We look at the division of 926663 by 99 
The aim is to understand the frequency of 99 in 926663.

Advancing to step 1:
99 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (2) from the dividend and append it to 9, then repeat: 92 / 99

On to step 2:
If we divide 92 by 99, we get 0 and a remainder of 92.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 92 leaves us with 92.
Grab the next digit (6) from the dividend, add it to 92, then carry on: 926 / 99

Moving on to step 3:
If we divide 926 by 99, we get 9 and a remainder of 35.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 891 from 926 and we're left with 35.
Take the next digit (6) from the dividend and append it to 35, then repeat: 356 / 99

Let's proceed to step 4:
99 can be fit into 356 3 times, resulting in a remainder of 59.
Put 3 as the next digit of the answer. 
Result so far: 93.0
If we take 297 away from 356, we end up with 59.
Append the next digit (6) from the dividend to 59 and continue with: 596 / 99

On to step 5:
If we divide 596 by 99, we get 6 and a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 936.0
If we take 594 away from 596, we end up with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 99

Going ahead to step 6:
The number 99 fits into 23 0 times, leaving a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 9360.0
The remainder is 23 after subtracting 0 from 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 7:
99 can be fit into 230 2 times, resulting in a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 9360.2
Subtracting 198 from 230 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 8:
99 can be fit into 320 3 times, resulting in a remainder of 23.
Record the quotient 3 as the next digit in the result. 
Result so far: 9360.23
The remainder is 23 after subtracting 297 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 9:
If we divide 230 by 99, we get 2 and a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 9360.232
If we subtract 198 from 230, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 10:
When dividing 320 by 99, we get 3 with a remainder of 23.
The next digit of our result is 3. 
Result so far: 9360.2323
If we take 297 away from 320, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 11:
When dividing 230 by 99, we get 2 with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 9360.23232
If we take 198 away from 230, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 12:
If we divide 320 by 99, we get 3 and a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 9360.232323
Subtract 297 from 320 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 13:
230 divided by 99 is 2 with a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 9360.2323232
Subtract 198 from 230 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 14:
If we divide 320 by 99, we get 3 and a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 9360.23232323
Deduct 297 from 320 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The final outcome is 9360.23232323, with a leftover of 2.3e-08.
