We're dividing 543062 by 78 
The aim is to understand the frequency of 78 in 543062.

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
The remainder is 5 after subtracting 0 from 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 78

Advancing to step 2:
The number 78 fits into 54 0 times, leaving a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 54, we get 54.
Grab the next digit (3) from the dividend, add it to 54, then carry on: 543 / 78

On to step 3:
If we divide 543 by 78, we get 6 and a remainder of 75.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 468 from 543 and we're left with 75.
Fetch the next digit (0) from the dividend, attach it to 75 and continue: 750 / 78

Let's proceed to step 4:
If we divide 750 by 78, we get 9 and a remainder of 48.
The number 9 becomes the next digit in our result. 
Result so far: 69.0
Deduct 702 from 750 and we're left with 48.
Append the next digit (6) from the dividend to 48 and continue with: 486 / 78

Step 5:
78 goes into 486 6 times with a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 696.0
Subtracting 468 from 486 leaves us with 18.
Grab the next digit (2) from the dividend, add it to 18, then carry on: 182 / 78

Advancing to step 6:
78 can be fit into 182 2 times, resulting in a remainder of 26.
Write down 2 as next digit of the result. 
Result so far: 6962.0
If we subtract 156 from 182, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 7:
The number 78 fits into 260 3 times, leaving a remainder of 26.
Record the quotient 3 as the next digit in the result. 
Result so far: 6962.3
Subtracting 234 from 260 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 8:
78 goes into 260 3 times with a remainder of 26.
The number 3 becomes the next digit in our result. 
Result so far: 6962.33
Subtracting 234 from 260 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Our division results in 6962.33 with a remaining 0.026.
