Let's divide 147909 by 99
The aim is to understand the frequency of 99 in 147909.

Moving on to step 1:
When dividing 1 by 99, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 99

On to step 2:
99 can be fit into 14 0 times, resulting in a remainder of 14.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 14 and we're left with 14.
Append the next digit (7) from the dividend to 14 and continue with: 147 / 99

Going ahead to step 3:
The number 99 fits into 147 1 times, leaving a remainder of 48.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 48 after subtracting 99 from 147.
Fetch the next digit (9) from the dividend, attach it to 48 and continue: 489 / 99

Going ahead to step 4:
The number 99 fits into 489 4 times, leaving a remainder of 93.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtract 396 from 489 to get 93.
Include the next digit (0) from the dividend after 93, then repeat: 930 / 99

On to step 5:
99 goes into 930 9 times with a remainder of 39.
Use 9 as the next digit of our solution. 
Result so far: 149.0
Subtract 891 from 930 to get 39.
Fetch the next digit (9) from the dividend, attach it to 39 and continue: 399 / 99

Let's proceed to step 6:
99 goes into 399 4 times with a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 1494.0
If we take 396 away from 399, we end up 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.

Step 7:
When dividing 30 by 99, we get 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 1494.0
The remainder is 30 after subtracting 0 from 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 8:
300 divided by 99 is 3 with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 1494.03
Deduct 297 from 300 and we're left 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.

Let's proceed to step 9:
The number 99 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 1494.03
If we take 0 away from 30, we end up 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.

Moving on to step 10:
When dividing 300 by 99, we get 3 with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 1494.0303
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.

Going ahead to step 11:
99 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 1494.0303
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.

Moving on to step 12:
The number 99 fits into 300 3 times, leaving a remainder of 3.
The next digit of our result is 3. 
Result so far: 1494.030303
If we take 297 away from 300, we end up 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:
99 can be fit into 30 0 times, resulting in a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 1494.030303
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 14:
The number 99 fits into 300 3 times, leaving a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 1494.03030303
Deduct 297 from 300 and we're left 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.

The final outcome is 1494.03030303, with a leftover of 3e-09.
