We divide 983115 by 99
The aim is to understand the frequency of 99 in 983115.

On to step 1:
99 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 99

Step 2:
99 goes into 98 0 times with a remainder of 98.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 98 to get 98.
Append the next digit (3) from the dividend to 98 and continue with: 983 / 99

Moving on to step 3:
If we divide 983 by 99, we get 9 and a remainder of 92.
Put 9 as the next digit of the answer. 
Result so far: 9.0
The remainder is 92 after subtracting 891 from 983.
Take the next digit (1) from the dividend and append it to 92, then repeat: 921 / 99

On to step 4:
99 goes into 921 9 times with a remainder of 30.
The number 9 becomes the next digit in our result. 
Result so far: 99.0
The remainder is 30 after subtracting 891 from 921.
Fetch the next digit (1) from the dividend, attach it to 30 and continue: 301 / 99

Going ahead to step 5:
When dividing 301 by 99, we get 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 993.0
Deduct 297 from 301 and we're left with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 99

Moving on to step 6:
If we divide 45 by 99, we get 0 and a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 9930.0
If we take 0 away from 45, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 7:
99 can be fit into 450 4 times, resulting in a remainder of 54.
The number 4 becomes the next digit in our result. 
Result so far: 9930.4
The remainder is 54 after subtracting 396 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 8:
The number 99 fits into 540 5 times, leaving a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 9930.45
If we take 495 away from 540, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 9:
When dividing 450 by 99, we get 4 with a remainder of 54.
Put 4 as the next digit of the answer. 
Result so far: 9930.454
Deduct 396 from 450 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 10:
When dividing 540 by 99, we get 5 with a remainder of 45.
The next digit of our result is 5. 
Result so far: 9930.4545
Subtracting 495 from 540 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 11:
The number 99 fits into 450 4 times, leaving a remainder of 54.
Use 4 as the next digit of our solution. 
Result so far: 9930.45454
If we subtract 396 from 450, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 12:
99 can be fit into 540 5 times, resulting in a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 9930.454545
The remainder is 45 after subtracting 495 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 13:
If we divide 450 by 99, we get 4 and a remainder of 54.
Write down 4 as next digit of the result. 
Result so far: 9930.4545454
Subtract 396 from 450 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 14:
99 can be fit into 540 5 times, resulting in a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 9930.45454545
Subtracting 495 from 540 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final outcome is 9930.45454545, with a leftover of 4.5e-08.
