We divide 396501 by 99
The aim is to understand the frequency of 99 in 396501.

Let's proceed to step 1:
3 divided by 99 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 99

Advancing to step 2:
39 divided by 99 is 0 with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Grab the next digit (6) from the dividend, add it to 39, then carry on: 396 / 99

Moving on to step 3:
If we divide 396 by 99, we get 4 and a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 396 from 396 and we're left with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 99

Step 4:
5 divided by 99 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
If we take 0 away from 5, we end up with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 99

Let's proceed to step 5:
When dividing 50 by 99, we get 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 400.0
Subtract 0 from 50 to get 50.
Grab the next digit (1) from the dividend, add it to 50, then carry on: 501 / 99

Going ahead to step 6:
99 goes into 501 5 times with a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 4005.0
If we subtract 495 from 501, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
99 can be fit into 60 0 times, resulting in a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 4005.0
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 8:
When dividing 600 by 99, we get 6 with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 4005.06
The remainder is 6 after subtracting 594 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 9:
If we divide 60 by 99, we get 0 and a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 4005.06
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 10:
99 can be fit into 600 6 times, resulting in a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 4005.0606
Subtracting 594 from 600 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 11:
60 divided by 99 is 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 4005.0606
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 12:
99 can be fit into 600 6 times, resulting in a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 4005.060606
The remainder is 6 after subtracting 594 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 13:
The number 99 fits into 60 0 times, leaving a remainder of 60.
The next digit of our result is 0. 
Result so far: 4005.060606
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 14:
When dividing 600 by 99, we get 6 with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 4005.06060606
If we take 594 away from 600, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The quotient of the division is 4005.06060606, and the remainder is 6e-09.
