Let's divide 272342 by 78
The aim is to understand the frequency of 78 in 272342.

On to step 1:
If we divide 2 by 78, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 78

Step 2:
The number 78 fits into 27 0 times, leaving a remainder of 27.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 27, we end up with 27.
Grab the next digit (2) from the dividend, add it to 27, then carry on: 272 / 78

Going ahead to step 3:
The number 78 fits into 272 3 times, leaving a remainder of 38.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 234 from 272 and we're left with 38.
Take the next digit (3) from the dividend and append it to 38, then repeat: 383 / 78

Advancing to step 4:
78 can be fit into 383 4 times, resulting in a remainder of 71.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
Subtract 312 from 383 to get 71.
Grab the next digit (4) from the dividend, add it to 71, then carry on: 714 / 78

Moving on to step 5:
78 can be fit into 714 9 times, resulting in a remainder of 12.
Record the quotient 9 as the next digit in the result. 
Result so far: 349.0
Deduct 702 from 714 and we're left with 12.
Grab the next digit (2) from the dividend, add it to 12, then carry on: 122 / 78

On to step 6:
If we divide 122 by 78, we get 1 and a remainder of 44.
Write down 1 as next digit of the result. 
Result so far: 3491.0
If we subtract 78 from 122, we 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.

Moving on to step 7:
If we divide 440 by 78, we get 5 and a remainder of 50.
The next digit of our result is 5. 
Result so far: 3491.5
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.

Let's proceed to step 8:
78 can be fit into 500 6 times, resulting in a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 3491.56
Subtracting 468 from 500 leaves us 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.

Step 9:
When dividing 320 by 78, we get 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 3491.564
Deduct 312 from 320 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
78 can be fit into 80 1 times, resulting in a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 3491.5641
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.

Step 11:
78 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 3491.5641
Subtracting 0 from 20 leaves us 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.

Let's proceed to step 12:
The number 78 fits into 200 2 times, leaving a remainder of 44.
Use 2 as the next digit of our solution. 
Result so far: 3491.564102
Subtracting 156 from 200 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 13:
When dividing 440 by 78, we get 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 3491.5641025
The remainder is 50 after subtracting 390 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 14:
78 can be fit into 500 6 times, resulting in a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 3491.56410256
The remainder is 32 after subtracting 468 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 3491.56410256, with a leftover of 3.2e-08.
