23972003 ÷ 909 
The aim is to understand the frequency of 909 in 23972003.

Advancing to step 1:
When dividing 2 by 909, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 909

On to step 2:
If we divide 23 by 909, we get 0 and a remainder of 23.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 23 to get 23.
Bring next digit (9) of the dividend behind the 23 and repeat the process: 239 / 909

Step 3:
The number 909 fits into 239 0 times, leaving a remainder of 239.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 239 and we're left with 239.
Include the next digit (7) from the dividend after 239, then repeat: 2397 / 909

Going ahead to step 4:
If we divide 2397 by 909, we get 2 and a remainder of 579.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 1818 from 2397 to get 579.
Bring next digit (2) of the dividend behind the 579 and repeat the process: 5792 / 909

Going ahead to step 5:
When dividing 5792 by 909, we get 6 with a remainder of 338.
Put 6 as the next digit of the answer. 
Result so far: 26.0
If we subtract 5454 from 5792, we get 338.
Bring next digit (0) of the dividend behind the 338 and repeat the process: 3380 / 909

Moving on to step 6:
When dividing 3380 by 909, we get 3 with a remainder of 653.
Put 3 as the next digit of the answer. 
Result so far: 263.0
Subtract 2727 from 3380 to get 653.
Append the next digit (0) from the dividend to 653 and continue with: 6530 / 909

Going ahead to step 7:
909 goes into 6530 7 times with a remainder of 167.
Write down 7 as next digit of the result. 
Result so far: 2637.0
Deduct 6363 from 6530 and we're left with 167.
Append the next digit (3) from the dividend to 167 and continue with: 1673 / 909

Let's proceed to step 8:
909 goes into 1673 1 times with a remainder of 764.
Record the quotient 1 as the next digit in the result. 
Result so far: 26371.0
Deduct 909 from 1673 and we're left with 764.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7640, and continue the process.

On to step 9:
When dividing 7640 by 909, we get 8 with a remainder of 368.
Put 8 as the next digit of the answer. 
Result so far: 26371.8
Subtract 7272 from 7640 to get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Let's proceed to step 10:
When dividing 3680 by 909, we get 4 with a remainder of 44.
Put 4 as the next digit of the answer. 
Result so far: 26371.84
If we take 3636 away from 3680, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 11:
909 goes into 440 0 times with a remainder of 440.
The number 0 becomes the next digit in our result. 
Result so far: 26371.84
Deduct 0 from 440 and we're left with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Step 12:
When dividing 4400 by 909, we get 4 with a remainder of 764.
The number 4 becomes the next digit in our result. 
Result so far: 26371.8404
Subtract 3636 from 4400 to get 764.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7640, and continue the process.

Let's proceed to step 13:
The number 909 fits into 7640 8 times, leaving a remainder of 368.
The next digit of our result is 8. 
Result so far: 26371.84048
If we subtract 7272 from 7640, we get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Let's proceed to step 14:
If we divide 3680 by 909, we get 4 and a remainder of 44.
The number 4 becomes the next digit in our result. 
Result so far: 26371.840484
The remainder is 44 after subtracting 3636 from 3680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 15:
When dividing 440 by 909, we get 0 with a remainder of 440.
Use 0 as the next digit of our solution. 
Result so far: 26371.840484
If we take 0 away from 440, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Going ahead to step 16:
909 goes into 4400 4 times with a remainder of 764.
The number 4 becomes the next digit in our result. 
Result so far: 26371.84048404
If we subtract 3636 from 4400, we get 764.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7640, and continue the process.

In conclusion, the division gives 26371.84048404 with a balance of 7.64e-07.
