We divide 576397 by 80
The aim is to understand the frequency of 80 in 576397.

Going ahead to step 1:
80 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 80

Going ahead to step 2:
57 divided by 80 is 0 with a remainder of 57.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 57, we get 57.
Bring next digit (6) of the dividend behind the 57 and repeat the process: 576 / 80

Let's proceed to step 3:
80 goes into 576 7 times with a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 560 from 576 leaves us with 16.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 80

Going ahead to step 4:
80 can be fit into 163 2 times, resulting in a remainder of 3.
The next digit of our result is 2. 
Result so far: 72.0
If we take 160 away from 163, we end up with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 80

Going ahead to step 5:
80 can be fit into 39 0 times, resulting in a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 720.0
If we take 0 away from 39, we end up with 39.
Grab the next digit (7) from the dividend, add it to 39, then carry on: 397 / 80

Let's proceed to step 6:
When dividing 397 by 80, we get 4 with a remainder of 77.
Use 4 as the next digit of our solution. 
Result so far: 7204.0
Subtracting 320 from 397 leaves us with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Let's proceed to step 7:
When dividing 770 by 80, we get 9 with a remainder of 50.
Write down 9 as next digit of the result. 
Result so far: 7204.9
Subtracting 720 from 770 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 8:
The number 80 fits into 500 6 times, leaving a remainder of 20.
The next digit of our result is 6. 
Result so far: 7204.96
If we take 480 away from 500, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
80 goes into 200 2 times with a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 7204.962
Deduct 160 from 200 and we're left 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.

Let's proceed to step 10:
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: 7204.9625
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.

On to step 11:
If we divide 0 by 80, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 7204.9625
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.

Moving on to step 12:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 7204.9625
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.

The final outcome is 7204.9625, with a leftover of 0.0.
