30172311 divided by 437 
The aim is to understand the frequency of 437 in 30172311.

Let's proceed to step 1:
437 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 437

Moving on to step 2:
If we divide 30 by 437, we get 0 and a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Bring next digit (1) of the dividend behind the 30 and repeat the process: 301 / 437

Moving on to step 3:
The number 437 fits into 301 0 times, leaving a remainder of 301.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 301 after subtracting 0 from 301.
Bring next digit (7) of the dividend behind the 301 and repeat the process: 3017 / 437

Going ahead to step 4:
If we divide 3017 by 437, we get 6 and a remainder of 395.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 395 after subtracting 2622 from 3017.
Append the next digit (2) from the dividend to 395 and continue with: 3952 / 437

On to step 5:
If we divide 3952 by 437, we get 9 and a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 69.0
Subtracting 3933 from 3952 leaves us with 19.
Include the next digit (3) from the dividend after 19, then repeat: 193 / 437

Let's proceed to step 6:
The number 437 fits into 193 0 times, leaving a remainder of 193.
Put 0 as the next digit of the answer. 
Result so far: 690.0
Deduct 0 from 193 and we're left with 193.
Grab the next digit (1) from the dividend, add it to 193, then carry on: 1931 / 437

On to step 7:
437 goes into 1931 4 times with a remainder of 183.
Record the quotient 4 as the next digit in the result. 
Result so far: 6904.0
Subtract 1748 from 1931 to get 183.
Include the next digit (1) from the dividend after 183, then repeat: 1831 / 437

On to step 8:
If we divide 1831 by 437, we get 4 and a remainder of 83.
Record the quotient 4 as the next digit in the result. 
Result so far: 69044.0
Subtract 1748 from 1831 to get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Going ahead to step 9:
830 divided by 437 is 1 with a remainder of 393.
The next digit of our result is 1. 
Result so far: 69044.1
Subtracting 437 from 830 leaves us with 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Moving on to step 10:
437 goes into 3930 8 times with a remainder of 434.
The next digit of our result is 8. 
Result so far: 69044.18
Subtract 3496 from 3930 to get 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Step 11:
437 goes into 4340 9 times with a remainder of 407.
The next digit of our result is 9. 
Result so far: 69044.189
The remainder is 407 after subtracting 3933 from 4340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

Step 12:
When dividing 4070 by 437, we get 9 with a remainder of 137.
The number 9 becomes the next digit in our result. 
Result so far: 69044.1899
Subtracting 3933 from 4070 leaves us with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

The quotient of the division is 69044.1899, and the remainder is 0.00137.
