Let's divide 9926399 by 900
The aim is to understand the frequency of 900 in 9926399.

Step 1:
The number 900 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 900

Advancing to step 2:
99 divided by 900 is 0 with a remainder of 99.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 99 and we're left with 99.
Bring next digit (2) of the dividend behind the 99 and repeat the process: 992 / 900

On to step 3:
When dividing 992 by 900, we get 1 with a remainder of 92.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 900 from 992, we get 92.
Include the next digit (6) from the dividend after 92, then repeat: 926 / 900

Advancing to step 4:
If we divide 926 by 900, we get 1 and a remainder of 26.
Write down 1 as next digit of the result. 
Result so far: 11.0
Deduct 900 from 926 and we're left with 26.
Take the next digit (3) from the dividend and append it to 26, then repeat: 263 / 900

Let's proceed to step 5:
When dividing 263 by 900, we get 0 with a remainder of 263.
Record the quotient 0 as the next digit in the result. 
Result so far: 110.0
Subtract 0 from 263 to get 263.
Take the next digit (9) from the dividend and append it to 263, then repeat: 2639 / 900

On to step 6:
900 goes into 2639 2 times with a remainder of 839.
The next digit of our result is 2. 
Result so far: 1102.0
If we subtract 1800 from 2639, we get 839.
Bring next digit (9) of the dividend behind the 839 and repeat the process: 8399 / 900

Going ahead to step 7:
8399 divided by 900 is 9 with a remainder of 299.
The next digit of our result is 9. 
Result so far: 11029.0
Deduct 8100 from 8399 and we're left with 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Advancing to step 8:
If we divide 2990 by 900, we get 3 and a remainder of 290.
Record the quotient 3 as the next digit in the result. 
Result so far: 11029.3
If we take 2700 away from 2990, we end up with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Advancing to step 9:
900 goes into 2900 3 times with a remainder of 200.
The next digit of our result is 3. 
Result so far: 11029.33
Subtracting 2700 from 2900 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The quotient of the division is 11029.33, and the remainder is 0.2.
