We look at the division of 445306 by 99 
The aim is to understand the frequency of 99 in 445306.

On to step 1:
The number 99 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 99

Going ahead to step 2:
99 goes into 44 0 times with a remainder of 44.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 44 and we're left with 44.
Append the next digit (5) from the dividend to 44 and continue with: 445 / 99

Advancing to step 3:
The number 99 fits into 445 4 times, leaving a remainder of 49.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 396 from 445 to get 49.
Bring next digit (3) of the dividend behind the 49 and repeat the process: 493 / 99

Let's proceed to step 4:
99 goes into 493 4 times with a remainder of 97.
Use 4 as the next digit of our solution. 
Result so far: 44.0
Subtract 396 from 493 to get 97.
Include the next digit (0) from the dividend after 97, then repeat: 970 / 99

Advancing to step 5:
99 goes into 970 9 times with a remainder of 79.
The next digit of our result is 9. 
Result so far: 449.0
If we subtract 891 from 970, we get 79.
Take the next digit (6) from the dividend and append it to 79, then repeat: 796 / 99

Going ahead to step 6:
When dividing 796 by 99, we get 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 4498.0
If we subtract 792 from 796, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
99 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 4498.0
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
When dividing 400 by 99, we get 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 4498.04
The remainder is 4 after subtracting 396 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
40 divided by 99 is 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 4498.04
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 10:
400 divided by 99 is 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 4498.0404
Deduct 396 from 400 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 11:
When dividing 40 by 99, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 4498.0404
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 12:
99 goes into 400 4 times with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 4498.040404
The remainder is 4 after subtracting 396 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 13:
99 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 4498.040404
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 14:
When dividing 400 by 99, we get 4 with a remainder of 4.
The next digit of our result is 4. 
Result so far: 4498.04040404
Subtracting 396 from 400 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 4498.04040404 with a remaining 4e-09.
