410448 ÷ 80 
The aim is to understand the frequency of 80 in 410448.

Advancing to step 1:
If we divide 4 by 80, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 80

On to step 2:
80 can be fit into 41 0 times, resulting in a remainder of 41.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 41 to get 41.
Include the next digit (0) from the dividend after 41, then repeat: 410 / 80

Step 3:
410 divided by 80 is 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 10 after subtracting 400 from 410.
Fetch the next digit (4) from the dividend, attach it to 10 and continue: 104 / 80

Advancing to step 4:
If we divide 104 by 80, we get 1 and a remainder of 24.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
Deduct 80 from 104 and we're left with 24.
Grab the next digit (4) from the dividend, add it to 24, then carry on: 244 / 80

Advancing to step 5:
80 goes into 244 3 times with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 513.0
If we take 240 away from 244, we end up with 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 80

Advancing to step 6:
The number 80 fits into 48 0 times, leaving a remainder of 48.
Write down 0 as next digit of the result. 
Result so far: 5130.0
If we subtract 0 from 48, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 7:
The number 80 fits into 480 6 times, leaving a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 5130.6
Deduct 480 from 480 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 8:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 5130.6
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.

On to step 9:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 5130.6
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.

After the division, we end up with 5130.6 and a remainder of 0.0.
