We're dividing 75466024 by 99 
The aim is to understand the frequency of 99 in 75466024.

On to step 1:
When dividing 7 by 99, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 99

Step 2:
The number 99 fits into 75 0 times, leaving a remainder of 75.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 75 after subtracting 0 from 75.
Bring next digit (4) of the dividend behind the 75 and repeat the process: 754 / 99

Step 3:
754 divided by 99 is 7 with a remainder of 61.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 693 from 754 to get 61.
Grab the next digit (6) from the dividend, add it to 61, then carry on: 616 / 99

On to step 4:
When dividing 616 by 99, we get 6 with a remainder of 22.
The next digit of our result is 6. 
Result so far: 76.0
The remainder is 22 after subtracting 594 from 616.
Append the next digit (6) from the dividend to 22 and continue with: 226 / 99

On to step 5:
99 goes into 226 2 times with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 762.0
Subtract 198 from 226 to get 28.
Fetch the next digit (0) from the dividend, attach it to 28 and continue: 280 / 99

Going ahead to step 6:
99 goes into 280 2 times with a remainder of 82.
The next digit of our result is 2. 
Result so far: 7622.0
Subtract 198 from 280 to get 82.
Take the next digit (2) from the dividend and append it to 82, then repeat: 822 / 99

Moving on to step 7:
When dividing 822 by 99, we get 8 with a remainder of 30.
Record the quotient 8 as the next digit in the result. 
Result so far: 76228.0
If we subtract 792 from 822, we get 30.
Append the next digit (4) from the dividend to 30 and continue with: 304 / 99

Advancing to step 8:
99 can be fit into 304 3 times, resulting in a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 762283.0
Deduct 297 from 304 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 9:
When dividing 70 by 99, we get 0 with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 762283.0
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 10:
99 goes into 700 7 times with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 762283.07
If we subtract 693 from 700, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 11:
If we divide 70 by 99, we get 0 and a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 762283.07
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 12:
If we divide 700 by 99, we get 7 and a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 762283.0707
The remainder is 7 after subtracting 693 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 13:
If we divide 70 by 99, we get 0 and a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 762283.0707
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 14:
99 goes into 700 7 times with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 762283.070707
The remainder is 7 after subtracting 693 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 15:
99 can be fit into 70 0 times, resulting in a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 762283.070707
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 16:
When dividing 700 by 99, we get 7 with a remainder of 7.
The next digit of our result is 7. 
Result so far: 762283.07070707
If we subtract 693 from 700, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Our division results in 762283.07070707 with a remaining 7e-09.
