We divide 80517795 by 488
The aim is to understand the frequency of 488 in 80517795.

Step 1:
If we divide 8 by 488, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 488

Going ahead to step 2:
488 goes into 80 0 times with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Fetch the next digit (5) from the dividend, attach it to 80 and continue: 805 / 488

Moving on to step 3:
The number 488 fits into 805 1 times, leaving a remainder of 317.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 488 from 805 leaves us with 317.
Include the next digit (1) from the dividend after 317, then repeat: 3171 / 488

Advancing to step 4:
488 can be fit into 3171 6 times, resulting in a remainder of 243.
The next digit of our result is 6. 
Result so far: 16.0
If we subtract 2928 from 3171, we get 243.
Append the next digit (7) from the dividend to 243 and continue with: 2437 / 488

Advancing to step 5:
The number 488 fits into 2437 4 times, leaving a remainder of 485.
Use 4 as the next digit of our solution. 
Result so far: 164.0
Subtract 1952 from 2437 to get 485.
Grab the next digit (7) from the dividend, add it to 485, then carry on: 4857 / 488

Let's proceed to step 6:
4857 divided by 488 is 9 with a remainder of 465.
The next digit of our result is 9. 
Result so far: 1649.0
Deduct 4392 from 4857 and we're left with 465.
Bring next digit (9) of the dividend behind the 465 and repeat the process: 4659 / 488

Let's proceed to step 7:
If we divide 4659 by 488, we get 9 and a remainder of 267.
Write down 9 as next digit of the result. 
Result so far: 16499.0
If we take 4392 away from 4659, we end up with 267.
Bring next digit (5) of the dividend behind the 267 and repeat the process: 2675 / 488

Let's proceed to step 8:
If we divide 2675 by 488, we get 5 and a remainder of 235.
The next digit of our result is 5. 
Result so far: 164995.0
The remainder is 235 after subtracting 2440 from 2675.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

On to step 9:
If we divide 2350 by 488, we get 4 and a remainder of 398.
Record the quotient 4 as the next digit in the result. 
Result so far: 164995.4
Subtract 1952 from 2350 to get 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Step 10:
The number 488 fits into 3980 8 times, leaving a remainder of 76.
Put 8 as the next digit of the answer. 
Result so far: 164995.48
Subtracting 3904 from 3980 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 11:
488 can be fit into 760 1 times, resulting in a remainder of 272.
Record the quotient 1 as the next digit in the result. 
Result so far: 164995.481
Deduct 488 from 760 and we're left with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Advancing to step 12:
The number 488 fits into 2720 5 times, leaving a remainder of 280.
The number 5 becomes the next digit in our result. 
Result so far: 164995.4815
Subtracting 2440 from 2720 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 13:
The number 488 fits into 2800 5 times, leaving a remainder of 360.
Write down 5 as next digit of the result. 
Result so far: 164995.48155
Subtracting 2440 from 2800 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

The quotient of the division is 164995.48155, and the remainder is 0.00036.
