931578 divided by 54 
The aim is to understand the frequency of 54 in 931578.

Going ahead to step 1:
9 divided by 54 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 54

On to step 2:
The number 54 fits into 93 1 times, leaving a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 54 from 93 to get 39.
Include the next digit (1) from the dividend after 39, then repeat: 391 / 54

Let's proceed to step 3:
The number 54 fits into 391 7 times, leaving a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtract 378 from 391 to get 13.
Grab the next digit (5) from the dividend, add it to 13, then carry on: 135 / 54

Going ahead to step 4:
The number 54 fits into 135 2 times, leaving a remainder of 27.
The next digit of our result is 2. 
Result so far: 172.0
Deduct 108 from 135 and we're left with 27.
Include the next digit (7) from the dividend after 27, then repeat: 277 / 54

On to step 5:
The number 54 fits into 277 5 times, leaving a remainder of 7.
Record the quotient 5 as the next digit in the result. 
Result so far: 1725.0
If we subtract 270 from 277, we get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 54

Going ahead to step 6:
When dividing 78 by 54, we get 1 with a remainder of 24.
Put 1 as the next digit of the answer. 
Result so far: 17251.0
Subtract 54 from 78 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.

Advancing to step 7:
When dividing 240 by 54, we get 4 with a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 17251.4
Subtracting 216 from 240 leaves us 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.

Advancing to step 8:
When dividing 240 by 54, we get 4 with a remainder of 24.
The next digit of our result is 4. 
Result so far: 17251.44
If we subtract 216 from 240, 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.

The quotient of the division is 17251.44, and the remainder is 0.024.
