We're dividing 517525 by 80 
We want to figure out the number of times 517525 can be divided by 80.

Advancing to step 1:
80 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 80

On to step 2:
If we divide 51 by 80, we get 0 and a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Grab the next digit (7) from the dividend, add it to 51, then carry on: 517 / 80

Let's proceed to step 3:
The number 80 fits into 517 6 times, leaving a remainder of 37.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 480 away from 517, we end up with 37.
Bring next digit (5) of the dividend behind the 37 and repeat the process: 375 / 80

Going ahead to step 4:
80 goes into 375 4 times with a remainder of 55.
The number 4 becomes the next digit in our result. 
Result so far: 64.0
Deduct 320 from 375 and we're left with 55.
Bring next digit (2) of the dividend behind the 55 and repeat the process: 552 / 80

Advancing to step 5:
When dividing 552 by 80, we get 6 with a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 646.0
Subtracting 480 from 552 leaves us with 72.
Include the next digit (5) from the dividend after 72, then repeat: 725 / 80

Step 6:
The number 80 fits into 725 9 times, leaving a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 6469.0
The remainder is 5 after subtracting 720 from 725.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
50 divided by 80 is 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 6469.0
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 8:
The number 80 fits into 500 6 times, leaving a remainder of 20.
The next digit of our result is 6. 
Result so far: 6469.06
The remainder is 20 after subtracting 480 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
If we divide 200 by 80, we get 2 and a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 6469.062
If we subtract 160 from 200, 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.

Moving on to step 10:
The number 80 fits into 400 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 6469.0625
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.

On 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: 6469.0625
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.

Going ahead to step 12:
80 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 6469.0625
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.

After the division, we end up with 6469.0625 and a remainder of 0.0.
