18446801 divided by 899 
The aim is to understand the frequency of 899 in 18446801.

Let's proceed to step 1:
1 divided by 899 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 899

Going ahead to step 2:
When dividing 18 by 899, we get 0 with a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Take the next digit (4) from the dividend and append it to 18, then repeat: 184 / 899

On to step 3:
When dividing 184 by 899, we get 0 with a remainder of 184.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 184 after subtracting 0 from 184.
Grab the next digit (4) from the dividend, add it to 184, then carry on: 1844 / 899

Let's proceed to step 4:
The number 899 fits into 1844 2 times, leaving a remainder of 46.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 46 after subtracting 1798 from 1844.
Bring next digit (6) of the dividend behind the 46 and repeat the process: 466 / 899

Going ahead to step 5:
When dividing 466 by 899, we get 0 with a remainder of 466.
Write down 0 as next digit of the result. 
Result so far: 20.0
Subtract 0 from 466 to get 466.
Include the next digit (8) from the dividend after 466, then repeat: 4668 / 899

Advancing to step 6:
899 can be fit into 4668 5 times, resulting in a remainder of 173.
Put 5 as the next digit of the answer. 
Result so far: 205.0
If we subtract 4495 from 4668, we get 173.
Include the next digit (0) from the dividend after 173, then repeat: 1730 / 899

Advancing to step 7:
899 goes into 1730 1 times with a remainder of 831.
Record the quotient 1 as the next digit in the result. 
Result so far: 2051.0
Deduct 899 from 1730 and we're left with 831.
Bring next digit (1) of the dividend behind the 831 and repeat the process: 8311 / 899

Let's proceed to step 8:
8311 divided by 899 is 9 with a remainder of 220.
The next digit of our result is 9. 
Result so far: 20519.0
Subtracting 8091 from 8311 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 9:
899 goes into 2200 2 times with a remainder of 402.
Use 2 as the next digit of our solution. 
Result so far: 20519.2
Subtracting 1798 from 2200 leaves us with 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Advancing to step 10:
If we divide 4020 by 899, we get 4 and a remainder of 424.
Put 4 as the next digit of the answer. 
Result so far: 20519.24
Subtracting 3596 from 4020 leaves us with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Step 11:
899 goes into 4240 4 times with a remainder of 644.
Put 4 as the next digit of the answer. 
Result so far: 20519.244
Subtract 3596 from 4240 to get 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

The final result is 20519.244 with a remainder of 0.0644.
