We divide 609958 by 99
The aim is to understand the frequency of 99 in 609958.

Step 1:
99 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 99

On to step 2:
If we divide 60 by 99, we get 0 and a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 60, we get 60.
Bring next digit (9) of the dividend behind the 60 and repeat the process: 609 / 99

On to step 3:
If we divide 609 by 99, we get 6 and a remainder of 15.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 15 after subtracting 594 from 609.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 99

Going ahead to step 4:
99 goes into 159 1 times with a remainder of 60.
Put 1 as the next digit of the answer. 
Result so far: 61.0
If we subtract 99 from 159, we get 60.
Fetch the next digit (5) from the dividend, attach it to 60 and continue: 605 / 99

Let's proceed to step 5:
The number 99 fits into 605 6 times, leaving a remainder of 11.
Put 6 as the next digit of the answer. 
Result so far: 616.0
Subtract 594 from 605 to get 11.
Bring next digit (8) of the dividend behind the 11 and repeat the process: 118 / 99

Moving on to step 6:
The number 99 fits into 118 1 times, leaving a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 6161.0
Subtracting 99 from 118 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 7:
The number 99 fits into 190 1 times, leaving a remainder of 91.
Use 1 as the next digit of our solution. 
Result so far: 6161.1
Subtract 99 from 190 to get 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Moving on to step 8:
The number 99 fits into 910 9 times, leaving a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 6161.19
Subtracting 891 from 910 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 9:
190 divided by 99 is 1 with a remainder of 91.
The next digit of our result is 1. 
Result so far: 6161.191
If we take 99 away from 190, we end up with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Moving on to step 10:
99 goes into 910 9 times with a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 6161.1919
If we subtract 891 from 910, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 11:
99 can be fit into 190 1 times, resulting in a remainder of 91.
The next digit of our result is 1. 
Result so far: 6161.19191
The remainder is 91 after subtracting 99 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Advancing to step 12:
When dividing 910 by 99, we get 9 with a remainder of 19.
The next digit of our result is 9. 
Result so far: 6161.191919
Deduct 891 from 910 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 13:
99 goes into 190 1 times with a remainder of 91.
Use 1 as the next digit of our solution. 
Result so far: 6161.1919191
The remainder is 91 after subtracting 99 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Going ahead to step 14:
If we divide 910 by 99, we get 9 and a remainder of 19.
The next digit of our result is 9. 
Result so far: 6161.19191919
Deduct 891 from 910 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Our division results in 6161.19191919 with a remaining 1.9e-08.
