331264 ÷ 78 
The aim is to understand the frequency of 78 in 331264.

Moving on to step 1:
3 divided by 78 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 78

Let's proceed to step 2:
The number 78 fits into 33 0 times, leaving a remainder of 33.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 33 leaves us with 33.
Include the next digit (1) from the dividend after 33, then repeat: 331 / 78

Advancing to step 3:
If we divide 331 by 78, we get 4 and a remainder of 19.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 19 after subtracting 312 from 331.
Append the next digit (2) from the dividend to 19 and continue with: 192 / 78

Step 4:
78 can be fit into 192 2 times, resulting in a remainder of 36.
The next digit of our result is 2. 
Result so far: 42.0
Deduct 156 from 192 and we're left with 36.
Append the next digit (6) from the dividend to 36 and continue with: 366 / 78

Moving on to step 5:
If we divide 366 by 78, we get 4 and a remainder of 54.
The number 4 becomes the next digit in our result. 
Result so far: 424.0
If we subtract 312 from 366, we get 54.
Fetch the next digit (4) from the dividend, attach it to 54 and continue: 544 / 78

Advancing to step 6:
If we divide 544 by 78, we get 6 and a remainder of 76.
Write down 6 as next digit of the result. 
Result so far: 4246.0
The remainder is 76 after subtracting 468 from 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 7:
760 divided by 78 is 9 with a remainder of 58.
Use 9 as the next digit of our solution. 
Result so far: 4246.9
Deduct 702 from 760 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 8:
78 goes into 580 7 times with a remainder of 34.
Write down 7 as next digit of the result. 
Result so far: 4246.97
Subtracting 546 from 580 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 9:
78 goes into 340 4 times with a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 4246.974
Subtracting 312 from 340 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 10:
If we divide 280 by 78, we get 3 and a remainder of 46.
The number 3 becomes the next digit in our result. 
Result so far: 4246.9743
If we take 234 away from 280, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 11:
78 goes into 460 5 times with a remainder of 70.
The next digit of our result is 5. 
Result so far: 4246.97435
Subtract 390 from 460 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 12:
78 goes into 700 8 times with a remainder of 76.
Use 8 as the next digit of our solution. 
Result so far: 4246.974358
Subtracting 624 from 700 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 13:
If we divide 760 by 78, we get 9 and a remainder of 58.
Put 9 as the next digit of the answer. 
Result so far: 4246.9743589
Deduct 702 from 760 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 14:
If we divide 580 by 78, we get 7 and a remainder of 34.
The next digit of our result is 7. 
Result so far: 4246.97435897
If we subtract 546 from 580, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final outcome is 4246.97435897, with a leftover of 3.4e-08.
