We divide 401169 by 80
The aim is to understand the frequency of 80 in 401169.

On to step 1:
80 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 80

Advancing to step 2:
When dividing 40 by 80, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Fetch the next digit (1) from the dividend, attach it to 40 and continue: 401 / 80

Moving on to step 3:
80 can be fit into 401 5 times, resulting in a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 400 from 401 and we're left with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 80

Going ahead to step 4:
80 can be fit into 11 0 times, resulting in a remainder of 11.
The next digit of our result is 0. 
Result so far: 50.0
If we subtract 0 from 11, we get 11.
Grab the next digit (6) from the dividend, add it to 11, then carry on: 116 / 80

Let's proceed to step 5:
When dividing 116 by 80, we get 1 with a remainder of 36.
Write down 1 as next digit of the result. 
Result so far: 501.0
Subtract 80 from 116 to get 36.
Take the next digit (9) from the dividend and append it to 36, then repeat: 369 / 80

Advancing to step 6:
The number 80 fits into 369 4 times, leaving a remainder of 49.
Use 4 as the next digit of our solution. 
Result so far: 5014.0
Deduct 320 from 369 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 7:
80 can be fit into 490 6 times, resulting in a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 5014.6
If we take 480 away from 490, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
When dividing 100 by 80, we get 1 with a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 5014.61
Subtracting 80 from 100 leaves us 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.

Moving on to step 9:
200 divided by 80 is 2 with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 5014.612
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.

On to step 10:
80 goes into 400 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 5014.6125
If we subtract 400 from 400, 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.

Moving on to step 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 5014.6125
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.

Going ahead to step 12:
If we divide 0 by 80, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 5014.6125
Deduct 0 from 0 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.

After the division, we end up with 5014.6125 and a remainder of 0.0.
