We divide 22864190 by 999
The aim is to understand the frequency of 999 in 22864190.

Advancing to step 1:
When dividing 2 by 999, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 999

Moving on to step 2:
999 can be fit into 22 0 times, resulting in a remainder of 22.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 22 leaves us with 22.
Append the next digit (8) from the dividend to 22 and continue with: 228 / 999

On to step 3:
228 divided by 999 is 0 with a remainder of 228.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 228, we get 228.
Grab the next digit (6) from the dividend, add it to 228, then carry on: 2286 / 999

Going ahead to step 4:
If we divide 2286 by 999, we get 2 and a remainder of 288.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 1998 from 2286, we get 288.
Fetch the next digit (4) from the dividend, attach it to 288 and continue: 2884 / 999

Going ahead to step 5:
If we divide 2884 by 999, we get 2 and a remainder of 886.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
If we take 1998 away from 2884, we end up with 886.
Take the next digit (1) from the dividend and append it to 886, then repeat: 8861 / 999

Step 6:
If we divide 8861 by 999, we get 8 and a remainder of 869.
The number 8 becomes the next digit in our result. 
Result so far: 228.0
Subtracting 7992 from 8861 leaves us with 869.
Take the next digit (9) from the dividend and append it to 869, then repeat: 8699 / 999

Advancing to step 7:
999 goes into 8699 8 times with a remainder of 707.
Put 8 as the next digit of the answer. 
Result so far: 2288.0
Deduct 7992 from 8699 and we're left with 707.
Take the next digit (0) from the dividend and append it to 707, then repeat: 7070 / 999

Going ahead to step 8:
The number 999 fits into 7070 7 times, leaving a remainder of 77.
The next digit of our result is 7. 
Result so far: 22887.0
Deduct 6993 from 7070 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Advancing to step 9:
999 can be fit into 770 0 times, resulting in a remainder of 770.
The number 0 becomes the next digit in our result. 
Result so far: 22887.0
The remainder is 770 after subtracting 0 from 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7700, and continue the process.

Let's proceed to step 10:
The number 999 fits into 7700 7 times, leaving a remainder of 707.
Put 7 as the next digit of the answer. 
Result so far: 22887.07
Subtract 6993 from 7700 to get 707.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7070, and continue the process.

Advancing to step 11:
999 goes into 7070 7 times with a remainder of 77.
Record the quotient 7 as the next digit in the result. 
Result so far: 22887.077
Subtracting 6993 from 7070 leaves us with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

The final outcome is 22887.077, with a leftover of 0.0077.
