We divide 539804 by 54
The aim is to understand the frequency of 54 in 539804.

Going ahead to step 1:
54 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 54

Going ahead to step 2:
54 goes into 53 0 times with a remainder of 53.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Fetch the next digit (9) from the dividend, attach it to 53 and continue: 539 / 54

Going ahead to step 3:
54 can be fit into 539 9 times, resulting in a remainder of 53.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 486 from 539 leaves us with 53.
Fetch the next digit (8) from the dividend, attach it to 53 and continue: 538 / 54

Let's proceed to step 4:
54 can be fit into 538 9 times, resulting in a remainder of 52.
Put 9 as the next digit of the answer. 
Result so far: 99.0
Subtracting 486 from 538 leaves us with 52.
Append the next digit (0) from the dividend to 52 and continue with: 520 / 54

On to step 5:
54 can be fit into 520 9 times, resulting in a remainder of 34.
Record the quotient 9 as the next digit in the result. 
Result so far: 999.0
Subtracting 486 from 520 leaves us with 34.
Take the next digit (4) from the dividend and append it to 34, then repeat: 344 / 54

Step 6:
If we divide 344 by 54, we get 6 and a remainder of 20.
The next digit of our result is 6. 
Result so far: 9996.0
Deduct 324 from 344 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 7:
If we divide 200 by 54, we get 3 and a remainder of 38.
Write down 3 as next digit of the result. 
Result so far: 9996.3
The remainder is 38 after subtracting 162 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 8:
54 goes into 380 7 times with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 9996.37
Deduct 378 from 380 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 9:
The number 54 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 9996.37
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 10:
54 can be fit into 200 3 times, resulting in a remainder of 38.
Record the quotient 3 as the next digit in the result. 
Result so far: 9996.3703
Subtracting 162 from 200 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 11:
54 can be fit into 380 7 times, resulting in a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 9996.37037
Subtract 378 from 380 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 12:
54 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 9996.37037
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 13:
If we divide 200 by 54, we get 3 and a remainder of 38.
Use 3 as the next digit of our solution. 
Result so far: 9996.3703703
If we subtract 162 from 200, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 14:
If we divide 380 by 54, we get 7 and a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 9996.37037037
If we take 378 away from 380, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 9996.37037037 and a remainder of 2e-09.
