401240 divided by 80 
The aim is to understand the frequency of 80 in 401240.

Let's proceed to step 1:
4 divided by 80 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 80

Step 2:
If we divide 40 by 80, we get 0 and a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Fetch the next digit (1) from the dividend, attach it to 40 and continue: 401 / 80

Let's proceed to step 3:
When dividing 401 by 80, we get 5 with a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we take 400 away from 401, we end up with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 80

On to step 4:
If we divide 12 by 80, we get 0 and a remainder of 12.
The next digit of our result is 0. 
Result so far: 50.0
Subtracting 0 from 12 leaves us with 12.
Bring next digit (4) of the dividend behind the 12 and repeat the process: 124 / 80

On to step 5:
124 divided by 80 is 1 with a remainder of 44.
Put 1 as the next digit of the answer. 
Result so far: 501.0
If we take 80 away from 124, we end up with 44.
Include the next digit (0) from the dividend after 44, then repeat: 440 / 80

Going ahead to step 6:
440 divided by 80 is 5 with a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 5015.0
If we take 400 away from 440, 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.

Moving on to step 7:
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: 5015.5
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.

Going ahead to step 8:
0 divided by 80 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 5015.5
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.

Moving 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: 5015.5
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.

Our division results in 5015.5 with a remaining 0.0.
