787448 ÷ 99 
The aim is to understand the frequency of 99 in 787448.

Advancing to step 1:
99 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 99

Moving on to step 2:
99 can be fit into 78 0 times, resulting in a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Take the next digit (7) from the dividend and append it to 78, then repeat: 787 / 99

Going ahead to step 3:
99 goes into 787 7 times with a remainder of 94.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 693 away from 787, we end up with 94.
Append the next digit (4) from the dividend to 94 and continue with: 944 / 99

Going ahead to step 4:
99 goes into 944 9 times with a remainder of 53.
Write down 9 as next digit of the result. 
Result so far: 79.0
Subtract 891 from 944 to get 53.
Bring next digit (4) of the dividend behind the 53 and repeat the process: 534 / 99

On to step 5:
The number 99 fits into 534 5 times, leaving a remainder of 39.
Record the quotient 5 as the next digit in the result. 
Result so far: 795.0
If we subtract 495 from 534, we get 39.
Bring next digit (8) of the dividend behind the 39 and repeat the process: 398 / 99

Moving on to step 6:
The number 99 fits into 398 4 times, leaving a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 7954.0
Subtracting 396 from 398 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
99 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 7954.0
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
The number 99 fits into 200 2 times, leaving a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 7954.02
If we take 198 away from 200, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 9:
The number 99 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 7954.02
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 10:
The number 99 fits into 200 2 times, leaving a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 7954.0202
Subtract 198 from 200 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 11:
20 divided by 99 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 7954.0202
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 12:
The number 99 fits into 200 2 times, leaving a remainder of 2.
The next digit of our result is 2. 
Result so far: 7954.020202
If we take 198 away from 200, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 13:
99 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 7954.020202
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 14:
200 divided by 99 is 2 with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 7954.02020202
Deduct 198 from 200 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 7954.02020202 and a remainder of 2e-09.
