Let's divide 546585 by 78
The aim is to understand the frequency of 78 in 546585.

Advancing to step 1:
The number 78 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 78

Step 2:
54 divided by 78 is 0 with a remainder of 54.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 54, we end up with 54.
Take the next digit (6) from the dividend and append it to 54, then repeat: 546 / 78

Let's proceed to step 3:
546 divided by 78 is 7 with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 546 away from 546, we end up with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 78

On to step 4:
78 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 70.0
Subtract 0 from 5 to get 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 78

Going ahead to step 5:
58 divided by 78 is 0 with a remainder of 58.
Put 0 as the next digit of the answer. 
Result so far: 700.0
Subtract 0 from 58 to get 58.
Include the next digit (5) from the dividend after 58, then repeat: 585 / 78

On to step 6:
If we divide 585 by 78, we get 7 and a remainder of 39.
Record the quotient 7 as the next digit in the result. 
Result so far: 7007.0
Subtract 546 from 585 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 7:
When dividing 390 by 78, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 7007.5
Subtracting 390 from 390 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
0 divided by 78 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 7007.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
78 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 7007.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 7007.5 and a remainder of 0.0.
