We look at the division of 518590 by 80 
We're looking to find how many times 80 goes into 518590.

Moving on to step 1:
If we divide 5 by 80, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 80

Advancing to step 2:
80 goes into 51 0 times with a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Include the next digit (8) from the dividend after 51, then repeat: 518 / 80

Going ahead to step 3:
The number 80 fits into 518 6 times, leaving a remainder of 38.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 480 away from 518, we end up with 38.
Fetch the next digit (5) from the dividend, attach it to 38 and continue: 385 / 80

Step 4:
80 goes into 385 4 times with a remainder of 65.
Write down 4 as next digit of the result. 
Result so far: 64.0
If we take 320 away from 385, we end up with 65.
Include the next digit (9) from the dividend after 65, then repeat: 659 / 80

Let's proceed to step 5:
The number 80 fits into 659 8 times, leaving a remainder of 19.
The number 8 becomes the next digit in our result. 
Result so far: 648.0
If we take 640 away from 659, we end up with 19.
Include the next digit (0) from the dividend after 19, then repeat: 190 / 80

Let's proceed to step 6:
If we divide 190 by 80, we get 2 and a remainder of 30.
Write down 2 as next digit of the result. 
Result so far: 6482.0
The remainder is 30 after subtracting 160 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 7:
300 divided by 80 is 3 with a remainder of 60.
The next digit of our result is 3. 
Result so far: 6482.3
If we take 240 away from 300, we end up 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 8:
When dividing 600 by 80, we get 7 with a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 6482.37
If we subtract 560 from 600, 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.

Step 9:
If we divide 400 by 80, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 6482.375
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.

Going ahead to step 10:
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: 6482.375
If we take 0 away from 0, we end up 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 11:
0 divided by 80 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 6482.375
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.

Our division results in 6482.375 with a remaining 0.0.
