Let's divide 967580 by 78
The aim is to understand the frequency of 78 in 967580.

Moving on to step 1:
If we divide 9 by 78, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 78

On to step 2:
When dividing 96 by 78, we get 1 with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 78 from 96 and we're left with 18.
Bring next digit (7) of the dividend behind the 18 and repeat the process: 187 / 78

On to step 3:
78 goes into 187 2 times with a remainder of 31.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 156 away from 187, we end up with 31.
Fetch the next digit (5) from the dividend, attach it to 31 and continue: 315 / 78

On to step 4:
78 goes into 315 4 times with a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 124.0
If we subtract 312 from 315, we get 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 78

Step 5:
When dividing 38 by 78, we get 0 with a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 1240.0
Deduct 0 from 38 and we're left with 38.
Take the next digit (0) from the dividend and append it to 38, then repeat: 380 / 78

Advancing to step 6:
78 goes into 380 4 times with a remainder of 68.
Write down 4 as next digit of the result. 
Result so far: 12404.0
Deduct 312 from 380 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 7:
If we divide 680 by 78, we get 8 and a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 12404.8
The remainder is 56 after subtracting 624 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 8:
If we divide 560 by 78, we get 7 and a remainder of 14.
The next digit of our result is 7. 
Result so far: 12404.87
If we take 546 away from 560, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 9:
140 divided by 78 is 1 with a remainder of 62.
Put 1 as the next digit of the answer. 
Result so far: 12404.871
If we take 78 away from 140, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 10:
If we divide 620 by 78, we get 7 and a remainder of 74.
Use 7 as the next digit of our solution. 
Result so far: 12404.8717
Subtract 546 from 620 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 11:
740 divided by 78 is 9 with a remainder of 38.
Write down 9 as next digit of the result. 
Result so far: 12404.87179
Subtract 702 from 740 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 12:
78 goes into 380 4 times with a remainder of 68.
Use 4 as the next digit of our solution. 
Result so far: 12404.871794
Subtracting 312 from 380 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 13:
If we divide 680 by 78, we get 8 and a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 12404.8717948
The remainder is 56 after subtracting 624 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 14:
78 goes into 560 7 times with a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 12404.87179487
Deduct 546 from 560 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final result is 12404.87179487 with a remainder of 1.4e-08.
