We divide 653999 by 80
Let's see how many times 80 fits into 653999.

Step 1:
When dividing 6 by 80, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 80

Advancing to step 2:
If we divide 65 by 80, we get 0 and a remainder of 65.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 65 to get 65.
Append the next digit (3) from the dividend to 65 and continue with: 653 / 80

On to step 3:
80 can be fit into 653 8 times, resulting in a remainder of 13.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 640 from 653 and we're left with 13.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 80

Moving on to step 4:
139 divided by 80 is 1 with a remainder of 59.
Write down 1 as next digit of the result. 
Result so far: 81.0
The remainder is 59 after subtracting 80 from 139.
Bring next digit (9) of the dividend behind the 59 and repeat the process: 599 / 80

Moving on to step 5:
599 divided by 80 is 7 with a remainder of 39.
Record the quotient 7 as the next digit in the result. 
Result so far: 817.0
Subtract 560 from 599 to get 39.
Append the next digit (9) from the dividend to 39 and continue with: 399 / 80

Let's proceed to step 6:
80 goes into 399 4 times with a remainder of 79.
Use 4 as the next digit of our solution. 
Result so far: 8174.0
The remainder is 79 after subtracting 320 from 399.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Let's proceed to step 7:
790 divided by 80 is 9 with a remainder of 70.
Put 9 as the next digit of the answer. 
Result so far: 8174.9
If we take 720 away from 790, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 8:
80 goes into 700 8 times with a remainder of 60.
Use 8 as the next digit of our solution. 
Result so far: 8174.98
Deduct 640 from 700 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 9:
600 divided by 80 is 7 with a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 8174.987
If we take 560 away from 600, we end up 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.

Step 10:
The number 80 fits into 400 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 8174.9875
The remainder is 0 after subtracting 400 from 400.
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:
0 divided by 80 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 8174.9875
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.

Let's proceed to step 12:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 8174.9875
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 result is 8174.9875 with a remainder of 0.0.
