87883 divided by 99 
The aim is to understand the frequency of 99 in 87883.

Advancing to step 1:
99 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 99

Let's proceed to step 2:
87 divided by 99 is 0 with a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 87 after subtracting 0 from 87.
Fetch the next digit (8) from the dividend, attach it to 87 and continue: 878 / 99

Moving on to step 3:
If we divide 878 by 99, we get 8 and a remainder of 86.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 86 after subtracting 792 from 878.
Include the next digit (8) from the dividend after 86, then repeat: 868 / 99

Moving on to step 4:
99 can be fit into 868 8 times, resulting in a remainder of 76.
Record the quotient 8 as the next digit in the result. 
Result so far: 88.0
Deduct 792 from 868 and we're left with 76.
Fetch the next digit (3) from the dividend, attach it to 76 and continue: 763 / 99

Let's proceed to step 5:
If we divide 763 by 99, we get 7 and a remainder of 70.
Use 7 as the next digit of our solution. 
Result so far: 887.0
If we subtract 693 from 763, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 6:
99 can be fit into 700 7 times, resulting in a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 887.7
If we take 693 away from 700, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
The number 99 fits into 70 0 times, leaving a remainder of 70.
The next digit of our result is 0. 
Result so far: 887.7
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 8:
The number 99 fits into 700 7 times, leaving a remainder of 7.
The next digit of our result is 7. 
Result so far: 887.707
Subtracting 693 from 700 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 9:
The number 99 fits into 70 0 times, leaving a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 887.707
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 10:
99 can be fit into 700 7 times, resulting in a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 887.70707
Deduct 693 from 700 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 11:
99 goes into 70 0 times with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 887.70707
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 12:
When dividing 700 by 99, we get 7 with a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 887.7070707
If we take 693 away from 700, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 13:
The number 99 fits into 70 0 times, leaving a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 887.7070707
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Our division results in 887.7070707 with a remaining 7e-08.
