We look at the division of 777051 by 99 
The aim is to understand the frequency of 99 in 777051.

Going ahead to step 1:
99 can be fit into 7 0 times, resulting in 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.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 99

Going ahead to step 2:
When dividing 77 by 99, we get 0 with a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Include the next digit (7) from the dividend after 77, then repeat: 777 / 99

Step 3:
If we divide 777 by 99, we get 7 and a remainder of 84.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 693 away from 777, we end up with 84.
Append the next digit (0) from the dividend to 84 and continue with: 840 / 99

Advancing to step 4:
840 divided by 99 is 8 with a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
Subtract 792 from 840 to get 48.
Append the next digit (5) from the dividend to 48 and continue with: 485 / 99

Moving on to step 5:
The number 99 fits into 485 4 times, leaving a remainder of 89.
Record the quotient 4 as the next digit in the result. 
Result so far: 784.0
Subtracting 396 from 485 leaves us with 89.
Fetch the next digit (1) from the dividend, attach it to 89 and continue: 891 / 99

Moving on to step 6:
891 divided by 99 is 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 7849.0
Subtracting 891 from 891 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
99 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 7849.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
99 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 7849.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 7849.0 with a remaining 0.0.
