776411 ÷ 99 
The aim is to understand the frequency of 99 in 776411.

Moving on to step 1:
The number 99 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 99

Going ahead to step 2:
If we divide 77 by 99, we get 0 and a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Fetch the next digit (6) from the dividend, attach it to 77 and continue: 776 / 99

On to step 3:
The number 99 fits into 776 7 times, leaving a remainder of 83.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 83 after subtracting 693 from 776.
Include the next digit (4) from the dividend after 83, then repeat: 834 / 99

Going ahead to step 4:
When dividing 834 by 99, we get 8 with a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 78.0
Subtract 792 from 834 to get 42.
Fetch the next digit (1) from the dividend, attach it to 42 and continue: 421 / 99

Let's proceed to step 5:
99 can be fit into 421 4 times, resulting in a remainder of 25.
The next digit of our result is 4. 
Result so far: 784.0
Subtract 396 from 421 to get 25.
Grab the next digit (1) from the dividend, add it to 25, then carry on: 251 / 99

Let's proceed to step 6:
If we divide 251 by 99, we get 2 and a remainder of 53.
The number 2 becomes the next digit in our result. 
Result so far: 7842.0
If we take 198 away from 251, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 7:
The number 99 fits into 530 5 times, leaving a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 7842.5
Deduct 495 from 530 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 8:
If we divide 350 by 99, we get 3 and a remainder of 53.
Use 3 as the next digit of our solution. 
Result so far: 7842.53
If we subtract 297 from 350, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 9:
The number 99 fits into 530 5 times, leaving a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 7842.535
The remainder is 35 after subtracting 495 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 10:
When dividing 350 by 99, we get 3 with a remainder of 53.
The number 3 becomes the next digit in our result. 
Result so far: 7842.5353
Subtract 297 from 350 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 11:
The number 99 fits into 530 5 times, leaving a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 7842.53535
If we subtract 495 from 530, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 12:
If we divide 350 by 99, we get 3 and a remainder of 53.
The next digit of our result is 3. 
Result so far: 7842.535353
If we subtract 297 from 350, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 13:
If we divide 530 by 99, we get 5 and a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 7842.5353535
If we subtract 495 from 530, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 14:
The number 99 fits into 350 3 times, leaving a remainder of 53.
Use 3 as the next digit of our solution. 
Result so far: 7842.53535353
If we subtract 297 from 350, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

After the division, we end up with 7842.53535353 and a remainder of 5.3e-08.
