We look at the division of 626560 by 54 
The aim is to understand the frequency of 54 in 626560.

Let's proceed to step 1:
54 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 54

Let's proceed to step 2:
If we divide 62 by 54, we get 1 and a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 54 from 62 to get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 54

Going ahead to step 3:
86 divided by 54 is 1 with a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtracting 54 from 86 leaves us with 32.
Include the next digit (5) from the dividend after 32, then repeat: 325 / 54

On to step 4:
54 can be fit into 325 6 times, resulting in a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 116.0
The remainder is 1 after subtracting 324 from 325.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 54

Step 5:
54 goes into 16 0 times with a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 1160.0
Deduct 0 from 16 and we're left with 16.
Bring next digit (0) of the dividend behind the 16 and repeat the process: 160 / 54

Going ahead to step 6:
160 divided by 54 is 2 with a remainder of 52.
Write down 2 as next digit of the result. 
Result so far: 11602.0
Subtract 108 from 160 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 7:
If we divide 520 by 54, we get 9 and a remainder of 34.
The number 9 becomes the next digit in our result. 
Result so far: 11602.9
If we subtract 486 from 520, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 8:
If we divide 340 by 54, we get 6 and a remainder of 16.
The next digit of our result is 6. 
Result so far: 11602.96
The remainder is 16 after subtracting 324 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 9:
If we divide 160 by 54, we get 2 and a remainder of 52.
The number 2 becomes the next digit in our result. 
Result so far: 11602.962
Deduct 108 from 160 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 10:
When dividing 520 by 54, we get 9 with a remainder of 34.
Write down 9 as next digit of the result. 
Result so far: 11602.9629
Subtract 486 from 520 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 11:
340 divided by 54 is 6 with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 11602.96296
Deduct 324 from 340 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 12:
54 can be fit into 160 2 times, resulting in a remainder of 52.
The next digit of our result is 2. 
Result so far: 11602.962962
The remainder is 52 after subtracting 108 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 13:
The number 54 fits into 520 9 times, leaving a remainder of 34.
Use 9 as the next digit of our solution. 
Result so far: 11602.9629629
Subtracting 486 from 520 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 14:
340 divided by 54 is 6 with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 11602.96296296
If we take 324 away from 340, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 11602.96296296, with a leftover of 1.6e-08.
