28385925 ÷ 899 
The aim is to understand the frequency of 899 in 28385925.

Going ahead to step 1:
899 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 899

Moving on to step 2:
When dividing 28 by 899, we get 0 with a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Append the next digit (3) from the dividend to 28 and continue with: 283 / 899

Advancing to step 3:
When dividing 283 by 899, we get 0 with a remainder of 283.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 283 to get 283.
Take the next digit (8) from the dividend and append it to 283, then repeat: 2838 / 899

Going ahead to step 4:
899 goes into 2838 3 times with a remainder of 141.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 141 after subtracting 2697 from 2838.
Fetch the next digit (5) from the dividend, attach it to 141 and continue: 1415 / 899

Going ahead to step 5:
899 can be fit into 1415 1 times, resulting in a remainder of 516.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
Subtract 899 from 1415 to get 516.
Fetch the next digit (9) from the dividend, attach it to 516 and continue: 5169 / 899

Step 6:
The number 899 fits into 5169 5 times, leaving a remainder of 674.
Use 5 as the next digit of our solution. 
Result so far: 315.0
If we take 4495 away from 5169, we end up with 674.
Append the next digit (2) from the dividend to 674 and continue with: 6742 / 899

Step 7:
When dividing 6742 by 899, we get 7 with a remainder of 449.
Put 7 as the next digit of the answer. 
Result so far: 3157.0
If we take 6293 away from 6742, we end up with 449.
Bring next digit (5) of the dividend behind the 449 and repeat the process: 4495 / 899

Going ahead to step 8:
4495 divided by 899 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 31575.0
Deduct 4495 from 4495 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
899 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 31575.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
899 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 31575.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 31575.0, and the remainder is 0.0.
