We look at the division of 42752 by 78 
The aim is to understand the frequency of 78 in 42752.

Moving on to step 1:
78 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 78

Moving on to step 2:
When dividing 42 by 78, we get 0 with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Bring next digit (7) of the dividend behind the 42 and repeat the process: 427 / 78

Advancing to step 3:
78 can be fit into 427 5 times, resulting in a remainder of 37.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 37 after subtracting 390 from 427.
Bring next digit (5) of the dividend behind the 37 and repeat the process: 375 / 78

Going ahead to step 4:
When dividing 375 by 78, we get 4 with a remainder of 63.
Use 4 as the next digit of our solution. 
Result so far: 54.0
If we take 312 away from 375, we end up with 63.
Fetch the next digit (2) from the dividend, attach it to 63 and continue: 632 / 78

Step 5:
632 divided by 78 is 8 with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 548.0
The remainder is 8 after subtracting 624 from 632.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 6:
If we divide 80 by 78, we get 1 and a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 548.1
If we take 78 away from 80, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
20 divided by 78 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 548.1
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
78 goes into 200 2 times with a remainder of 44.
Write down 2 as next digit of the result. 
Result so far: 548.102
Subtract 156 from 200 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 9:
78 can be fit into 440 5 times, resulting in a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 548.1025
If we take 390 away from 440, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 10:
If we divide 500 by 78, we get 6 and a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 548.10256
If we take 468 away from 500, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 11:
When dividing 320 by 78, we get 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 548.102564
The remainder is 8 after subtracting 312 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 12:
78 goes into 80 1 times with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 548.1025641
The remainder is 2 after subtracting 78 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 13:
The number 78 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 548.1025641
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 548.1025641 and a remainder of 2e-08.
