We look at the division of 52453375 by 938 
The aim is to understand the frequency of 938 in 52453375.

Step 1:
938 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
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 / 938

Going ahead to step 2:
The number 938 fits into 52 0 times, leaving a remainder of 52.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 52 to get 52.
Grab the next digit (4) from the dividend, add it to 52, then carry on: 524 / 938

Advancing to step 3:
938 can be fit into 524 0 times, resulting in a remainder of 524.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 524, we end up with 524.
Take the next digit (5) from the dividend and append it to 524, then repeat: 5245 / 938

Moving on to step 4:
When dividing 5245 by 938, we get 5 with a remainder of 555.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 4690 from 5245 and we're left with 555.
Fetch the next digit (3) from the dividend, attach it to 555 and continue: 5553 / 938

Step 5:
When dividing 5553 by 938, we get 5 with a remainder of 863.
The number 5 becomes the next digit in our result. 
Result so far: 55.0
If we take 4690 away from 5553, we end up with 863.
Fetch the next digit (3) from the dividend, attach it to 863 and continue: 8633 / 938

Step 6:
When dividing 8633 by 938, we get 9 with a remainder of 191.
The next digit of our result is 9. 
Result so far: 559.0
Subtracting 8442 from 8633 leaves us with 191.
Append the next digit (7) from the dividend to 191 and continue with: 1917 / 938

Step 7:
The number 938 fits into 1917 2 times, leaving a remainder of 41.
The next digit of our result is 2. 
Result so far: 5592.0
Deduct 1876 from 1917 and we're left with 41.
Bring next digit (5) of the dividend behind the 41 and repeat the process: 415 / 938

On to step 8:
When dividing 415 by 938, we get 0 with a remainder of 415.
Put 0 as the next digit of the answer. 
Result so far: 55920.0
The remainder is 415 after subtracting 0 from 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Moving on to step 9:
938 can be fit into 4150 4 times, resulting in a remainder of 398.
Write down 4 as next digit of the result. 
Result so far: 55920.4
Deduct 3752 from 4150 and we're left with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Advancing to step 10:
3980 divided by 938 is 4 with a remainder of 228.
Record the quotient 4 as the next digit in the result. 
Result so far: 55920.44
If we take 3752 away from 3980, we end up with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

The final result is 55920.44 with a remainder of 0.228.
