We look at the division of 775343 by 99 
The aim is to understand the frequency of 99 in 775343.

Moving on to step 1:
When dividing 7 by 99, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 99

Moving on to step 2:
99 can be fit into 77 0 times, resulting in a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Append the next digit (5) from the dividend to 77 and continue with: 775 / 99

Going ahead to step 3:
99 goes into 775 7 times with a remainder of 82.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 693 from 775 leaves us with 82.
Append the next digit (3) from the dividend to 82 and continue with: 823 / 99

Let's proceed to step 4:
When dividing 823 by 99, we get 8 with a remainder of 31.
Put 8 as the next digit of the answer. 
Result so far: 78.0
The remainder is 31 after subtracting 792 from 823.
Append the next digit (4) from the dividend to 31 and continue with: 314 / 99

Going ahead to step 5:
99 goes into 314 3 times with a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 783.0
Subtracting 297 from 314 leaves us with 17.
Include the next digit (3) from the dividend after 17, then repeat: 173 / 99

On to step 6:
173 divided by 99 is 1 with a remainder of 74.
Record the quotient 1 as the next digit in the result. 
Result so far: 7831.0
Deduct 99 from 173 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 7:
The number 99 fits into 740 7 times, leaving a remainder of 47.
Record the quotient 7 as the next digit in the result. 
Result so far: 7831.7
If we subtract 693 from 740, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 8:
99 goes into 470 4 times with a remainder of 74.
The number 4 becomes the next digit in our result. 
Result so far: 7831.74
If we subtract 396 from 470, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 9:
The number 99 fits into 740 7 times, leaving a remainder of 47.
The number 7 becomes the next digit in our result. 
Result so far: 7831.747
If we subtract 693 from 740, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 10:
99 goes into 470 4 times with a remainder of 74.
The next digit of our result is 4. 
Result so far: 7831.7474
If we subtract 396 from 470, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 11:
99 can be fit into 740 7 times, resulting in a remainder of 47.
The next digit of our result is 7. 
Result so far: 7831.74747
If we take 693 away from 740, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 12:
99 goes into 470 4 times with a remainder of 74.
Put 4 as the next digit of the answer. 
Result so far: 7831.747474
If we take 396 away from 470, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 13:
When dividing 740 by 99, we get 7 with a remainder of 47.
Put 7 as the next digit of the answer. 
Result so far: 7831.7474747
Subtracting 693 from 740 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 14:
99 goes into 470 4 times with a remainder of 74.
Use 4 as the next digit of our solution. 
Result so far: 7831.74747474
Deduct 396 from 470 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Our division results in 7831.74747474 with a remaining 7.4e-08.
