76699 divided by 99 
The aim is to understand the frequency of 99 in 76699.

Moving on to step 1:
When dividing 7 by 99, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 99

Moving on to step 2:
99 goes into 76 0 times with a remainder of 76.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 76 leaves us with 76.
Take the next digit (6) from the dividend and append it to 76, then repeat: 766 / 99

Going ahead to step 3:
99 goes into 766 7 times with a remainder of 73.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 693 from 766 leaves us with 73.
Fetch the next digit (9) from the dividend, attach it to 73 and continue: 739 / 99

Step 4:
When dividing 739 by 99, we get 7 with a remainder of 46.
Record the quotient 7 as the next digit in the result. 
Result so far: 77.0
Deduct 693 from 739 and we're left with 46.
Fetch the next digit (9) from the dividend, attach it to 46 and continue: 469 / 99

On to step 5:
The number 99 fits into 469 4 times, leaving a remainder of 73.
Record the quotient 4 as the next digit in the result. 
Result so far: 774.0
The remainder is 73 after subtracting 396 from 469.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 6:
If we divide 730 by 99, we get 7 and a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 774.7
Subtract 693 from 730 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 7:
The number 99 fits into 370 3 times, leaving a remainder of 73.
Write down 3 as next digit of the result. 
Result so far: 774.73
Subtract 297 from 370 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 8:
99 goes into 730 7 times with a remainder of 37.
The number 7 becomes the next digit in our result. 
Result so far: 774.737
Subtract 693 from 730 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 9:
The number 99 fits into 370 3 times, leaving a remainder of 73.
Record the quotient 3 as the next digit in the result. 
Result so far: 774.7373
Subtracting 297 from 370 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 10:
The number 99 fits into 730 7 times, leaving a remainder of 37.
Put 7 as the next digit of the answer. 
Result so far: 774.73737
If we subtract 693 from 730, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 11:
99 can be fit into 370 3 times, resulting in a remainder of 73.
Write down 3 as next digit of the result. 
Result so far: 774.737373
The remainder is 73 after subtracting 297 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 12:
If we divide 730 by 99, we get 7 and a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 774.7373737
The remainder is 37 after subtracting 693 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 13:
370 divided by 99 is 3 with a remainder of 73.
Use 3 as the next digit of our solution. 
Result so far: 774.73737373
Subtract 297 from 370 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

After the division, we end up with 774.73737373 and a remainder of 7.3e-08.
