261015 ÷ 54 
The aim is to understand the frequency of 54 in 261015.

On to step 1:
The number 54 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 54

Step 2:
54 goes into 26 0 times with a remainder of 26.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 26 leaves us with 26.
Include the next digit (1) from the dividend after 26, then repeat: 261 / 54

Let's proceed to step 3:
When dividing 261 by 54, we get 4 with a remainder of 45.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 216 from 261 and we're left with 45.
Append the next digit (0) from the dividend to 45 and continue with: 450 / 54

Step 4:
The number 54 fits into 450 8 times, leaving a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 48.0
If we subtract 432 from 450, we get 18.
Take the next digit (1) from the dividend and append it to 18, then repeat: 181 / 54

Let's proceed to step 5:
54 goes into 181 3 times with a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 483.0
Deduct 162 from 181 and we're left with 19.
Grab the next digit (5) from the dividend, add it to 19, then carry on: 195 / 54

Let's proceed to step 6:
54 can be fit into 195 3 times, resulting in a remainder of 33.
Write down 3 as next digit of the result. 
Result so far: 4833.0
Deduct 162 from 195 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 7:
When dividing 330 by 54, we get 6 with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 4833.6
If we subtract 324 from 330, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
54 can be fit into 60 1 times, resulting in a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 4833.61
The remainder is 6 after subtracting 54 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 9:
If we divide 60 by 54, we get 1 and a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 4833.611
Subtracting 54 from 60 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The quotient of the division is 4833.611, and the remainder is 0.0006.
