We're dividing 777449 by 99 
The aim is to understand the frequency of 99 in 777449.

Let's proceed to step 1:
The number 99 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 99

Let's proceed to step 2:
The number 99 fits into 77 0 times, leaving a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Fetch the next digit (7) from the dividend, attach it to 77 and continue: 777 / 99

Advancing to step 3:
99 can be fit into 777 7 times, resulting in a remainder of 84.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 693 from 777, we get 84.
Grab the next digit (4) from the dividend, add it to 84, then carry on: 844 / 99

Going ahead to step 4:
99 goes into 844 8 times with a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 78.0
Deduct 792 from 844 and we're left with 52.
Grab the next digit (4) from the dividend, add it to 52, then carry on: 524 / 99

On to step 5:
When dividing 524 by 99, we get 5 with a remainder of 29.
Record the quotient 5 as the next digit in the result. 
Result so far: 785.0
The remainder is 29 after subtracting 495 from 524.
Append the next digit (9) from the dividend to 29 and continue with: 299 / 99

Going ahead to step 6:
The number 99 fits into 299 3 times, leaving a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 7853.0
Subtracting 297 from 299 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.

Advancing to step 7:
If we divide 20 by 99, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 7853.0
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.

Let's proceed to step 8:
When dividing 200 by 99, we get 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 7853.02
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.

On to step 9:
20 divided by 99 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 7853.02
The remainder is 20 after subtracting 0 from 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 10:
99 can be fit into 200 2 times, resulting in a remainder of 2.
The next digit of our result is 2. 
Result so far: 7853.0202
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:
When dividing 20 by 99, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 7853.0202
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.

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: 7853.020202
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.

Step 13:
99 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 7853.020202
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.

On to step 14:
If we divide 200 by 99, we get 2 and a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 7853.02020202
If we subtract 198 from 200, we 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.

In conclusion, the division gives 7853.02020202 with a balance of 2e-09.
