We look at the division of 23313172 by 899 
The aim is to understand the frequency of 899 in 23313172.

Let's proceed to step 1:
899 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 899

Moving on to step 2:
899 can be fit into 23 0 times, resulting in a remainder of 23.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 23, we end up with 23.
Grab the next digit (3) from the dividend, add it to 23, then carry on: 233 / 899

Going ahead to step 3:
899 goes into 233 0 times with a remainder of 233.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 233 and we're left with 233.
Take the next digit (1) from the dividend and append it to 233, then repeat: 2331 / 899

Advancing to step 4:
The number 899 fits into 2331 2 times, leaving a remainder of 533.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 1798 from 2331 to get 533.
Fetch the next digit (3) from the dividend, attach it to 533 and continue: 5333 / 899

Step 5:
If we divide 5333 by 899, we get 5 and a remainder of 838.
The next digit of our result is 5. 
Result so far: 25.0
If we take 4495 away from 5333, we end up with 838.
Grab the next digit (1) from the dividend, add it to 838, then carry on: 8381 / 899

Step 6:
If we divide 8381 by 899, we get 9 and a remainder of 290.
The next digit of our result is 9. 
Result so far: 259.0
Deduct 8091 from 8381 and we're left with 290.
Grab the next digit (7) from the dividend, add it to 290, then carry on: 2907 / 899

Advancing to step 7:
If we divide 2907 by 899, we get 3 and a remainder of 210.
Use 3 as the next digit of our solution. 
Result so far: 2593.0
If we subtract 2697 from 2907, we get 210.
Take the next digit (2) from the dividend and append it to 210, then repeat: 2102 / 899

Let's proceed to step 8:
The number 899 fits into 2102 2 times, leaving a remainder of 304.
Use 2 as the next digit of our solution. 
Result so far: 25932.0
If we subtract 1798 from 2102, we get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Step 9:
899 can be fit into 3040 3 times, resulting in a remainder of 343.
Record the quotient 3 as the next digit in the result. 
Result so far: 25932.3
If we subtract 2697 from 3040, we get 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Step 10:
When dividing 3430 by 899, we get 3 with a remainder of 733.
Put 3 as the next digit of the answer. 
Result so far: 25932.33
Subtract 2697 from 3430 to get 733.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7330, and continue the process.

The final outcome is 25932.33, with a leftover of 0.733.
