We divide 423869 by 99
The aim is to understand the frequency of 99 in 423869.

Let's proceed to step 1:
When dividing 4 by 99, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 99

Advancing to step 2:
If we divide 42 by 99, we get 0 and a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Take the next digit (3) from the dividend and append it to 42, then repeat: 423 / 99

On to step 3:
99 can be fit into 423 4 times, resulting in a remainder of 27.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 396 from 423, we get 27.
Bring next digit (8) of the dividend behind the 27 and repeat the process: 278 / 99

Advancing to step 4:
278 divided by 99 is 2 with a remainder of 80.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
Deduct 198 from 278 and we're left with 80.
Fetch the next digit (6) from the dividend, attach it to 80 and continue: 806 / 99

Step 5:
806 divided by 99 is 8 with a remainder of 14.
The next digit of our result is 8. 
Result so far: 428.0
Deduct 792 from 806 and we're left with 14.
Take the next digit (9) from the dividend and append it to 14, then repeat: 149 / 99

Step 6:
149 divided by 99 is 1 with a remainder of 50.
Use 1 as the next digit of our solution. 
Result so far: 4281.0
If we subtract 99 from 149, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 7:
When dividing 500 by 99, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 4281.5
Subtracting 495 from 500 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
99 can be fit into 50 0 times, resulting in a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 4281.5
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 9:
99 can be fit into 500 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 4281.505
Deduct 495 from 500 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 10:
If we divide 50 by 99, we get 0 and a remainder of 50.
The next digit of our result is 0. 
Result so far: 4281.505
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 11:
The number 99 fits into 500 5 times, leaving a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 4281.50505
If we subtract 495 from 500, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 12:
50 divided by 99 is 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 4281.50505
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 13:
If we divide 500 by 99, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 4281.5050505
Deduct 495 from 500 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 14:
If we divide 50 by 99, we get 0 and a remainder of 50.
The next digit of our result is 0. 
Result so far: 4281.5050505
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The quotient of the division is 4281.5050505, and the remainder is 5e-08.
