579333 ÷ 54 
The aim is to understand the frequency of 54 in 579333.

Moving on to step 1:
When dividing 5 by 54, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 54

Moving on to step 2:
If we divide 57 by 54, we get 1 and a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 54 away from 57, we end up with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 54

Step 3:
If we divide 39 by 54, we get 0 and a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we subtract 0 from 39, we get 39.
Grab the next digit (3) from the dividend, add it to 39, then carry on: 393 / 54

Advancing to step 4:
The number 54 fits into 393 7 times, leaving a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 107.0
Subtracting 378 from 393 leaves us with 15.
Grab the next digit (3) from the dividend, add it to 15, then carry on: 153 / 54

Going ahead to step 5:
54 can be fit into 153 2 times, resulting in a remainder of 45.
Record the quotient 2 as the next digit in the result. 
Result so far: 1072.0
If we subtract 108 from 153, we get 45.
Take the next digit (3) from the dividend and append it to 45, then repeat: 453 / 54

Advancing to step 6:
When dividing 453 by 54, we get 8 with a remainder of 21.
Write down 8 as next digit of the result. 
Result so far: 10728.0
Subtracting 432 from 453 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 7:
210 divided by 54 is 3 with a remainder of 48.
Put 3 as the next digit of the answer. 
Result so far: 10728.3
Deduct 162 from 210 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 8:
54 can be fit into 480 8 times, resulting in a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 10728.38
Subtracting 432 from 480 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 9:
54 can be fit into 480 8 times, resulting in a remainder of 48.
The next digit of our result is 8. 
Result so far: 10728.388
If we take 432 away from 480, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

After the division, we end up with 10728.388 and a remainder of 0.0048.
