We divide 224579 by 80
The aim is to understand the frequency of 80 in 224579.

On to step 1:
If we divide 2 by 80, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 80

Going ahead to step 2:
If we divide 22 by 80, we get 0 and a remainder of 22.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 22, we get 22.
Grab the next digit (4) from the dividend, add it to 22, then carry on: 224 / 80

Step 3:
80 can be fit into 224 2 times, resulting in a remainder of 64.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 160 from 224 leaves us with 64.
Include the next digit (5) from the dividend after 64, then repeat: 645 / 80

Step 4:
645 divided by 80 is 8 with a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 28.0
If we take 640 away from 645, we end up with 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 80

Going ahead to step 5:
When dividing 57 by 80, we get 0 with a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 280.0
Deduct 0 from 57 and we're left with 57.
Include the next digit (9) from the dividend after 57, then repeat: 579 / 80

Step 6:
80 goes into 579 7 times with a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 2807.0
If we subtract 560 from 579, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 7:
When dividing 190 by 80, we get 2 with a remainder of 30.
Put 2 as the next digit of the answer. 
Result so far: 2807.2
If we take 160 away from 190, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
The number 80 fits into 300 3 times, leaving a remainder of 60.
Put 3 as the next digit of the answer. 
Result so far: 2807.23
The remainder is 60 after subtracting 240 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
When dividing 600 by 80, we get 7 with a remainder of 40.
The next digit of our result is 7. 
Result so far: 2807.237
Subtracting 560 from 600 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 10:
400 divided by 80 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 2807.2375
Deduct 400 from 400 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 11:
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: 2807.2375
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.

Step 12:
0 divided by 80 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 2807.2375
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.

Our division results in 2807.2375 with a remaining 0.0.
