We divide 766699 by 99
The aim is to understand the frequency of 99 in 766699.

Going ahead to step 1:
The number 99 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 99

Step 2:
99 goes into 76 0 times with a remainder of 76.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 76 and we're left with 76.
Take the next digit (6) from the dividend and append it to 76, then repeat: 766 / 99

Going ahead to step 3:
The number 99 fits into 766 7 times, leaving a remainder of 73.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 693 from 766, we get 73.
Include the next digit (6) from the dividend after 73, then repeat: 736 / 99

Step 4:
If we divide 736 by 99, we get 7 and a remainder of 43.
The next digit of our result is 7. 
Result so far: 77.0
Subtracting 693 from 736 leaves us with 43.
Bring next digit (9) of the dividend behind the 43 and repeat the process: 439 / 99

Going ahead to step 5:
439 divided by 99 is 4 with a remainder of 43.
Write down 4 as next digit of the result. 
Result so far: 774.0
If we subtract 396 from 439, we get 43.
Grab the next digit (9) from the dividend, add it to 43, then carry on: 439 / 99

On to step 6:
If we divide 439 by 99, we get 4 and a remainder of 43.
Record the quotient 4 as the next digit in the result. 
Result so far: 7744.0
Deduct 396 from 439 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 7:
When dividing 430 by 99, we get 4 with a remainder of 34.
Put 4 as the next digit of the answer. 
Result so far: 7744.4
Deduct 396 from 430 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 8:
The number 99 fits into 340 3 times, leaving a remainder of 43.
The next digit of our result is 3. 
Result so far: 7744.43
Deduct 297 from 340 and we're left with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 9:
The number 99 fits into 430 4 times, leaving a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 7744.434
Subtract 396 from 430 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 10:
99 can be fit into 340 3 times, resulting in a remainder of 43.
Record the quotient 3 as the next digit in the result. 
Result so far: 7744.4343
Subtracting 297 from 340 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 11:
99 can be fit into 430 4 times, resulting in a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 7744.43434
The remainder is 34 after subtracting 396 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 12:
If we divide 340 by 99, we get 3 and a remainder of 43.
Put 3 as the next digit of the answer. 
Result so far: 7744.434343
If we subtract 297 from 340, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 13:
When dividing 430 by 99, we get 4 with a remainder of 34.
Use 4 as the next digit of our solution. 
Result so far: 7744.4343434
Subtract 396 from 430 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 14:
99 goes into 340 3 times with a remainder of 43.
The next digit of our result is 3. 
Result so far: 7744.43434343
If we subtract 297 from 340, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Our division results in 7744.43434343 with a remaining 4.3e-08.
