 can be fit into 565 7 times, resulting in a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 627.0
Subtract 560 from 565 to get 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 80

Going ahead to step 6:
If we divide 58 by 80, we get 0 and a remainder of 58.
The number 0 becomes the next digit in our result. 
Result so far: 6270.0
Subtracting 0 from 58 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 7:
80 goes into 580 7 times with a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 6270.7
Deduct 560 from 580 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.

Moving on to step 8:
200 divided by 80 is 2 with a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 6270.72
Deduct 160 from 200 and we're left 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.

Going ahead to step 9:
400 divided by 80 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 6270.725
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.

On to step 10:
80 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 6270.725
If we subtract 0 from 0, 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.

Moving 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: 6270.725
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 outcome is 6270.725, with a leftover of 0.0.
