Let's divide 18657038 by 437
The aim is to understand the frequency of 437 in 18657038.

Advancing to step 1:
The number 437 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 437

On to step 2:
If we divide 18 by 437, we get 0 and a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Include the next digit (6) from the dividend after 18, then repeat: 186 / 437

Advancing to step 3:
If we divide 186 by 437, we get 0 and a remainder of 186.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 186 and we're left with 186.
Grab the next digit (5) from the dividend, add it to 186, then carry on: 1865 / 437

Moving on to step 4:
1865 divided by 437 is 4 with a remainder of 117.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 1748 from 1865, we get 117.
Grab the next digit (7) from the dividend, add it to 117, then carry on: 1177 / 437

On to step 5:
If we divide 1177 by 437, we get 2 and a remainder of 303.
The next digit of our result is 2. 
Result so far: 42.0
Deduct 874 from 1177 and we're left with 303.
Append the next digit (0) from the dividend to 303 and continue with: 3030 / 437

Advancing to step 6:
437 goes into 3030 6 times with a remainder of 408.
Put 6 as the next digit of the answer. 
Result so far: 426.0
Subtracting 2622 from 3030 leaves us with 408.
Grab the next digit (3) from the dividend, add it to 408, then carry on: 4083 / 437

Going ahead to step 7:
When dividing 4083 by 437, we get 9 with a remainder of 150.
Record the quotient 9 as the next digit in the result. 
Result so far: 4269.0
The remainder is 150 after subtracting 3933 from 4083.
Grab the next digit (8) from the dividend, add it to 150, then carry on: 1508 / 437

Advancing to step 8:
The number 437 fits into 1508 3 times, leaving a remainder of 197.
The number 3 becomes the next digit in our result. 
Result so far: 42693.0
Subtract 1311 from 1508 to get 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Let's proceed to step 9:
When dividing 1970 by 437, we get 4 with a remainder of 222.
Write down 4 as next digit of the result. 
Result so far: 42693.4
Subtract 1748 from 1970 to get 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

On to step 10:
The number 437 fits into 2220 5 times, leaving a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 42693.45
If we subtract 2185 from 2220, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 11:
When dividing 350 by 437, we get 0 with a remainder of 350.
The number 0 becomes the next digit in our result. 
Result so far: 42693.45
Deduct 0 from 350 and we're left with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Moving on to step 12:
437 can be fit into 3500 8 times, resulting in a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 42693.4508
Deduct 3496 from 3500 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 13:
If we divide 40 by 437, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 42693.4508
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 14:
437 goes into 400 0 times with a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 42693.4508
Deduct 0 from 400 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

After the division, we end up with 42693.4508 and a remainder of 4e-05.
