Let's divide 645882 by 54
The aim is to understand the frequency of 54 in 645882.

Going ahead to step 1:
If we divide 6 by 54, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 54

Moving on to step 2:
64 divided by 54 is 1 with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 54 from 64, we get 10.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 54

Going ahead to step 3:
When dividing 105 by 54, we get 1 with a remainder of 51.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we take 54 away from 105, we end up with 51.
Append the next digit (8) from the dividend to 51 and continue with: 518 / 54

Advancing to step 4:
54 goes into 518 9 times with a remainder of 32.
Write down 9 as next digit of the result. 
Result so far: 119.0
Subtracting 486 from 518 leaves us with 32.
Grab the next digit (8) from the dividend, add it to 32, then carry on: 328 / 54

Going ahead to step 5:
If we divide 328 by 54, we get 6 and a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 1196.0
Subtract 324 from 328 to get 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 54

Advancing to step 6:
42 divided by 54 is 0 with a remainder of 42.
The next digit of our result is 0. 
Result so far: 11960.0
Subtracting 0 from 42 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 7:
420 divided by 54 is 7 with a remainder of 42.
Record the quotient 7 as the next digit in the result. 
Result so far: 11960.7
The remainder is 42 after subtracting 378 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 8:
54 can be fit into 420 7 times, resulting in a remainder of 42.
Record the quotient 7 as the next digit in the result. 
Result so far: 11960.77
Subtract 378 from 420 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

In conclusion, the division gives 11960.77 with a balance of 0.042.
