We look at the division of 39414 by 80 
The aim is to understand the frequency of 80 in 39414.

Advancing to step 1:
80 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 80

Step 2:
80 goes into 39 0 times with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Append the next digit (4) from the dividend to 39 and continue with: 394 / 80

On to step 3:
80 can be fit into 394 4 times, resulting in a remainder of 74.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 320 from 394 leaves us with 74.
Fetch the next digit (1) from the dividend, attach it to 74 and continue: 741 / 80

Going ahead to step 4:
80 can be fit into 741 9 times, resulting in a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
Subtract 720 from 741 to get 21.
Bring next digit (4) of the dividend behind the 21 and repeat the process: 214 / 80

Advancing to step 5:
80 can be fit into 214 2 times, resulting in a remainder of 54.
Use 2 as the next digit of our solution. 
Result so far: 492.0
If we take 160 away from 214, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 6:
If we divide 540 by 80, we get 6 and a remainder of 60.
Put 6 as the next digit of the answer. 
Result so far: 492.6
Subtract 480 from 540 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 7:
80 can be fit into 600 7 times, resulting in a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 492.67
The remainder is 40 after subtracting 560 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 8:
80 can be fit into 400 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 492.675
Subtracting 400 from 400 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.

Advancing to step 9:
0 divided by 80 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 492.675
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.

Step 10:
If we divide 0 by 80, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 492.675
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 492.675 with a remaining 0.0.
