9274973 ÷ 999 
The aim is to understand the frequency of 999 in 9274973.

Moving on to step 1:
If we divide 9 by 999, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (2) from the dividend and append it to 9, then repeat: 92 / 999

On to step 2:
If we divide 92 by 999, we get 0 and a remainder of 92.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 92 to get 92.
Append the next digit (7) from the dividend to 92 and continue with: 927 / 999

Moving on to step 3:
927 divided by 999 is 0 with a remainder of 927.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 927 leaves us with 927.
Grab the next digit (4) from the dividend, add it to 927, then carry on: 9274 / 999

Advancing to step 4:
If we divide 9274 by 999, we get 9 and a remainder of 283.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 8991 from 9274 and we're left with 283.
Include the next digit (9) from the dividend after 283, then repeat: 2839 / 999

Going ahead to step 5:
999 goes into 2839 2 times with a remainder of 841.
Record the quotient 2 as the next digit in the result. 
Result so far: 92.0
Subtract 1998 from 2839 to get 841.
Append the next digit (7) from the dividend to 841 and continue with: 8417 / 999

Step 6:
If we divide 8417 by 999, we get 8 and a remainder of 425.
Put 8 as the next digit of the answer. 
Result so far: 928.0
If we subtract 7992 from 8417, we get 425.
Take the next digit (3) from the dividend and append it to 425, then repeat: 4253 / 999

Moving on to step 7:
When dividing 4253 by 999, we get 4 with a remainder of 257.
Put 4 as the next digit of the answer. 
Result so far: 9284.0
If we subtract 3996 from 4253, we get 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Advancing to step 8:
999 can be fit into 2570 2 times, resulting in a remainder of 572.
Use 2 as the next digit of our solution. 
Result so far: 9284.2
Subtract 1998 from 2570 to get 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

On to step 9:
5720 divided by 999 is 5 with a remainder of 725.
The number 5 becomes the next digit in our result. 
Result so far: 9284.25
Deduct 4995 from 5720 and we're left with 725.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7250, and continue the process.

Step 10:
999 can be fit into 7250 7 times, resulting in a remainder of 257.
Write down 7 as next digit of the result. 
Result so far: 9284.257
Deduct 6993 from 7250 and we're left with 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Let's proceed to step 11:
The number 999 fits into 2570 2 times, leaving a remainder of 572.
Put 2 as the next digit of the answer. 
Result so far: 9284.2572
Subtracting 1998 from 2570 leaves us with 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

Going ahead to step 12:
999 can be fit into 5720 5 times, resulting in a remainder of 725.
The next digit of our result is 5. 
Result so far: 9284.25725
Deduct 4995 from 5720 and we're left with 725.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7250, and continue the process.

Going ahead to step 13:
999 can be fit into 7250 7 times, resulting in a remainder of 257.
Record the quotient 7 as the next digit in the result. 
Result so far: 9284.257257
If we take 6993 away from 7250, we end up with 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

Going ahead to step 14:
999 can be fit into 2570 2 times, resulting in a remainder of 572.
Write down 2 as next digit of the result. 
Result so far: 9284.2572572
Deduct 1998 from 2570 and we're left with 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

Step 15:
When dividing 5720 by 999, we get 5 with a remainder of 725.
The next digit of our result is 5. 
Result so far: 9284.25725725
If we subtract 4995 from 5720, we get 725.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7250, and continue the process.

After the division, we end up with 9284.25725725 and a remainder of 7.25e-07.
