Let's divide 417642 by 80
The aim is to understand the frequency of 80 in 417642.

Moving on to step 1:
80 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 80

Advancing 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
Deduct 0 from 41 and we're left with 41.
Include the next digit (7) from the dividend after 41, then repeat: 417 / 80

Step 3:
80 goes into 417 5 times with a remainder of 17.
The next digit of our result is 5. 
Result so far: 5.0
If we take 400 away from 417, we end up with 17.
Fetch the next digit (6) from the dividend, attach it to 17 and continue: 176 / 80

Let's proceed to step 4:
If we divide 176 by 80, we get 2 and a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 52.0
If we subtract 160 from 176, we get 16.
Bring next digit (4) of the dividend behind the 16 and repeat the process: 164 / 80

Going ahead to step 5:
80 can be fit into 164 2 times, resulting in a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 522.0
Deduct 160 from 164 and we're left with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 80

On to step 6:
80 can be fit into 42 0 times, resulting in a remainder of 42.
The next digit of our result is 0. 
Result so far: 5220.0
Subtract 0 from 42 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 7:
80 goes into 420 5 times with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 5220.5
If we take 400 away from 420, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
If we divide 200 by 80, we get 2 and a remainder of 40.
The next digit of our result is 2. 
Result so far: 5220.52
If we take 160 away from 200, we end up 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.

Going ahead to step 9:
When dividing 400 by 80, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 5220.525
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.

Step 10:
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: 5220.525
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.

Going ahead to step 11:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 5220.525
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.

After the division, we end up with 5220.525 and a remainder of 0.0.
