We look at the division of 973293 by 78 
The aim is to understand the frequency of 78 in 973293.

Going ahead to step 1:
78 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 78

Going ahead to step 2:
If we divide 97 by 78, we get 1 and a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 78 from 97 and we're left with 19.
Grab the next digit (3) from the dividend, add it to 19, then carry on: 193 / 78

Let's proceed to step 3:
When dividing 193 by 78, we get 2 with a remainder of 37.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 156 from 193 and we're left with 37.
Take the next digit (2) from the dividend and append it to 37, then repeat: 372 / 78

Moving on to step 4:
78 goes into 372 4 times with a remainder of 60.
The next digit of our result is 4. 
Result so far: 124.0
If we take 312 away from 372, we end up with 60.
Take the next digit (9) from the dividend and append it to 60, then repeat: 609 / 78

Let's proceed to step 5:
78 can be fit into 609 7 times, resulting in a remainder of 63.
Write down 7 as next digit of the result. 
Result so far: 1247.0
Deduct 546 from 609 and we're left with 63.
Take the next digit (3) from the dividend and append it to 63, then repeat: 633 / 78

Let's proceed to step 6:
78 goes into 633 8 times with a remainder of 9.
Use 8 as the next digit of our solution. 
Result so far: 12478.0
Subtracting 624 from 633 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
The number 78 fits into 90 1 times, leaving a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 12478.1
Subtract 78 from 90 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.

On to step 8:
78 can be fit into 120 1 times, resulting in a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 12478.11
The remainder is 42 after subtracting 78 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

After the division, we end up with 12478.11 and a remainder of 0.042.
