We divide 580627 by 80
The aim is to understand the frequency of 80 in 580627.

On to step 1:
The number 80 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 80

Let's proceed to step 2:
When dividing 58 by 80, we get 0 with a remainder of 58.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 58 after subtracting 0 from 58.
Append the next digit (0) from the dividend to 58 and continue with: 580 / 80

Moving on to step 3:
80 goes into 580 7 times with a remainder of 20.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 560 from 580, we get 20.
Include the next digit (6) from the dividend after 20, then repeat: 206 / 80

On to step 4:
206 divided by 80 is 2 with a remainder of 46.
The number 2 becomes the next digit in our result. 
Result so far: 72.0
Deduct 160 from 206 and we're left with 46.
Append the next digit (2) from the dividend to 46 and continue with: 462 / 80

On to step 5:
80 goes into 462 5 times with a remainder of 62.
Put 5 as the next digit of the answer. 
Result so far: 725.0
If we subtract 400 from 462, we get 62.
Append the next digit (7) from the dividend to 62 and continue with: 627 / 80

On to step 6:
627 divided by 80 is 7 with a remainder of 67.
Record the quotient 7 as the next digit in the result. 
Result so far: 7257.0
If we subtract 560 from 627, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 7:
If we divide 670 by 80, we get 8 and a remainder of 30.
The number 8 becomes the next digit in our result. 
Result so far: 7257.8
The remainder is 30 after subtracting 640 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
When dividing 300 by 80, we get 3 with a remainder of 60.
Write down 3 as next digit of the result. 
Result so far: 7257.83
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.

Going ahead to step 9:
If we divide 600 by 80, we get 7 and a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 7257.837
If we subtract 560 from 600, we get 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:
If we divide 400 by 80, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 7257.8375
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.

Advancing to step 11:
If we divide 0 by 80, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 7257.8375
The remainder is 0 after subtracting 0 from 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:
When dividing 0 by 80, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 7257.8375
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.

After the division, we end up with 7257.8375 and a remainder of 0.0.
