We look at the division of 6579983 by 80 
We're looking to find how many times 80 goes into 6579983.

Advancing to step 1:
80 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 80

Moving on to step 2:
If we divide 65 by 80, we get 0 and a remainder of 65.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 65 leaves us with 65.
Grab the next digit (7) from the dividend, add it to 65, then carry on: 657 / 80

Let's proceed to step 3:
80 goes into 657 8 times with a remainder of 17.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 640 from 657, we get 17.
Fetch the next digit (9) from the dividend, attach it to 17 and continue: 179 / 80

Moving on to step 4:
80 can be fit into 179 2 times, resulting in a remainder of 19.
Put 2 as the next digit of the answer. 
Result so far: 82.0
If we subtract 160 from 179, we get 19.
Append the next digit (9) from the dividend to 19 and continue with: 199 / 80

Step 5:
80 can be fit into 199 2 times, resulting in a remainder of 39.
Record the quotient 2 as the next digit in the result. 
Result so far: 822.0
If we subtract 160 from 199, we get 39.
Include the next digit (8) from the dividend after 39, then repeat: 398 / 80

Step 6:
398 divided by 80 is 4 with a remainder of 78.
Write down 4 as next digit of the result. 
Result so far: 8224.0
If we take 320 away from 398, we end up with 78.
Include the next digit (3) from the dividend after 78, then repeat: 783 / 80

Going ahead to step 7:
783 divided by 80 is 9 with a remainder of 63.
Write down 9 as next digit of the result. 
Result so far: 82249.0
Subtracting 720 from 783 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 8:
If we divide 630 by 80, we get 7 and a remainder of 70.
Use 7 as the next digit of our solution. 
Result so far: 82249.7
If we subtract 560 from 630, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 9:
If we divide 700 by 80, we get 8 and a remainder of 60.
The next digit of our result is 8. 
Result so far: 82249.78
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.

On to step 10:
If we divide 600 by 80, we get 7 and a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 82249.787
Subtract 560 from 600 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.

Moving on to step 11:
When dividing 400 by 80, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 82249.7875
Subtract 400 from 400 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.

Going ahead to step 12:
80 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 82249.7875
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.

On to step 13:
80 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 82249.7875
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.

After the division, we end up with 82249.7875 and a remainder of 0.0.
