15651 ÷ 38 
The aim is to understand the frequency of 38 in 15651.

Going ahead to step 1:
The number 38 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 38

Let's proceed to step 2:
The number 38 fits into 15 0 times, leaving a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Bring next digit (6) of the dividend behind the 15 and repeat the process: 156 / 38

Advancing to step 3:
If we divide 156 by 38, we get 4 and a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 4 after subtracting 152 from 156.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 38

On to step 4:
When dividing 45 by 38, we get 1 with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 41.0
If we take 38 away from 45, we end up with 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 38

Advancing to step 5:
71 divided by 38 is 1 with a remainder of 33.
Put 1 as the next digit of the answer. 
Result so far: 411.0
Deduct 38 from 71 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Going ahead to step 6:
38 goes into 330 8 times with a remainder of 26.
The number 8 becomes the next digit in our result. 
Result so far: 411.8
The remainder is 26 after subtracting 304 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 7:
If we divide 260 by 38, we get 6 and a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 411.86
Deduct 228 from 260 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 8:
38 can be fit into 320 8 times, resulting in a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 411.868
Subtracting 304 from 320 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 9:
When dividing 160 by 38, we get 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 411.8684
Subtracting 152 from 160 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
The number 38 fits into 80 2 times, leaving a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 411.86842
Subtract 76 from 80 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 11:
40 divided by 38 is 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 411.868421
The remainder is 2 after subtracting 38 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 12:
When dividing 20 by 38, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 411.868421
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 13:
38 can be fit into 200 5 times, resulting in a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 411.86842105
Subtracting 190 from 200 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 411.86842105 with a remainder of 1e-08.
