Let's divide 988481 by 99
The aim is to understand the frequency of 99 in 988481.

Going ahead to step 1:
99 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 99

Moving on to step 2:
If we divide 98 by 99, we get 0 and a remainder of 98.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 98 to get 98.
Fetch the next digit (8) from the dividend, attach it to 98 and continue: 988 / 99

On to step 3:
The number 99 fits into 988 9 times, leaving a remainder of 97.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 891 from 988 and we're left with 97.
Fetch the next digit (4) from the dividend, attach it to 97 and continue: 974 / 99

Going ahead to step 4:
The number 99 fits into 974 9 times, leaving a remainder of 83.
Write down 9 as next digit of the result. 
Result so far: 99.0
Subtracting 891 from 974 leaves us with 83.
Take the next digit (8) from the dividend and append it to 83, then repeat: 838 / 99

Let's proceed to step 5:
99 can be fit into 838 8 times, resulting in a remainder of 46.
Record the quotient 8 as the next digit in the result. 
Result so far: 998.0
The remainder is 46 after subtracting 792 from 838.
Bring next digit (1) of the dividend behind the 46 and repeat the process: 461 / 99

Advancing to step 6:
If we divide 461 by 99, we get 4 and a remainder of 65.
The number 4 becomes the next digit in our result. 
Result so far: 9984.0
Subtract 396 from 461 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 7:
99 goes into 650 6 times with a remainder of 56.
Record the quotient 6 as the next digit in the result. 
Result so far: 9984.6
The remainder is 56 after subtracting 594 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 8:
99 goes into 560 5 times with a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 9984.65
Deduct 495 from 560 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 9:
The number 99 fits into 650 6 times, leaving a remainder of 56.
Put 6 as the next digit of the answer. 
Result so far: 9984.656
If we take 594 away from 650, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 10:
The number 99 fits into 560 5 times, leaving a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 9984.6565
The remainder is 65 after subtracting 495 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 11:
99 can be fit into 650 6 times, resulting in a remainder of 56.
The next digit of our result is 6. 
Result so far: 9984.65656
Subtracting 594 from 650 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 12:
99 goes into 560 5 times with a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 9984.656565
If we take 495 away from 560, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 13:
The number 99 fits into 650 6 times, leaving a remainder of 56.
The number 6 becomes the next digit in our result. 
Result so far: 9984.6565656
Deduct 594 from 650 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 14:
99 goes into 560 5 times with a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 9984.65656565
Deduct 495 from 560 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

After the division, we end up with 9984.65656565 and a remainder of 6.5e-08.
