We're dividing 397756 by 80 
The aim is to understand the frequency of 80 in 397756.

Moving on to step 1:
80 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 80

Let's proceed to step 2:
If we divide 39 by 80, we get 0 and a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Bring next digit (7) of the dividend behind the 39 and repeat the process: 397 / 80

On to step 3:
80 goes into 397 4 times with a remainder of 77.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 320 from 397 leaves us with 77.
Include the next digit (7) from the dividend after 77, then repeat: 777 / 80

Advancing to step 4:
The number 80 fits into 777 9 times, leaving a remainder of 57.
Write down 9 as next digit of the result. 
Result so far: 49.0
If we take 720 away from 777, we end up with 57.
Grab the next digit (5) from the dividend, add it to 57, then carry on: 575 / 80

Step 5:
If we divide 575 by 80, we get 7 and a remainder of 15.
The next digit of our result is 7. 
Result so far: 497.0
Subtracting 560 from 575 leaves us with 15.
Include the next digit (6) from the dividend after 15, then repeat: 156 / 80

Let's proceed to step 6:
80 can be fit into 156 1 times, resulting in a remainder of 76.
The next digit of our result is 1. 
Result so far: 4971.0
Subtract 80 from 156 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 7:
760 divided by 80 is 9 with a remainder of 40.
Put 9 as the next digit of the answer. 
Result so far: 4971.9
The remainder is 40 after subtracting 720 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 8:
80 can be fit into 400 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 4971.95
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.

Moving on to step 9:
0 divided by 80 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4971.95
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.

Moving on to step 10:
0 divided by 80 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4971.95
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.

Our division results in 4971.95 with a remaining 0.0.
