Let's divide 363889 by 80
The aim is to understand the frequency of 80 in 363889.

Let's proceed to step 1:
80 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 80

Advancing to step 2:
80 can be fit into 36 0 times, resulting in a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 36 to get 36.
Append the next digit (3) from the dividend to 36 and continue with: 363 / 80

On to step 3:
The number 80 fits into 363 4 times, leaving a remainder of 43.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 320 from 363 to get 43.
Grab the next digit (8) from the dividend, add it to 43, then carry on: 438 / 80

Advancing to step 4:
When dividing 438 by 80, we get 5 with a remainder of 38.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
Deduct 400 from 438 and we're left with 38.
Append the next digit (8) from the dividend to 38 and continue with: 388 / 80

Let's proceed to step 5:
When dividing 388 by 80, we get 4 with a remainder of 68.
Write down 4 as next digit of the result. 
Result so far: 454.0
Deduct 320 from 388 and we're left with 68.
Take the next digit (9) from the dividend and append it to 68, then repeat: 689 / 80

On to step 6:
80 can be fit into 689 8 times, resulting in a remainder of 49.
Write down 8 as next digit of the result. 
Result so far: 4548.0
If we subtract 640 from 689, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 7:
If we divide 490 by 80, we get 6 and a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 4548.6
The remainder is 10 after subtracting 480 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
100 divided by 80 is 1 with a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 4548.61
The remainder is 20 after subtracting 80 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
80 goes into 200 2 times with a remainder of 40.
The next digit of our result is 2. 
Result so far: 4548.612
If we take 160 away from 200, 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.

Step 10:
80 goes into 400 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 4548.6125
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.

On to step 11:
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: 4548.6125
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.

Let's proceed to step 12:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4548.6125
Subtracting 0 from 0 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.

The final result is 4548.6125 with a remainder of 0.0.
