87422 ÷ 99 
The aim is to understand the frequency of 99 in 87422.

On to step 1:
99 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 99

Going ahead to step 2:
The number 99 fits into 87 0 times, leaving a remainder of 87.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 87, we get 87.
Bring next digit (4) of the dividend behind the 87 and repeat the process: 874 / 99

Step 3:
874 divided by 99 is 8 with a remainder of 82.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 792 from 874, we get 82.
Fetch the next digit (2) from the dividend, attach it to 82 and continue: 822 / 99

Moving on to step 4:
822 divided by 99 is 8 with a remainder of 30.
The next digit of our result is 8. 
Result so far: 88.0
If we take 792 away from 822, we end up with 30.
Include the next digit (2) from the dividend after 30, then repeat: 302 / 99

Moving on to step 5:
When dividing 302 by 99, we get 3 with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 883.0
If we subtract 297 from 302, we get 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 6:
If we divide 50 by 99, we get 0 and a remainder of 50.
The next digit of our result is 0. 
Result so far: 883.0
The remainder is 50 after subtracting 0 from 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 7:
If we divide 500 by 99, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 883.05
Subtract 495 from 500 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
50 divided by 99 is 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 883.05
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 9:
When dividing 500 by 99, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 883.0505
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 10:
50 divided by 99 is 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 883.0505
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.

Moving on to step 11:
99 goes into 500 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 883.050505
If we subtract 495 from 500, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 12:
If we divide 50 by 99, we get 0 and a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 883.050505
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.

Step 13:
99 goes into 500 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 883.05050505
If we subtract 495 from 500, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The quotient of the division is 883.05050505, and the remainder is 5e-09.
