145828 divided by 99 
The aim is to understand the frequency of 99 in 145828.

Advancing to step 1:
99 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 99

Step 2:
When dividing 14 by 99, we get 0 with a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Fetch the next digit (5) from the dividend, attach it to 14 and continue: 145 / 99

Let's proceed to step 3:
145 divided by 99 is 1 with a remainder of 46.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 99 from 145, we get 46.
Include the next digit (8) from the dividend after 46, then repeat: 468 / 99

On to step 4:
468 divided by 99 is 4 with a remainder of 72.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Deduct 396 from 468 and we're left with 72.
Take the next digit (2) from the dividend and append it to 72, then repeat: 722 / 99

Moving on to step 5:
When dividing 722 by 99, we get 7 with a remainder of 29.
Put 7 as the next digit of the answer. 
Result so far: 147.0
Subtract 693 from 722 to get 29.
Bring next digit (8) of the dividend behind the 29 and repeat the process: 298 / 99

Step 6:
99 can be fit into 298 3 times, resulting in a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 1473.0
If we take 297 away from 298, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
99 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 1473.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
100 divided by 99 is 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 1473.01
Deduct 99 from 100 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 9:
99 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 1473.01
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
100 divided by 99 is 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1473.0101
Subtract 99 from 100 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 11:
When dividing 10 by 99, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 1473.0101
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 12:
The number 99 fits into 100 1 times, leaving a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1473.010101
If we take 99 away from 100, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 13:
The number 99 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 1473.010101
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 14:
When dividing 100 by 99, we get 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1473.01010101
Deduct 99 from 100 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Our division results in 1473.01010101 with a remaining 1e-09.
