We're dividing 69900 by 99 
The aim is to understand the frequency of 99 in 69900.

Advancing to step 1:
When dividing 6 by 99, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 99

Moving on to step 2:
99 can be fit into 69 0 times, resulting in a remainder of 69.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 69, we get 69.
Append the next digit (9) from the dividend to 69 and continue with: 699 / 99

On to step 3:
99 can be fit into 699 7 times, resulting in a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 6 after subtracting 693 from 699.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 99

Let's proceed to step 4:
When dividing 60 by 99, we get 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 70.0
Deduct 0 from 60 and we're left with 60.
Grab the next digit (0) from the dividend, add it to 60, then carry on: 600 / 99

On to step 5:
99 goes into 600 6 times with a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 706.0
The remainder is 6 after subtracting 594 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 6:
99 can be fit into 60 0 times, resulting in a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 706.0
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 7:
600 divided by 99 is 6 with a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 706.06
If we take 594 away from 600, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
When dividing 60 by 99, we get 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 706.06
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 9:
When dividing 600 by 99, we get 6 with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 706.0606
Subtracting 594 from 600 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 10:
When dividing 60 by 99, we get 0 with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 706.0606
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 11:
600 divided by 99 is 6 with a remainder of 6.
The next digit of our result is 6. 
Result so far: 706.060606
If we subtract 594 from 600, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 12:
99 goes into 60 0 times with a remainder of 60.
The next digit of our result is 0. 
Result so far: 706.060606
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 13:
When dividing 600 by 99, we get 6 with a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 706.06060606
The remainder is 6 after subtracting 594 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

After the division, we end up with 706.06060606 and a remainder of 6e-09.
