Let's divide 515769 by 54
The aim is to understand the frequency of 54 in 515769.

Let's proceed to step 1:
54 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 54

Let's proceed to step 2:
When dividing 51 by 54, we get 0 with a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Bring next digit (5) of the dividend behind the 51 and repeat the process: 515 / 54

Going ahead to step 3:
When dividing 515 by 54, we get 9 with a remainder of 29.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 486 from 515 to get 29.
Take the next digit (7) from the dividend and append it to 29, then repeat: 297 / 54

On to step 4:
The number 54 fits into 297 5 times, leaving a remainder of 27.
The next digit of our result is 5. 
Result so far: 95.0
Subtracting 270 from 297 leaves us with 27.
Include the next digit (6) from the dividend after 27, then repeat: 276 / 54

Let's proceed to step 5:
276 divided by 54 is 5 with a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 955.0
Subtract 270 from 276 to get 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 54

Going ahead to step 6:
If we divide 69 by 54, we get 1 and a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 9551.0
Deduct 54 from 69 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 7:
If we divide 150 by 54, we get 2 and a remainder of 42.
The next digit of our result is 2. 
Result so far: 9551.2
If we take 108 away from 150, we end up 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.

Step 8:
When dividing 420 by 54, we get 7 with a remainder of 42.
The number 7 becomes the next digit in our result. 
Result so far: 9551.27
Subtracting 378 from 420 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.

On to step 9:
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: 9551.277
If we take 378 away from 420, we end up 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.

The final result is 9551.277 with a remainder of 0.0042.
