520980 divided by 38 
The aim is to understand the frequency of 38 in 520980.

Step 1:
If we divide 5 by 38, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 38

Moving on to step 2:
38 can be fit into 52 1 times, resulting in a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 38 from 52, we get 14.
Fetch the next digit (0) from the dividend, attach it to 14 and continue: 140 / 38

Step 3:
38 goes into 140 3 times with a remainder of 26.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
The remainder is 26 after subtracting 114 from 140.
Include the next digit (9) from the dividend after 26, then repeat: 269 / 38

Moving on to step 4:
If we divide 269 by 38, we get 7 and a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 137.0
Deduct 266 from 269 and we're left with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 38

Going ahead to step 5:
38 goes into 38 1 times with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1371.0
Subtracting 38 from 38 leaves us with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 38

Advancing to step 6:
38 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 13710.0
Subtract 0 from 0 to 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:
38 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 13710.0
Deduct 0 from 0 and we're left 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.

Going ahead to step 8:
38 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 13710.0
Deduct 0 from 0 and we're left 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.

After the division, we end up with 13710.0 and a remainder of 0.0.
