7719 divided by 54 
The aim is to understand the frequency of 54 in 7719.

Step 1:
The number 54 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 54

Moving on to step 2:
54 goes into 77 1 times with a remainder of 23.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 54 from 77 leaves us with 23.
Take the next digit (1) from the dividend and append it to 23, then repeat: 231 / 54

Moving on to step 3:
54 can be fit into 231 4 times, resulting in a remainder of 15.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtracting 216 from 231 leaves us with 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 54

Advancing to step 4:
159 divided by 54 is 2 with a remainder of 51.
Write down 2 as next digit of the result. 
Result so far: 142.0
Subtracting 108 from 159 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 5:
If we divide 510 by 54, we get 9 and a remainder of 24.
The next digit of our result is 9. 
Result so far: 142.9
Subtract 486 from 510 to 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.

Let's proceed to step 6:
When dividing 240 by 54, we get 4 with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 142.94
The remainder is 24 after subtracting 216 from 240.
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 7:
If we divide 240 by 54, we get 4 and a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 142.944
Deduct 216 from 240 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 142.944, with a leftover of 0.0024.
