7116 divided by 99 
The aim is to understand the frequency of 99 in 7116.

On to step 1:
When dividing 7 by 99, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 99

Let's proceed to step 2:
71 divided by 99 is 0 with a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 71 and we're left with 71.
Append the next digit (1) from the dividend to 71 and continue with: 711 / 99

Advancing to step 3:
When dividing 711 by 99, we get 7 with a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 18 after subtracting 693 from 711.
Take the next digit (6) from the dividend and append it to 18, then repeat: 186 / 99

Let's proceed to step 4:
The number 99 fits into 186 1 times, leaving a remainder of 87.
Record the quotient 1 as the next digit in the result. 
Result so far: 71.0
The remainder is 87 after subtracting 99 from 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

On to step 5:
99 can be fit into 870 8 times, resulting in a remainder of 78.
The next digit of our result is 8. 
Result so far: 71.8
If we take 792 away from 870, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 6:
The number 99 fits into 780 7 times, leaving a remainder of 87.
Use 7 as the next digit of our solution. 
Result so far: 71.87
Deduct 693 from 780 and we're left with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Advancing to step 7:
When dividing 870 by 99, we get 8 with a remainder of 78.
The next digit of our result is 8. 
Result so far: 71.878
If we subtract 792 from 870, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 8:
The number 99 fits into 780 7 times, leaving a remainder of 87.
Use 7 as the next digit of our solution. 
Result so far: 71.8787
Subtracting 693 from 780 leaves us with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Moving on to step 9:
99 goes into 870 8 times with a remainder of 78.
The next digit of our result is 8. 
Result so far: 71.87878
The remainder is 78 after subtracting 792 from 870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 10:
780 divided by 99 is 7 with a remainder of 87.
Put 7 as the next digit of the answer. 
Result so far: 71.878787
If we subtract 693 from 780, we get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

On to step 11:
99 goes into 870 8 times with a remainder of 78.
The next digit of our result is 8. 
Result so far: 71.8787878
If we take 792 away from 870, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 12:
When dividing 780 by 99, we get 7 with a remainder of 87.
The number 7 becomes the next digit in our result. 
Result so far: 71.87878787
Subtracting 693 from 780 leaves us with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.
