508030 divided by 80 
The aim is to understand the frequency of 80 in 508030.

Advancing to step 1:
When dividing 5 by 80, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 80

On to step 2:
When dividing 50 by 80, we get 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 50 and we're left with 50.
Take the next digit (8) from the dividend and append it to 50, then repeat: 508 / 80

Step 3:
If we divide 508 by 80, we get 6 and a remainder of 28.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 480 from 508 to get 28.
Fetch the next digit (0) from the dividend, attach it to 28 and continue: 280 / 80

Step 4:
If we divide 280 by 80, we get 3 and a remainder of 40.
Record the quotient 3 as the next digit in the result. 
Result so far: 63.0
If we take 240 away from 280, we end up with 40.
Grab the next digit (3) from the dividend, add it to 40, then carry on: 403 / 80

On to step 5:
The number 80 fits into 403 5 times, leaving a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 635.0
If we take 400 away from 403, we end up with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 80

Going ahead to step 6:
80 goes into 30 0 times with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 6350.0
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 7:
The number 80 fits into 300 3 times, leaving a remainder of 60.
Use 3 as the next digit of our solution. 
Result so far: 6350.3
Subtracting 240 from 300 leaves us 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.
The next digit of our result is 7. 
Result so far: 6350.37
Deduct 560 from 600 and we're left 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.

On to step 9:
When dividing 400 by 80, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 6350.375
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.

Moving on to step 10:
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: 6350.375
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.

Advancing to step 11:
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: 6350.375
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.

The final result is 6350.375 with a remainder of 0.0.
