435457 ÷ 38 
The aim is to understand the frequency of 38 in 435457.

Step 1:
If we divide 4 by 38, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 38

Moving on to step 2:
The number 38 fits into 43 1 times, leaving a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 38 away from 43, we end up with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 38

On to step 3:
The number 38 fits into 55 1 times, leaving a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Deduct 38 from 55 and we're left with 17.
Fetch the next digit (4) from the dividend, attach it to 17 and continue: 174 / 38

Step 4:
If we divide 174 by 38, we get 4 and a remainder of 22.
Use 4 as the next digit of our solution. 
Result so far: 114.0
Deduct 152 from 174 and we're left with 22.
Include the next digit (5) from the dividend after 22, then repeat: 225 / 38

Advancing to step 5:
When dividing 225 by 38, we get 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 1145.0
The remainder is 35 after subtracting 190 from 225.
Bring next digit (7) of the dividend behind the 35 and repeat the process: 357 / 38

Moving on to step 6:
38 goes into 357 9 times with a remainder of 15.
The number 9 becomes the next digit in our result. 
Result so far: 11459.0
If we take 342 away from 357, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
If we divide 150 by 38, we get 3 and a remainder of 36.
The number 3 becomes the next digit in our result. 
Result so far: 11459.3
If we take 114 away from 150, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 8:
38 goes into 360 9 times with a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 11459.39
Subtract 342 from 360 to 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.

On to step 9:
The number 38 fits into 180 4 times, leaving a remainder of 28.
The next digit of our result is 4. 
Result so far: 11459.394
If we take 152 away from 180, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 10:
When dividing 280 by 38, we get 7 with a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 11459.3947
Deduct 266 from 280 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 11:
140 divided by 38 is 3 with a remainder of 26.
Record the quotient 3 as the next digit in the result. 
Result so far: 11459.39473
Deduct 114 from 140 and we're left with 26.
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 12:
38 can be fit into 260 6 times, resulting in a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 11459.394736
If we take 228 away from 260, we end up 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 13:
38 goes into 320 8 times with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 11459.3947368
Subtract 304 from 320 to get 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 14:
38 goes into 160 4 times with a remainder of 8.
The next digit of our result is 4. 
Result so far: 11459.39473684
If we take 152 away from 160, we end up 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.

The quotient of the division is 11459.39473684, and the remainder is 8e-09.
