153156 ÷ 99 
The aim is to understand the frequency of 99 in 153156.

On to step 1:
When dividing 1 by 99, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 99

Advancing to step 2:
When dividing 15 by 99, we get 0 with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Take the next digit (3) from the dividend and append it to 15, then repeat: 153 / 99

Let's proceed to step 3:
If we divide 153 by 99, we get 1 and a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 99 from 153 to get 54.
Grab the next digit (1) from the dividend, add it to 54, then carry on: 541 / 99

On to step 4:
When dividing 541 by 99, we get 5 with a remainder of 46.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we take 495 away from 541, we end up with 46.
Append the next digit (5) from the dividend to 46 and continue with: 465 / 99

Moving on to step 5:
99 can be fit into 465 4 times, resulting in a remainder of 69.
Write down 4 as next digit of the result. 
Result so far: 154.0
Subtracting 396 from 465 leaves us with 69.
Include the next digit (6) from the dividend after 69, then repeat: 696 / 99

Going ahead to step 6:
99 can be fit into 696 7 times, resulting in a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 1547.0
The remainder is 3 after subtracting 693 from 696.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
The number 99 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 1547.0
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
99 goes into 300 3 times with a remainder of 3.
The next digit of our result is 3. 
Result so far: 1547.03
If we subtract 297 from 300, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 9:
30 divided by 99 is 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 1547.03
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 10:
If we divide 300 by 99, we get 3 and a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 1547.0303
If we take 297 away from 300, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 11:
30 divided by 99 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 1547.0303
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 12:
If we divide 300 by 99, we get 3 and a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 1547.030303
If we subtract 297 from 300, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 13:
30 divided by 99 is 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 1547.030303
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 14:
99 can be fit into 300 3 times, resulting in a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 1547.03030303
If we subtract 297 from 300, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final result is 1547.03030303 with a remainder of 3e-09.
