57378 ÷ 52 
The aim is to understand the frequency of 52 in 57378.

Going ahead to step 1:
5 divided by 52 is 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 52

On to step 2:
When dividing 57 by 52, we get 1 with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 52 from 57 and we're left with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 52

Let's proceed to step 3:
The number 52 fits into 53 1 times, leaving a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtracting 52 from 53 leaves us with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 52

Moving on to step 4:
17 divided by 52 is 0 with a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 110.0
The remainder is 17 after subtracting 0 from 17.
Append the next digit (8) from the dividend to 17 and continue with: 178 / 52

Let's proceed to step 5:
52 goes into 178 3 times with a remainder of 22.
The next digit of our result is 3. 
Result so far: 1103.0
If we take 156 away from 178, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 6:
52 goes into 220 4 times with a remainder of 12.
The next digit of our result is 4. 
Result so far: 1103.4
Subtract 208 from 220 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 7:
52 goes into 120 2 times with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 1103.42
The remainder is 16 after subtracting 104 from 120.
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 8:
52 can be fit into 160 3 times, resulting in a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 1103.423
The remainder is 4 after subtracting 156 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
40 divided by 52 is 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 1103.423
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 10:
400 divided by 52 is 7 with a remainder of 36.
Record the quotient 7 as the next digit in the result. 
Result so far: 1103.42307
The remainder is 36 after subtracting 364 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 11:
52 goes into 360 6 times with a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 1103.423076
Deduct 312 from 360 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 12:
52 goes into 480 9 times with a remainder of 12.
Record the quotient 9 as the next digit in the result. 
Result so far: 1103.4230769
Deduct 468 from 480 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 13:
If we divide 120 by 52, we get 2 and a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 1103.42307692
Subtract 104 from 120 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.

Our division results in 1103.42307692 with a remaining 1.6e-08.
