We're dividing 530917 by 78 
The aim is to understand the frequency of 78 in 530917.

Advancing to step 1:
The number 78 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 78

Let's proceed to step 2:
78 can be fit into 53 0 times, resulting in a remainder of 53.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Append the next digit (0) from the dividend to 53 and continue with: 530 / 78

On to step 3:
The number 78 fits into 530 6 times, leaving a remainder of 62.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 468 from 530 and we're left with 62.
Append the next digit (9) from the dividend to 62 and continue with: 629 / 78

Let's proceed to step 4:
629 divided by 78 is 8 with a remainder of 5.
The number 8 becomes the next digit in our result. 
Result so far: 68.0
Deduct 624 from 629 and we're left with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 78

Let's proceed to step 5:
78 goes into 51 0 times with a remainder of 51.
The next digit of our result is 0. 
Result so far: 680.0
The remainder is 51 after subtracting 0 from 51.
Fetch the next digit (7) from the dividend, attach it to 51 and continue: 517 / 78

On to step 6:
78 goes into 517 6 times with a remainder of 49.
Put 6 as the next digit of the answer. 
Result so far: 6806.0
If we subtract 468 from 517, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 7:
The number 78 fits into 490 6 times, leaving a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 6806.6
Subtracting 468 from 490 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 8:
78 can be fit into 220 2 times, resulting in a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 6806.62
If we take 156 away from 220, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 9:
The number 78 fits into 640 8 times, leaving a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 6806.628
Subtract 624 from 640 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 10:
78 goes into 160 2 times with a remainder of 4.
The next digit of our result is 2. 
Result so far: 6806.6282
Subtracting 156 from 160 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 11:
The number 78 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 6806.6282
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 12:
400 divided by 78 is 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 6806.628205
Deduct 390 from 400 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 13:
78 goes into 100 1 times with a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 6806.6282051
If we subtract 78 from 100, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 14:
78 goes into 220 2 times with a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 6806.62820512
Deduct 156 from 220 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final outcome is 6806.62820512, with a leftover of 6.4e-08.
