We're dividing 40912856 by 999 
The aim is to understand the frequency of 999 in 40912856.

Advancing to step 1:
999 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 999

Let's proceed to step 2:
If we divide 40 by 999, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Append the next digit (9) from the dividend to 40 and continue with: 409 / 999

Let's proceed to step 3:
409 divided by 999 is 0 with a remainder of 409.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 409 to get 409.
Fetch the next digit (1) from the dividend, attach it to 409 and continue: 4091 / 999

Step 4:
The number 999 fits into 4091 4 times, leaving a remainder of 95.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 3996 away from 4091, we end up with 95.
Include the next digit (2) from the dividend after 95, then repeat: 952 / 999

Advancing to step 5:
999 goes into 952 0 times with a remainder of 952.
The next digit of our result is 0. 
Result so far: 40.0
Subtracting 0 from 952 leaves us with 952.
Include the next digit (8) from the dividend after 952, then repeat: 9528 / 999

Moving on to step 6:
The number 999 fits into 9528 9 times, leaving a remainder of 537.
The number 9 becomes the next digit in our result. 
Result so far: 409.0
Subtracting 8991 from 9528 leaves us with 537.
Grab the next digit (5) from the dividend, add it to 537, then carry on: 5375 / 999

Let's proceed to step 7:
999 goes into 5375 5 times with a remainder of 380.
Use 5 as the next digit of our solution. 
Result so far: 4095.0
If we subtract 4995 from 5375, we get 380.
Append the next digit (6) from the dividend to 380 and continue with: 3806 / 999

On to step 8:
3806 divided by 999 is 3 with a remainder of 809.
The number 3 becomes the next digit in our result. 
Result so far: 40953.0
Subtracting 2997 from 3806 leaves us with 809.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8090, and continue the process.

Let's proceed to step 9:
If we divide 8090 by 999, we get 8 and a remainder of 98.
Use 8 as the next digit of our solution. 
Result so far: 40953.8
Deduct 7992 from 8090 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Going ahead to step 10:
999 can be fit into 980 0 times, resulting in a remainder of 980.
The next digit of our result is 0. 
Result so far: 40953.8
Subtract 0 from 980 to get 980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9800, and continue the process.

On to step 11:
The number 999 fits into 9800 9 times, leaving a remainder of 809.
Put 9 as the next digit of the answer. 
Result so far: 40953.809
The remainder is 809 after subtracting 8991 from 9800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8090, and continue the process.

Step 12:
If we divide 8090 by 999, we get 8 and a remainder of 98.
Write down 8 as next digit of the result. 
Result so far: 40953.8098
Subtracting 7992 from 8090 leaves us with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

On to step 13:
980 divided by 999 is 0 with a remainder of 980.
The number 0 becomes the next digit in our result. 
Result so far: 40953.8098
Deduct 0 from 980 and we're left with 980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9800, and continue the process.

Advancing to step 14:
If we divide 9800 by 999, we get 9 and a remainder of 809.
Use 9 as the next digit of our solution. 
Result so far: 40953.809809
The remainder is 809 after subtracting 8991 from 9800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8090, and continue the process.

Let's proceed to step 15:
999 can be fit into 8090 8 times, resulting in a remainder of 98.
Use 8 as the next digit of our solution. 
Result so far: 40953.8098098
If we subtract 7992 from 8090, we get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Going ahead to step 16:
The number 999 fits into 980 0 times, leaving a remainder of 980.
The next digit of our result is 0. 
Result so far: 40953.8098098
Deduct 0 from 980 and we're left with 980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9800, and continue the process.

After the division, we end up with 40953.8098098 and a remainder of 9.8e-07.
