We divide 320975 by 78
The aim is to understand the frequency of 78 in 320975.

Moving on to step 1:
78 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 78

Going ahead to step 2:
The number 78 fits into 32 0 times, leaving a remainder of 32.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 32 leaves us with 32.
Append the next digit (0) from the dividend to 32 and continue with: 320 / 78

Advancing to step 3:
78 goes into 320 4 times with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 312 from 320, we get 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 78

Moving on to step 4:
If we divide 89 by 78, we get 1 and a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 41.0
Subtracting 78 from 89 leaves us with 11.
Take the next digit (7) from the dividend and append it to 11, then repeat: 117 / 78

Moving on to step 5:
78 goes into 117 1 times with a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 411.0
If we take 78 away from 117, we end up with 39.
Fetch the next digit (5) from the dividend, attach it to 39 and continue: 395 / 78

Advancing to step 6:
The number 78 fits into 395 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 4115.0
The remainder is 5 after subtracting 390 from 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
50 divided by 78 is 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 4115.0
If we subtract 0 from 50, we get 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 goes into 500 6 times with a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 4115.06
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.

On to step 9:
78 goes into 320 4 times with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 4115.064
Subtract 312 from 320 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
The number 78 fits into 80 1 times, leaving a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 4115.0641
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.

Step 11:
78 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 4115.0641
If we take 0 away from 20, we end up 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.

Advancing to step 12:
If we divide 200 by 78, we get 2 and a remainder of 44.
Write down 2 as next digit of the result. 
Result so far: 4115.064102
Deduct 156 from 200 and we're left 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.

Advancing to step 13:
78 goes into 440 5 times with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 4115.0641025
Subtract 390 from 440 to get 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 14:
78 goes into 500 6 times with a remainder of 32.
The next digit of our result is 6. 
Result so far: 4115.06410256
Deduct 468 from 500 and we're left 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.

The final result is 4115.06410256 with a remainder of 3.2e-08.
