We're dividing 443548 by 80 
The aim is to understand the frequency of 80 in 443548.

Step 1:
80 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 80

Moving on to step 2:
The number 80 fits into 44 0 times, leaving a remainder of 44.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 44 after subtracting 0 from 44.
Grab the next digit (3) from the dividend, add it to 44, then carry on: 443 / 80

Step 3:
80 can be fit into 443 5 times, resulting in a remainder of 43.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 400 from 443, we get 43.
Take the next digit (5) from the dividend and append it to 43, then repeat: 435 / 80

On to step 4:
80 goes into 435 5 times with a remainder of 35.
The next digit of our result is 5. 
Result so far: 55.0
Subtracting 400 from 435 leaves us with 35.
Fetch the next digit (4) from the dividend, attach it to 35 and continue: 354 / 80

Going ahead to step 5:
The number 80 fits into 354 4 times, leaving a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 554.0
If we take 320 away from 354, we end up with 34.
Include the next digit (8) from the dividend after 34, then repeat: 348 / 80

Going ahead to step 6:
80 goes into 348 4 times with a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 5544.0
Subtracting 320 from 348 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 7:
When dividing 280 by 80, we get 3 with a remainder of 40.
Put 3 as the next digit of the answer. 
Result so far: 5544.3
Subtracting 240 from 280 leaves us 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.

Step 8:
80 can be fit into 400 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 5544.35
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.

Going ahead to step 9:
0 divided by 80 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 5544.35
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.

Moving on to step 10:
When dividing 0 by 80, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 5544.35
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.

The quotient of the division is 5544.35, and the remainder is 0.0.
