44023712 divided by 999 
The aim is to understand the frequency of 999 in 44023712.

Step 1:
999 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 999

Advancing to step 2:
999 goes into 44 0 times with a remainder of 44.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 44, we get 44.
Take the next digit (0) from the dividend and append it to 44, then repeat: 440 / 999

Advancing to step 3:
If we divide 440 by 999, we get 0 and a remainder of 440.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 440, we get 440.
Include the next digit (2) from the dividend after 440, then repeat: 4402 / 999

Step 4:
The number 999 fits into 4402 4 times, leaving a remainder of 406.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 3996 from 4402 and we're left with 406.
Bring next digit (3) of the dividend behind the 406 and repeat the process: 4063 / 999

Going ahead to step 5:
999 can be fit into 4063 4 times, resulting in a remainder of 67.
The number 4 becomes the next digit in our result. 
Result so far: 44.0
The remainder is 67 after subtracting 3996 from 4063.
Grab the next digit (7) from the dividend, add it to 67, then carry on: 677 / 999

Advancing to step 6:
When dividing 677 by 999, we get 0 with a remainder of 677.
Write down 0 as next digit of the result. 
Result so far: 440.0
If we subtract 0 from 677, we get 677.
Fetch the next digit (1) from the dividend, attach it to 677 and continue: 6771 / 999

On to step 7:
999 goes into 6771 6 times with a remainder of 777.
Put 6 as the next digit of the answer. 
Result so far: 4406.0
Subtracting 5994 from 6771 leaves us with 777.
Fetch the next digit (2) from the dividend, attach it to 777 and continue: 7772 / 999

Advancing to step 8:
7772 divided by 999 is 7 with a remainder of 779.
Write down 7 as next digit of the result. 
Result so far: 44067.0
If we take 6993 away from 7772, we end up with 779.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7790, and continue the process.

Advancing to step 9:
999 goes into 7790 7 times with a remainder of 797.
Put 7 as the next digit of the answer. 
Result so far: 44067.7
If we subtract 6993 from 7790, we get 797.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7970, and continue the process.

Let's proceed to step 10:
999 can be fit into 7970 7 times, resulting in a remainder of 977.
Record the quotient 7 as the next digit in the result. 
Result so far: 44067.77
Subtracting 6993 from 7970 leaves us with 977.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9770, and continue the process.

Our division results in 44067.77 with a remaining 0.977.
