966972 divided by 78 
The aim is to understand the frequency of 78 in 966972.

Moving on to step 1:
78 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 78

Step 2:
78 can be fit into 96 1 times, resulting in a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 78 from 96 leaves us with 18.
Include the next digit (6) from the dividend after 18, then repeat: 186 / 78

Let's proceed to step 3:
186 divided by 78 is 2 with a remainder of 30.
The next digit of our result is 2. 
Result so far: 12.0
The remainder is 30 after subtracting 156 from 186.
Include the next digit (9) from the dividend after 30, then repeat: 309 / 78

Let's proceed to step 4:
78 goes into 309 3 times with a remainder of 75.
The number 3 becomes the next digit in our result. 
Result so far: 123.0
Subtract 234 from 309 to get 75.
Append the next digit (7) from the dividend to 75 and continue with: 757 / 78

On to step 5:
The number 78 fits into 757 9 times, leaving a remainder of 55.
The next digit of our result is 9. 
Result so far: 1239.0
If we subtract 702 from 757, we get 55.
Append the next digit (2) from the dividend to 55 and continue with: 552 / 78

Step 6:
552 divided by 78 is 7 with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 12397.0
Deduct 546 from 552 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
78 goes into 60 0 times with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 12397.0
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 8:
600 divided by 78 is 7 with a remainder of 54.
Put 7 as the next digit of the answer. 
Result so far: 12397.07
Subtract 546 from 600 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 9:
When dividing 540 by 78, we get 6 with a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 12397.076
Deduct 468 from 540 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 10:
78 can be fit into 720 9 times, resulting in a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 12397.0769
Subtract 702 from 720 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 11:
If we divide 180 by 78, we get 2 and a remainder of 24.
The next digit of our result is 2. 
Result so far: 12397.07692
If we take 156 away from 180, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 12:
78 goes into 240 3 times with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 12397.076923
The remainder is 6 after subtracting 234 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 13:
The number 78 fits into 60 0 times, leaving a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 12397.076923
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 14:
When dividing 600 by 78, we get 7 with a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 12397.07692307
Subtract 546 from 600 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

After the division, we end up with 12397.07692307 and a remainder of 5.4e-08.
