We look at the division of 624635 by 54 
The aim is to understand the frequency of 54 in 624635.

Moving on to step 1:
54 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 54

Step 2:
54 goes into 62 1 times with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 8 after subtracting 54 from 62.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 54

Step 3:
If we divide 84 by 54, we get 1 and a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we take 54 away from 84, we end up with 30.
Grab the next digit (6) from the dividend, add it to 30, then carry on: 306 / 54

On to step 4:
When dividing 306 by 54, we get 5 with a remainder of 36.
Use 5 as the next digit of our solution. 
Result so far: 115.0
Deduct 270 from 306 and we're left with 36.
Bring next digit (3) of the dividend behind the 36 and repeat the process: 363 / 54

On to step 5:
54 can be fit into 363 6 times, resulting in a remainder of 39.
The number 6 becomes the next digit in our result. 
Result so far: 1156.0
Subtracting 324 from 363 leaves us with 39.
Grab the next digit (5) from the dividend, add it to 39, then carry on: 395 / 54

Advancing to step 6:
395 divided by 54 is 7 with a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 11567.0
Subtracting 378 from 395 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 7:
170 divided by 54 is 3 with a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 11567.3
Deduct 162 from 170 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 8:
The number 54 fits into 80 1 times, leaving a remainder of 26.
The number 1 becomes the next digit in our result. 
Result so far: 11567.31
Subtract 54 from 80 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 9:
When dividing 260 by 54, we get 4 with a remainder of 44.
Put 4 as the next digit of the answer. 
Result so far: 11567.314
The remainder is 44 after subtracting 216 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 10:
54 goes into 440 8 times with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 11567.3148
Subtracting 432 from 440 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 11:
When dividing 80 by 54, we get 1 with a remainder of 26.
Record the quotient 1 as the next digit in the result. 
Result so far: 11567.31481
If we subtract 54 from 80, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 12:
If we divide 260 by 54, we get 4 and a remainder of 44.
Record the quotient 4 as the next digit in the result. 
Result so far: 11567.314814
The remainder is 44 after subtracting 216 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 13:
440 divided by 54 is 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 11567.3148148
If we subtract 432 from 440, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 14:
The number 54 fits into 80 1 times, leaving a remainder of 26.
Write down 1 as next digit of the result. 
Result so far: 11567.31481481
If we subtract 54 from 80, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

In conclusion, the division gives 11567.31481481 with a balance of 2.6e-08.
