330331 divided by 54 
The aim is to understand the frequency of 54 in 330331.

Moving on to step 1:
3 divided by 54 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 54

On to step 2:
If we divide 33 by 54, we get 0 and a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 33 after subtracting 0 from 33.
Bring next digit (0) of the dividend behind the 33 and repeat the process: 330 / 54

Let's proceed to step 3:
The number 54 fits into 330 6 times, leaving a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 324 from 330 to get 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 54

Advancing to step 4:
The number 54 fits into 63 1 times, leaving a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 61.0
Subtracting 54 from 63 leaves us with 9.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 54

Moving on to step 5:
93 divided by 54 is 1 with a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 611.0
Subtract 54 from 93 to get 39.
Bring next digit (1) of the dividend behind the 39 and repeat the process: 391 / 54

Moving on to step 6:
54 goes into 391 7 times with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 6117.0
If we take 378 away from 391, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
54 can be fit into 130 2 times, resulting in a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 6117.2
Deduct 108 from 130 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 8:
The number 54 fits into 220 4 times, leaving a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 6117.24
The remainder is 4 after subtracting 216 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
If we divide 40 by 54, we get 0 and a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 6117.24
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
When dividing 400 by 54, we get 7 with a remainder of 22.
Put 7 as the next digit of the answer. 
Result so far: 6117.2407
The remainder is 22 after subtracting 378 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 11:
If we divide 220 by 54, we get 4 and a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 6117.24074
If we take 216 away from 220, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 12:
When dividing 40 by 54, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 6117.24074
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 13:
400 divided by 54 is 7 with a remainder of 22.
Write down 7 as next digit of the result. 
Result so far: 6117.2407407
Deduct 378 from 400 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 14:
When dividing 220 by 54, we get 4 with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 6117.24074074
If we take 216 away from 220, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 6117.24074074 and a remainder of 4e-09.
