We're dividing 550586 by 54 
The aim is to understand the frequency of 54 in 550586.

Moving on to step 1:
If we divide 5 by 54, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 54

Moving on to step 2:
54 goes into 55 1 times with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 54 from 55 to get 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 54

Let's proceed to step 3:
54 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 10 after subtracting 0 from 10.
Fetch the next digit (5) from the dividend, attach it to 10 and continue: 105 / 54

Let's proceed to step 4:
When dividing 105 by 54, we get 1 with a remainder of 51.
Put 1 as the next digit of the answer. 
Result so far: 101.0
The remainder is 51 after subtracting 54 from 105.
Include the next digit (8) from the dividend after 51, then repeat: 518 / 54

Advancing to step 5:
The number 54 fits into 518 9 times, leaving a remainder of 32.
The next digit of our result is 9. 
Result so far: 1019.0
Deduct 486 from 518 and we're left with 32.
Include the next digit (6) from the dividend after 32, then repeat: 326 / 54

Step 6:
When dividing 326 by 54, we get 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 10196.0
Subtract 324 from 326 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.

On to step 7:
20 divided by 54 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 10196.0
Subtracting 0 from 20 leaves us 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.

Moving on to step 8:
54 can be fit into 200 3 times, resulting in a remainder of 38.
Use 3 as the next digit of our solution. 
Result so far: 10196.03
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.

Moving on to step 9:
When dividing 380 by 54, we get 7 with a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 10196.037
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.

Going ahead to step 10:
54 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 10196.037
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.

Going ahead to step 11:
When dividing 200 by 54, we get 3 with a remainder of 38.
Write down 3 as next digit of the result. 
Result so far: 10196.03703
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.

On to step 12:
When dividing 380 by 54, we get 7 with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 10196.037037
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.

Step 13:
If we divide 20 by 54, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 10196.037037
Subtracting 0 from 20 leaves us 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.

Advancing to step 14:
If we divide 200 by 54, we get 3 and a remainder of 38.
The next digit of our result is 3. 
Result so far: 10196.03703703
Deduct 162 from 200 and we're left 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.

The quotient of the division is 10196.03703703, and the remainder is 3.8e-08.
