620573 ÷ 54 
The aim is to understand the frequency of 54 in 620573.

Let's proceed to step 1:
54 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 54

Let's proceed to step 2:
When dividing 62 by 54, we get 1 with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 54 from 62, we get 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 54

Advancing to step 3:
54 goes into 80 1 times with a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we subtract 54 from 80, we get 26.
Take the next digit (5) from the dividend and append it to 26, then repeat: 265 / 54

Step 4:
The number 54 fits into 265 4 times, leaving a remainder of 49.
Record the quotient 4 as the next digit in the result. 
Result so far: 114.0
The remainder is 49 after subtracting 216 from 265.
Fetch the next digit (7) from the dividend, attach it to 49 and continue: 497 / 54

Step 5:
54 goes into 497 9 times with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 1149.0
Deduct 486 from 497 and we're left with 11.
Fetch the next digit (3) from the dividend, attach it to 11 and continue: 113 / 54

Going ahead to step 6:
54 can be fit into 113 2 times, resulting in a remainder of 5.
Use 2 as the next digit of our solution. 
Result so far: 11492.0
Subtracting 108 from 113 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
The number 54 fits into 50 0 times, leaving a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 11492.0
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 8:
If we divide 500 by 54, we get 9 and a remainder of 14.
The number 9 becomes the next digit in our result. 
Result so far: 11492.09
Deduct 486 from 500 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 9:
140 divided by 54 is 2 with a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 11492.092
If we subtract 108 from 140, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 10:
54 goes into 320 5 times with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 11492.0925
If we take 270 away from 320, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 11:
54 can be fit into 500 9 times, resulting in a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 11492.09259
If we take 486 away from 500, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 12:
When dividing 140 by 54, we get 2 with a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 11492.092592
Subtracting 108 from 140 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 13:
54 can be fit into 320 5 times, resulting in a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 11492.0925925
Deduct 270 from 320 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 14:
When dividing 500 by 54, we get 9 with a remainder of 14.
Record the quotient 9 as the next digit in the result. 
Result so far: 11492.09259259
Subtract 486 from 500 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final result is 11492.09259259 with a remainder of 1.4e-08.
