486588 ÷ 99 
The aim is to understand the frequency of 99 in 486588.

Going ahead to step 1:
When dividing 4 by 99, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 99

Step 2:
48 divided by 99 is 0 with a remainder of 48.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 48, we end up with 48.
Fetch the next digit (6) from the dividend, attach it to 48 and continue: 486 / 99

Going ahead to step 3:
When dividing 486 by 99, we get 4 with a remainder of 90.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 396 from 486 leaves us with 90.
Bring next digit (5) of the dividend behind the 90 and repeat the process: 905 / 99

Let's proceed to step 4:
The number 99 fits into 905 9 times, leaving a remainder of 14.
The next digit of our result is 9. 
Result so far: 49.0
If we subtract 891 from 905, we get 14.
Bring next digit (8) of the dividend behind the 14 and repeat the process: 148 / 99

Moving on to step 5:
If we divide 148 by 99, we get 1 and a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 491.0
Subtract 99 from 148 to get 49.
Bring next digit (8) of the dividend behind the 49 and repeat the process: 498 / 99

Moving on to step 6:
99 can be fit into 498 5 times, resulting in a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 4915.0
The remainder is 3 after subtracting 495 from 498.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
The number 99 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 4915.0
Subtracting 0 from 30 leaves us 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.

Let's proceed to step 8:
If we divide 300 by 99, we get 3 and a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 4915.03
If we subtract 297 from 300, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 9:
99 goes into 30 0 times with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 4915.03
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 10:
99 goes into 300 3 times with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 4915.0303
Subtract 297 from 300 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 11:
99 can be fit into 30 0 times, resulting in a remainder of 30.
The next digit of our result is 0. 
Result so far: 4915.0303
Subtracting 0 from 30 leaves us 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.

Going ahead to step 12:
99 goes into 300 3 times with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 4915.030303
Subtracting 297 from 300 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 13:
The number 99 fits into 30 0 times, leaving a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 4915.030303
Subtracting 0 from 30 leaves us 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 14:
99 goes into 300 3 times with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 4915.03030303
Subtracting 297 from 300 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

In conclusion, the division gives 4915.03030303 with a balance of 3e-09.
