766504 ÷ 99 
The aim is to understand the frequency of 99 in 766504.

Advancing to step 1:
The number 99 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 99

Let's proceed to step 2:
99 can be fit into 76 0 times, resulting in a remainder of 76.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 76 leaves us with 76.
Grab the next digit (6) from the dividend, add it to 76, then carry on: 766 / 99

Going ahead to step 3:
The number 99 fits into 766 7 times, leaving a remainder of 73.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 693 from 766 to get 73.
Append the next digit (5) from the dividend to 73 and continue with: 735 / 99

Going ahead to step 4:
99 can be fit into 735 7 times, resulting in a remainder of 42.
Record the quotient 7 as the next digit in the result. 
Result so far: 77.0
If we subtract 693 from 735, we get 42.
Fetch the next digit (0) from the dividend, attach it to 42 and continue: 420 / 99

On to step 5:
420 divided by 99 is 4 with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 774.0
If we take 396 away from 420, we end up with 24.
Include the next digit (4) from the dividend after 24, then repeat: 244 / 99

Moving on to step 6:
99 goes into 244 2 times with a remainder of 46.
Use 2 as the next digit of our solution. 
Result so far: 7742.0
If we subtract 198 from 244, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 7:
When dividing 460 by 99, we get 4 with a remainder of 64.
Write down 4 as next digit of the result. 
Result so far: 7742.4
If we take 396 away from 460, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 8:
When dividing 640 by 99, we get 6 with a remainder of 46.
The number 6 becomes the next digit in our result. 
Result so far: 7742.46
If we take 594 away from 640, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 9:
When dividing 460 by 99, we get 4 with a remainder of 64.
The number 4 becomes the next digit in our result. 
Result so far: 7742.464
If we take 396 away from 460, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 10:
640 divided by 99 is 6 with a remainder of 46.
The number 6 becomes the next digit in our result. 
Result so far: 7742.4646
Subtracting 594 from 640 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 11:
If we divide 460 by 99, we get 4 and a remainder of 64.
Record the quotient 4 as the next digit in the result. 
Result so far: 7742.46464
Deduct 396 from 460 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 12:
When dividing 640 by 99, we get 6 with a remainder of 46.
The number 6 becomes the next digit in our result. 
Result so far: 7742.464646
If we subtract 594 from 640, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 13:
99 goes into 460 4 times with a remainder of 64.
The next digit of our result is 4. 
Result so far: 7742.4646464
If we subtract 396 from 460, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 14:
99 can be fit into 640 6 times, resulting in a remainder of 46.
Write down 6 as next digit of the result. 
Result so far: 7742.46464646
Subtract 594 from 640 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final outcome is 7742.46464646, with a leftover of 4.6e-08.
