Let's divide 72292928 by 437
The aim is to understand the frequency of 437 in 72292928.

Advancing to step 1:
When dividing 7 by 437, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 437

On to step 2:
The number 437 fits into 72 0 times, leaving a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Include the next digit (2) from the dividend after 72, then repeat: 722 / 437

On to step 3:
If we divide 722 by 437, we get 1 and a remainder of 285.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 437 from 722 and we're left with 285.
Include the next digit (9) from the dividend after 285, then repeat: 2859 / 437

Step 4:
When dividing 2859 by 437, we get 6 with a remainder of 237.
The next digit of our result is 6. 
Result so far: 16.0
Deduct 2622 from 2859 and we're left with 237.
Fetch the next digit (2) from the dividend, attach it to 237 and continue: 2372 / 437

Advancing to step 5:
If we divide 2372 by 437, we get 5 and a remainder of 187.
Write down 5 as next digit of the result. 
Result so far: 165.0
If we subtract 2185 from 2372, we get 187.
Bring next digit (9) of the dividend behind the 187 and repeat the process: 1879 / 437

Step 6:
437 goes into 1879 4 times with a remainder of 131.
Put 4 as the next digit of the answer. 
Result so far: 1654.0
Subtracting 1748 from 1879 leaves us with 131.
Append the next digit (2) from the dividend to 131 and continue with: 1312 / 437

Step 7:
When dividing 1312 by 437, we get 3 with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 16543.0
Deduct 1311 from 1312 and we're left with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 437

On to step 8:
The number 437 fits into 18 0 times, leaving a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 165430.0
If we subtract 0 from 18, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 9:
437 goes into 180 0 times with a remainder of 180.
The number 0 becomes the next digit in our result. 
Result so far: 165430.0
Subtract 0 from 180 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 10:
437 can be fit into 1800 4 times, resulting in a remainder of 52.
The next digit of our result is 4. 
Result so far: 165430.04
If we take 1748 away from 1800, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 11:
If we divide 520 by 437, we get 1 and a remainder of 83.
Put 1 as the next digit of the answer. 
Result so far: 165430.041
The remainder is 83 after subtracting 437 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Advancing to step 12:
The number 437 fits into 830 1 times, leaving a remainder of 393.
Write down 1 as next digit of the result. 
Result so far: 165430.0411
If we subtract 437 from 830, we get 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Our division results in 165430.0411 with a remaining 0.00393.
