We divide 667760 by 99
The aim is to understand the frequency of 99 in 667760.

Moving on to step 1:
99 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 99

Moving on to step 2:
When dividing 66 by 99, we get 0 with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Take the next digit (7) from the dividend and append it to 66, then repeat: 667 / 99

Let's proceed to step 3:
99 goes into 667 6 times with a remainder of 73.
Use 6 as the next digit of our solution. 
Result so far: 6.0
The remainder is 73 after subtracting 594 from 667.
Include the next digit (7) from the dividend after 73, then repeat: 737 / 99

Advancing to step 4:
99 goes into 737 7 times with a remainder of 44.
Use 7 as the next digit of our solution. 
Result so far: 67.0
Deduct 693 from 737 and we're left with 44.
Fetch the next digit (6) from the dividend, attach it to 44 and continue: 446 / 99

Moving on to step 5:
If we divide 446 by 99, we get 4 and a remainder of 50.
Use 4 as the next digit of our solution. 
Result so far: 674.0
Subtract 396 from 446 to get 50.
Append the next digit (0) from the dividend to 50 and continue with: 500 / 99

Step 6:
When dividing 500 by 99, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 6745.0
The remainder is 5 after subtracting 495 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
99 can be fit into 50 0 times, resulting in a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 6745.0
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 8:
500 divided by 99 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 6745.05
If we take 495 away from 500, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 9:
If we divide 50 by 99, we get 0 and a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 6745.05
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 10:
When dividing 500 by 99, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 6745.0505
The remainder is 5 after subtracting 495 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 11:
When dividing 50 by 99, we get 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 6745.0505
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 12:
When dividing 500 by 99, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 6745.050505
Deduct 495 from 500 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 13:
The number 99 fits into 50 0 times, leaving a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 6745.050505
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 14:
When dividing 500 by 99, we get 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 6745.05050505
Deduct 495 from 500 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 6745.05050505 and a remainder of 5e-09.
