487595 ÷ 99 
The aim is to understand the frequency of 99 in 487595.

Let's proceed to step 1:
4 divided by 99 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 99

Advancing to step 2:
If we divide 48 by 99, we get 0 and a remainder of 48.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 48 and we're left with 48.
Take the next digit (7) from the dividend and append it to 48, then repeat: 487 / 99

Going ahead to step 3:
The number 99 fits into 487 4 times, leaving a remainder of 91.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 396 from 487 and we're left with 91.
Append the next digit (5) from the dividend to 91 and continue with: 915 / 99

Advancing to step 4:
99 can be fit into 915 9 times, resulting in a remainder of 24.
The next digit of our result is 9. 
Result so far: 49.0
If we subtract 891 from 915, we get 24.
Fetch the next digit (9) from the dividend, attach it to 24 and continue: 249 / 99

Step 5:
If we divide 249 by 99, we get 2 and a remainder of 51.
Use 2 as the next digit of our solution. 
Result so far: 492.0
The remainder is 51 after subtracting 198 from 249.
Fetch the next digit (5) from the dividend, attach it to 51 and continue: 515 / 99

Step 6:
99 goes into 515 5 times with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 4925.0
Deduct 495 from 515 and we're left 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.

Going ahead to step 7:
When dividing 200 by 99, we get 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 4925.2
Subtracting 198 from 200 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
If we divide 20 by 99, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 4925.2
If we take 0 away from 20, 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.

Going ahead to step 9:
99 can be fit into 200 2 times, resulting in a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 4925.202
If we take 198 away from 200, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 10:
99 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 4925.202
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 11:
99 goes into 200 2 times with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 4925.20202
If we subtract 198 from 200, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 12:
99 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 4925.20202
Deduct 0 from 20 and we're left 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.

Going ahead to step 13:
If we divide 200 by 99, we get 2 and a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 4925.2020202
Subtracting 198 from 200 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 14:
20 divided by 99 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 4925.2020202
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 4925.2020202 with a remaining 2e-08.
