Let's divide 912807 by 78
The aim is to understand the frequency of 78 in 912807.

Going ahead to step 1:
If we divide 9 by 78, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 78

Let's proceed to step 2:
91 divided by 78 is 1 with a remainder of 13.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 78 from 91 to get 13.
Bring next digit (2) of the dividend behind the 13 and repeat the process: 132 / 78

Going ahead to step 3:
When dividing 132 by 78, we get 1 with a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtract 78 from 132 to get 54.
Take the next digit (8) from the dividend and append it to 54, then repeat: 548 / 78

On to step 4:
The number 78 fits into 548 7 times, leaving a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 117.0
Deduct 546 from 548 and we're left with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 78

Moving on to step 5:
78 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 1170.0
Subtract 0 from 20 to get 20.
Fetch the next digit (7) from the dividend, attach it to 20 and continue: 207 / 78

Advancing to step 6:
When dividing 207 by 78, we get 2 with a remainder of 51.
The number 2 becomes the next digit in our result. 
Result so far: 11702.0
If we subtract 156 from 207, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 7:
78 can be fit into 510 6 times, resulting in a remainder of 42.
The next digit of our result is 6. 
Result so far: 11702.6
Subtract 468 from 510 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 8:
78 can be fit into 420 5 times, resulting in a remainder of 30.
The next digit of our result is 5. 
Result so far: 11702.65
Subtracting 390 from 420 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 9:
300 divided by 78 is 3 with a remainder of 66.
Write down 3 as next digit of the result. 
Result so far: 11702.653
If we take 234 away from 300, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 10:
78 goes into 660 8 times with a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 11702.6538
Subtracting 624 from 660 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 11:
78 can be fit into 360 4 times, resulting in a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 11702.65384
Subtracting 312 from 360 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 12:
480 divided by 78 is 6 with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 11702.653846
Subtract 468 from 480 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 13:
78 goes into 120 1 times with a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 11702.6538461
Subtract 78 from 120 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 14:
78 can be fit into 420 5 times, resulting in a remainder of 30.
The next digit of our result is 5. 
Result so far: 11702.65384615
Subtract 390 from 420 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

In conclusion, the division gives 11702.65384615 with a balance of 3e-08.
