We divide 15156745 by 437
The aim is to understand the frequency of 437 in 15156745.

Step 1:
1 divided by 437 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 437

Step 2:
437 goes into 15 0 times with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Take the next digit (1) from the dividend and append it to 15, then repeat: 151 / 437

Moving on to step 3:
If we divide 151 by 437, we get 0 and a remainder of 151.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 151, we get 151.
Append the next digit (5) from the dividend to 151 and continue with: 1515 / 437

Going ahead to step 4:
1515 divided by 437 is 3 with a remainder of 204.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 1311 from 1515 leaves us with 204.
Take the next digit (6) from the dividend and append it to 204, then repeat: 2046 / 437

Going ahead to step 5:
437 goes into 2046 4 times with a remainder of 298.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
Subtract 1748 from 2046 to get 298.
Include the next digit (7) from the dividend after 298, then repeat: 2987 / 437

On to step 6:
If we divide 2987 by 437, we get 6 and a remainder of 365.
Use 6 as the next digit of our solution. 
Result so far: 346.0
Deduct 2622 from 2987 and we're left with 365.
Grab the next digit (4) from the dividend, add it to 365, then carry on: 3654 / 437

Advancing to step 7:
If we divide 3654 by 437, we get 8 and a remainder of 158.
Use 8 as the next digit of our solution. 
Result so far: 3468.0
Subtract 3496 from 3654 to get 158.
Bring next digit (5) of the dividend behind the 158 and repeat the process: 1585 / 437

Let's proceed to step 8:
437 can be fit into 1585 3 times, resulting in a remainder of 274.
The number 3 becomes the next digit in our result. 
Result so far: 34683.0
If we take 1311 away from 1585, we end up with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Let's proceed to step 9:
2740 divided by 437 is 6 with a remainder of 118.
Use 6 as the next digit of our solution. 
Result so far: 34683.6
If we take 2622 away from 2740, we end up with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Advancing to step 10:
If we divide 1180 by 437, we get 2 and a remainder of 306.
Record the quotient 2 as the next digit in the result. 
Result so far: 34683.62
Deduct 874 from 1180 and we're left with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

On to step 11:
If we divide 3060 by 437, we get 7 and a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 34683.627
Deduct 3059 from 3060 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 12:
If we divide 10 by 437, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 34683.627
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 13:
When dividing 100 by 437, we get 0 with a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 34683.627
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

After the division, we end up with 34683.627 and a remainder of 0.0001.
