We look at the division of 450528 by 38 
The aim is to understand the frequency of 38 in 450528.

Step 1:
The number 38 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 38

On to step 2:
If we divide 45 by 38, we get 1 and a remainder of 7.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 38 from 45 to get 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 38

Step 3:
38 goes into 70 1 times with a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 11.0
The remainder is 32 after subtracting 38 from 70.
Append the next digit (5) from the dividend to 32 and continue with: 325 / 38

Let's proceed to step 4:
The number 38 fits into 325 8 times, leaving a remainder of 21.
Use 8 as the next digit of our solution. 
Result so far: 118.0
If we subtract 304 from 325, we get 21.
Take the next digit (2) from the dividend and append it to 21, then repeat: 212 / 38

Advancing to step 5:
When dividing 212 by 38, we get 5 with a remainder of 22.
Write down 5 as next digit of the result. 
Result so far: 1185.0
Subtract 190 from 212 to get 22.
Fetch the next digit (8) from the dividend, attach it to 22 and continue: 228 / 38

Moving on to step 6:
228 divided by 38 is 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 11856.0
If we subtract 228 from 228, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
The number 38 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 11856.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
The number 38 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 11856.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 11856.0 with a remaining 0.0.
