86599045 ÷ 488 
The aim is to understand the frequency of 488 in 86599045.

Step 1:
If we divide 8 by 488, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 488

Moving on to step 2:
488 can be fit into 86 0 times, resulting in a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Include the next digit (5) from the dividend after 86, then repeat: 865 / 488

Step 3:
The number 488 fits into 865 1 times, leaving a remainder of 377.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 488 from 865, we get 377.
Grab the next digit (9) from the dividend, add it to 377, then carry on: 3779 / 488

On to step 4:
488 goes into 3779 7 times with a remainder of 363.
Write down 7 as next digit of the result. 
Result so far: 17.0
Deduct 3416 from 3779 and we're left with 363.
Grab the next digit (9) from the dividend, add it to 363, then carry on: 3639 / 488

Moving on to step 5:
The number 488 fits into 3639 7 times, leaving a remainder of 223.
Write down 7 as next digit of the result. 
Result so far: 177.0
Deduct 3416 from 3639 and we're left with 223.
Fetch the next digit (0) from the dividend, attach it to 223 and continue: 2230 / 488

Advancing to step 6:
2230 divided by 488 is 4 with a remainder of 278.
The number 4 becomes the next digit in our result. 
Result so far: 1774.0
If we subtract 1952 from 2230, we get 278.
Bring next digit (4) of the dividend behind the 278 and repeat the process: 2784 / 488

Going ahead to step 7:
488 can be fit into 2784 5 times, resulting in a remainder of 344.
Write down 5 as next digit of the result. 
Result so far: 17745.0
Subtract 2440 from 2784 to get 344.
Fetch the next digit (5) from the dividend, attach it to 344 and continue: 3445 / 488

Moving on to step 8:
488 can be fit into 3445 7 times, resulting in a remainder of 29.
Write down 7 as next digit of the result. 
Result so far: 177457.0
If we subtract 3416 from 3445, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 9:
The number 488 fits into 290 0 times, leaving a remainder of 290.
Put 0 as the next digit of the answer. 
Result so far: 177457.0
Subtracting 0 from 290 leaves us with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Let's proceed to step 10:
488 can be fit into 2900 5 times, resulting in a remainder of 460.
The next digit of our result is 5. 
Result so far: 177457.05
If we subtract 2440 from 2900, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Let's proceed to step 11:
488 can be fit into 4600 9 times, resulting in a remainder of 208.
The number 9 becomes the next digit in our result. 
Result so far: 177457.059
If we subtract 4392 from 4600, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Advancing to step 12:
If we divide 2080 by 488, we get 4 and a remainder of 128.
Put 4 as the next digit of the answer. 
Result so far: 177457.0594
Subtract 1952 from 2080 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 13:
488 can be fit into 1280 2 times, resulting in a remainder of 304.
Put 2 as the next digit of the answer. 
Result so far: 177457.05942
The remainder is 304 after subtracting 976 from 1280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Let's proceed to step 14:
488 can be fit into 3040 6 times, resulting in a remainder of 112.
Write down 6 as next digit of the result. 
Result so far: 177457.059426
Subtract 2928 from 3040 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 15:
The number 488 fits into 1120 2 times, leaving a remainder of 144.
Put 2 as the next digit of the answer. 
Result so far: 177457.0594262
Subtracting 976 from 1120 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 16:
The number 488 fits into 1440 2 times, leaving a remainder of 464.
Record the quotient 2 as the next digit in the result. 
Result so far: 177457.05942622
The remainder is 464 after subtracting 976 from 1440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

The final result is 177457.05942622 with a remainder of 4.64e-07.
