653509 divided by 80 
Our goal is to divide 653509 by 80.

Advancing to step 1:
6 divided by 80 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 80

Advancing to step 2:
80 goes into 65 0 times with a remainder of 65.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 65 and we're left with 65.
Grab the next digit (3) from the dividend, add it to 65, then carry on: 653 / 80

Moving on to step 3:
When dividing 653 by 80, we get 8 with a remainder of 13.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 640 from 653 and we're left with 13.
Take the next digit (5) from the dividend and append it to 13, then repeat: 135 / 80

Step 4:
If we divide 135 by 80, we get 1 and a remainder of 55.
Write down 1 as next digit of the result. 
Result so far: 81.0
Subtract 80 from 135 to get 55.
Grab the next digit (0) from the dividend, add it to 55, then carry on: 550 / 80

Moving on to step 5:
If we divide 550 by 80, we get 6 and a remainder of 70.
Record the quotient 6 as the next digit in the result. 
Result so far: 816.0
Subtracting 480 from 550 leaves us with 70.
Fetch the next digit (9) from the dividend, attach it to 70 and continue: 709 / 80

Advancing to step 6:
The number 80 fits into 709 8 times, leaving a remainder of 69.
The number 8 becomes the next digit in our result. 
Result so far: 8168.0
The remainder is 69 after subtracting 640 from 709.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Moving on to step 7:
When dividing 690 by 80, we get 8 with a remainder of 50.
The next digit of our result is 8. 
Result so far: 8168.8
The remainder is 50 after subtracting 640 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 8:
80 can be fit into 500 6 times, resulting in a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 8168.86
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.

Going ahead to step 9:
80 can be fit into 200 2 times, resulting in a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 8168.862
Subtract 160 from 200 to 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.

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: 8168.8625
Deduct 400 from 400 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.

Advancing to step 11:
80 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 8168.8625
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.

Let's proceed to step 12:
0 divided by 80 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8168.8625
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.

The final outcome is 8168.8625, with a leftover of 0.0.
