71960 ÷ 99 
The aim is to understand the frequency of 99 in 71960.

Let's proceed to step 1:
The number 99 fits into 7 0 times, leaving 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.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 99

Let's proceed to step 2:
When dividing 71 by 99, we get 0 with a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 71, we end up with 71.
Bring next digit (9) of the dividend behind the 71 and repeat the process: 719 / 99

Moving on to step 3:
When dividing 719 by 99, we get 7 with a remainder of 26.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 693 from 719 leaves us with 26.
Append the next digit (6) from the dividend to 26 and continue with: 266 / 99

Moving on to step 4:
The number 99 fits into 266 2 times, leaving a remainder of 68.
The number 2 becomes the next digit in our result. 
Result so far: 72.0
The remainder is 68 after subtracting 198 from 266.
Fetch the next digit (0) from the dividend, attach it to 68 and continue: 680 / 99

Advancing to step 5:
When dividing 680 by 99, we get 6 with a remainder of 86.
Put 6 as the next digit of the answer. 
Result so far: 726.0
Subtracting 594 from 680 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Step 6:
99 can be fit into 860 8 times, resulting in a remainder of 68.
The number 8 becomes the next digit in our result. 
Result so far: 726.8
Deduct 792 from 860 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 7:
99 goes into 680 6 times with a remainder of 86.
Record the quotient 6 as the next digit in the result. 
Result so far: 726.86
If we subtract 594 from 680, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Going ahead to step 8:
860 divided by 99 is 8 with a remainder of 68.
The next digit of our result is 8. 
Result so far: 726.868
The remainder is 68 after subtracting 792 from 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 9:
99 can be fit into 680 6 times, resulting in a remainder of 86.
Use 6 as the next digit of our solution. 
Result so far: 726.8686
The remainder is 86 after subtracting 594 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Going ahead to step 10:
When dividing 860 by 99, we get 8 with a remainder of 68.
Write down 8 as next digit of the result. 
Result so far: 726.86868
Subtracting 792 from 860 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 11:
The number 99 fits into 680 6 times, leaving a remainder of 86.
Put 6 as the next digit of the answer. 
Result so far: 726.868686
Subtracting 594 from 680 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Step 12:
The number 99 fits into 860 8 times, leaving a remainder of 68.
Write down 8 as next digit of the result. 
Result so far: 726.8686868
Deduct 792 from 860 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 13:
If we divide 680 by 99, we get 6 and a remainder of 86.
Write down 6 as next digit of the result. 
Result so far: 726.86868686
Deduct 594 from 680 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

The final outcome is 726.86868686, with a leftover of 8.6e-08.
