Let's divide 546138 by 78
The aim is to understand the frequency of 78 in 546138.

Advancing to step 1:
If we divide 5 by 78, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 78

Let's proceed to step 2:
The number 78 fits into 54 0 times, leaving a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 54 leaves us with 54.
Include the next digit (6) from the dividend after 54, then repeat: 546 / 78

Going ahead to step 3:
78 can be fit into 546 7 times, resulting in a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 546 from 546 to get 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 78

Going ahead to step 4:
78 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 70.0
If we subtract 0 from 1, we get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 78

Step 5:
78 goes into 13 0 times with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 700.0
Deduct 0 from 13 and we're left with 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 78

Let's proceed to step 6:
When dividing 138 by 78, we get 1 with a remainder of 60.
Record the quotient 1 as the next digit in the result. 
Result so far: 7001.0
Subtracting 78 from 138 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 7:
The number 78 fits into 600 7 times, leaving a remainder of 54.
Use 7 as the next digit of our solution. 
Result so far: 7001.7
If we take 546 away from 600, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 8:
78 can be fit into 540 6 times, resulting in a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 7001.76
If we take 468 away from 540, we end up 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.

Going ahead to step 9:
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: 7001.769
If we subtract 702 from 720, we 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 10:
180 divided by 78 is 2 with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 7001.7692
If we subtract 156 from 180, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 11:
The number 78 fits into 240 3 times, leaving a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 7001.76923
If we subtract 234 from 240, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 12:
The number 78 fits into 60 0 times, leaving a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 7001.76923
If we subtract 0 from 60, we 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.

Let's proceed to step 13:
600 divided by 78 is 7 with a remainder of 54.
Use 7 as the next digit of our solution. 
Result so far: 7001.7692307
If we take 546 away from 600, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 14:
78 can be fit into 540 6 times, resulting in a remainder of 72.
Write down 6 as next digit of the result. 
Result so far: 7001.76923076
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.

The final result is 7001.76923076 with a remainder of 7.2e-08.
