221445 ÷ 99 
The aim is to understand the frequency of 99 in 221445.

Moving on to step 1:
99 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 99

Moving on to step 2:
If we divide 22 by 99, we get 0 and a remainder of 22.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 22 leaves us with 22.
Grab the next digit (1) from the dividend, add it to 22, then carry on: 221 / 99

On to step 3:
99 can be fit into 221 2 times, resulting in a remainder of 23.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 23 after subtracting 198 from 221.
Append the next digit (4) from the dividend to 23 and continue with: 234 / 99

Let's proceed to step 4:
234 divided by 99 is 2 with a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 22.0
The remainder is 36 after subtracting 198 from 234.
Append the next digit (4) from the dividend to 36 and continue with: 364 / 99

On to step 5:
99 can be fit into 364 3 times, resulting in a remainder of 67.
Write down 3 as next digit of the result. 
Result so far: 223.0
Subtract 297 from 364 to get 67.
Grab the next digit (5) from the dividend, add it to 67, then carry on: 675 / 99

Moving on to step 6:
99 can be fit into 675 6 times, resulting in a remainder of 81.
The number 6 becomes the next digit in our result. 
Result so far: 2236.0
Subtract 594 from 675 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 7:
When dividing 810 by 99, we get 8 with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 2236.8
Deduct 792 from 810 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 8:
180 divided by 99 is 1 with a remainder of 81.
Record the quotient 1 as the next digit in the result. 
Result so far: 2236.81
If we subtract 99 from 180, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 9:
99 can be fit into 810 8 times, resulting in a remainder of 18.
The next digit of our result is 8. 
Result so far: 2236.818
Subtracting 792 from 810 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 10:
The number 99 fits into 180 1 times, leaving a remainder of 81.
Write down 1 as next digit of the result. 
Result so far: 2236.8181
The remainder is 81 after subtracting 99 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Let's proceed to step 11:
If we divide 810 by 99, we get 8 and a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 2236.81818
Subtract 792 from 810 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 12:
If we divide 180 by 99, we get 1 and a remainder of 81.
The next digit of our result is 1. 
Result so far: 2236.818181
If we take 99 away from 180, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 13:
810 divided by 99 is 8 with a remainder of 18.
The next digit of our result is 8. 
Result so far: 2236.8181818
Subtract 792 from 810 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 14:
The number 99 fits into 180 1 times, leaving a remainder of 81.
Put 1 as the next digit of the answer. 
Result so far: 2236.81818181
If we subtract 99 from 180, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

The quotient of the division is 2236.81818181, and the remainder is 8.1e-08.
