We look at the division of 786729 by 99 
The aim is to understand the frequency of 99 in 786729.

Moving on to step 1:
99 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 99

Step 2:
99 goes into 78 0 times with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Take the next digit (6) from the dividend and append it to 78, then repeat: 786 / 99

Let's proceed to step 3:
If we divide 786 by 99, we get 7 and a remainder of 93.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 693 from 786, we get 93.
Append the next digit (7) from the dividend to 93 and continue with: 937 / 99

Moving on to step 4:
99 goes into 937 9 times with a remainder of 46.
Record the quotient 9 as the next digit in the result. 
Result so far: 79.0
Subtract 891 from 937 to get 46.
Grab the next digit (2) from the dividend, add it to 46, then carry on: 462 / 99

Let's proceed to step 5:
99 goes into 462 4 times with a remainder of 66.
Write down 4 as next digit of the result. 
Result so far: 794.0
Deduct 396 from 462 and we're left with 66.
Fetch the next digit (9) from the dividend, attach it to 66 and continue: 669 / 99

Let's proceed to step 6:
If we divide 669 by 99, we get 6 and a remainder of 75.
The number 6 becomes the next digit in our result. 
Result so far: 7946.0
Subtracting 594 from 669 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 7:
750 divided by 99 is 7 with a remainder of 57.
The next digit of our result is 7. 
Result so far: 7946.7
If we subtract 693 from 750, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 8:
99 goes into 570 5 times with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 7946.75
Subtract 495 from 570 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 9:
If we divide 750 by 99, we get 7 and a remainder of 57.
Use 7 as the next digit of our solution. 
Result so far: 7946.757
Subtract 693 from 750 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 10:
570 divided by 99 is 5 with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 7946.7575
Subtracting 495 from 570 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 11:
When dividing 750 by 99, we get 7 with a remainder of 57.
The number 7 becomes the next digit in our result. 
Result so far: 7946.75757
If we take 693 away from 750, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 12:
When dividing 570 by 99, we get 5 with a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 7946.757575
Deduct 495 from 570 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 13:
99 goes into 750 7 times with a remainder of 57.
Put 7 as the next digit of the answer. 
Result so far: 7946.7575757
The remainder is 57 after subtracting 693 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 14:
The number 99 fits into 570 5 times, leaving a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 7946.75757575
If we take 495 away from 570, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

The quotient of the division is 7946.75757575, and the remainder is 7.5e-08.
