We divide 989932 by 99
The aim is to understand the frequency of 99 in 989932.

Step 1:
9 divided by 99 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 99

On to step 2:
If we divide 98 by 99, we get 0 and a remainder of 98.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 98 to get 98.
Take the next digit (9) from the dividend and append it to 98, then repeat: 989 / 99

Going ahead to step 3:
When dividing 989 by 99, we get 9 with a remainder of 98.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 891 from 989 and we're left with 98.
Bring next digit (9) of the dividend behind the 98 and repeat the process: 989 / 99

Advancing to step 4:
The number 99 fits into 989 9 times, leaving a remainder of 98.
Record the quotient 9 as the next digit in the result. 
Result so far: 99.0
If we subtract 891 from 989, we get 98.
Append the next digit (3) from the dividend to 98 and continue with: 983 / 99

On to step 5:
The number 99 fits into 983 9 times, leaving a remainder of 92.
Write down 9 as next digit of the result. 
Result so far: 999.0
If we take 891 away from 983, we end up with 92.
Append the next digit (2) from the dividend to 92 and continue with: 922 / 99

Going ahead to step 6:
99 goes into 922 9 times with a remainder of 31.
Write down 9 as next digit of the result. 
Result so far: 9999.0
Deduct 891 from 922 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 7:
310 divided by 99 is 3 with a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 9999.3
Subtract 297 from 310 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 8:
99 goes into 130 1 times with a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 9999.31
If we take 99 away from 130, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 9:
99 can be fit into 310 3 times, resulting in a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 9999.313
If we subtract 297 from 310, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 10:
When dividing 130 by 99, we get 1 with a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 9999.3131
Deduct 99 from 130 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 11:
The number 99 fits into 310 3 times, leaving a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 9999.31313
Deduct 297 from 310 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 12:
The number 99 fits into 130 1 times, leaving a remainder of 31.
Write down 1 as next digit of the result. 
Result so far: 9999.313131
Subtracting 99 from 130 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 13:
If we divide 310 by 99, we get 3 and a remainder of 13.
Use 3 as the next digit of our solution. 
Result so far: 9999.3131313
Subtract 297 from 310 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 14:
99 can be fit into 130 1 times, resulting in a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 9999.31313131
Subtracting 99 from 130 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Our division results in 9999.31313131 with a remaining 3.1e-08.
