Let's divide 55540745 by 38
The aim is to understand the frequency of 38 in 55540745.

Advancing to step 1:
38 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 38

On to step 2:
When dividing 55 by 38, we get 1 with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 38 from 55 and we're left with 17.
Take the next digit (5) from the dividend and append it to 17, then repeat: 175 / 38

Step 3:
175 divided by 38 is 4 with a remainder of 23.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtracting 152 from 175 leaves us with 23.
Include the next digit (4) from the dividend after 23, then repeat: 234 / 38

Moving on to step 4:
38 goes into 234 6 times with a remainder of 6.
The next digit of our result is 6. 
Result so far: 146.0
Subtracting 228 from 234 leaves us with 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 38

Advancing to step 5:
When dividing 60 by 38, we get 1 with a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 1461.0
If we take 38 away from 60, we end up with 22.
Take the next digit (7) from the dividend and append it to 22, then repeat: 227 / 38

Going ahead to step 6:
The number 38 fits into 227 5 times, leaving a remainder of 37.
The next digit of our result is 5. 
Result so far: 14615.0
Subtracting 190 from 227 leaves us with 37.
Fetch the next digit (4) from the dividend, attach it to 37 and continue: 374 / 38

Let's proceed to step 7:
If we divide 374 by 38, we get 9 and a remainder of 32.
The next digit of our result is 9. 
Result so far: 146159.0
The remainder is 32 after subtracting 342 from 374.
Fetch the next digit (5) from the dividend, attach it to 32 and continue: 325 / 38

Step 8:
If we divide 325 by 38, we get 8 and a remainder of 21.
Write down 8 as next digit of the result. 
Result so far: 1461598.0
Deduct 304 from 325 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 9:
38 goes into 210 5 times with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 1461598.5
Deduct 190 from 210 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 10:
When dividing 200 by 38, we get 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 1461598.55
Subtract 190 from 200 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 1461598.55 and a remainder of 0.01.
